BYOK AI

Connect AI with your own API key

™Cayia uses a BYOK model, which means Bring Your Own Key. You control the AI provider, usage, and cost.

What this helps you do

Connecting an API key unlocks advanced AI features, including financial questions, receipt analysis, summaries, inventory checks, project guidance, tenant balances, POS sales questions, cash register review, and Service Tickets questions.

™Cayia does not include an API key inside the subscription. To use advanced AI features, the user must connect their own API key from a compatible provider such as OpenAI, Gemini, Mammouth, or DeepSeek when available. This gives the user more control, privacy, and flexibility.

When to use it

Use this setup before asking AI to analyze receipts, review financial health, summarize projects, search inventory, check tenant balances, review sales, inspect tickets, or answer questions about your business data.

Steps

  1. Create an API key with a compatible provider such as OpenAI, Gemini, or Mammouth.
  2. Open ™Cayia and go to Settings, then AI Config.
  3. Choose the provider you want to connect.
  4. Paste your API key into the secure API key field.
  5. Save the configuration and run a simple AI test question.
  6. If the provider supports model selection, choose the model that fits your cost and quality needs.

Important tips

  • Never share your API key in screenshots, emails, or support messages.
  • Rotate the key from your provider dashboard if you believe it was exposed.
  • ™Cayia can still be used without AI for core tracking features.
  • Ask specific questions for better answers, such as "What is the balance for Carlos?", "Which products are low stock?", or "What happened in cash register today?"
  • When supported by your provider, AI can use tools to search contracts, tenant balances, products, low stock, sales, cash register sessions, and financial summaries.

Common problems

  • If AI does not respond, confirm the API key is active and has billing enabled with the provider.
  • If a provider is not available yet, choose another compatible provider until support is added.
  • If AI answers the wrong area, mention the module clearly: POS, Finance, Rent Management, Project Contracts, Inventory, Service Tickets, or Cash Register.
  • If names or Spanish accents are not recognized, try the exact customer, tenant, project, product, or receipt number.

Practical AI examples

  • Finance: "How much did I spend this month?" or "What is my net income this week?"
  • Inventory: "Which products are low stock?" or "Do I have this product available?"
  • POS: "How much cash did this receipt receive?" or "What did this cashier sell today?"
  • Project Contracts: "Is this project profitable?" or "What materials are over budget?"
  • Rent Management: "What is Carlos' balance?" or "Which tenants are overdue?"
  • Cash Register: "Was the drawer short today?" or "Who closed the register?"
  • Service Tickets: "What parts did Victor use this week?" or "Which tickets are still in progress?"

Dashboard

Read your financial dashboard

The dashboard gives you a quick financial snapshot across income, expenses, estimated tax, POS sales, and trends.

What this helps you do

Use the dashboard to understand what came in, what went out, how POS is performing, and where your money is concentrated.

When to use it

Use it at the start or end of each day, before making a purchase, after importing receipts, or before reviewing taxes.

Steps

  1. Open Dashboard from the sidebar.
  2. Review income, expenses, estimated tax owed, and POS sales today.
  3. Use quick actions to create a sale, scan a receipt, log income, or ask AI.
  4. Read charts to compare income and expenses over time.
  5. Use category breakdowns to spot the areas consuming the most budget.

Important tips

  • Dashboard totals are only as accurate as the income, expense, POS, and project data entered.
  • Estimated tax is an operational estimate, not a replacement for tax advice.

Common problems

  • If a chart looks empty, add income, receipts, or sales first.
  • If values look old, refresh the app and confirm sync status.

Income

Track income

Add and organize money coming into your business or personal operation.

What this helps you do

Income tracking helps you understand revenue from side jobs, deliveries, services, projects, stores, fish markets, weekly work, monthly work, active income, passive income, and non-POS payments.

When to use it

Use it when you receive cash, digital payments, tips, project deposits, service income, or non-POS revenue.

Steps

  1. Open the income or finances area. The Log Income screen supports English and Spanish labels.
  2. Choose the option to log income.
  3. Choose the platform/source, such as Uber, DoorDash, Fiverr, Store, Fish market, client work, or another income source.
  4. Enter the date earned, amount, hours worked when relevant, and notes.
  5. Save the entry and confirm it appears in recent transactions.
  6. Use search or filters to find older income entries.
  7. When deleting an income entry, review the confirmation message before approving the delete.

Important tips

  • Use consistent sources and categories to make reports easier to read.
  • Use notes to explain tips, cash payments, platform bonuses, refunds, or unusual income.
  • Delete only after checking the date and amount. Synced devices need the delete record so the same income does not reappear.
  • If you work multiple gigs, separate each platform instead of mixing everything into one general income label.

Common problems

  • If income does not show on the dashboard, confirm the date is inside the visible reporting period.
  • If the wrong language appears, use the website/app language selector and reopen the income modal.
  • If duplicate income appears after sync, delete the duplicate once and allow sync to finish before entering it again.
  • If AI or reports cannot identify a source, make the platform/source name more specific.

Expenses & Receipts

Record expenses and receipts

Track spending, scan receipts, attach evidence, and use AI to speed up entry.

What this helps you do

This area helps you capture business costs, correct submitted receipts, mark refunds/returns, and keep the proof needed for reports, taxes, and project profitability.

When to use it

Use it after buying materials, fuel, tools, inventory, supplies, meals, or any expense you need to track.

Steps

  1. Open finances, expenses, or the scan receipt quick action.
  2. Take a receipt photo or upload an image/document.
  3. If AI is enabled, allow ™Cayia to read vendor, amount, date, and category suggestions.
  4. Review and correct vendor/store, total, category, date, deductible status, refund/return status, and notes before saving.
  5. Attach evidence and assign the expense to a category or project when needed.
  6. To fix a submitted receipt later, open Finances > Import Receipts, select the receipt, edit the fields, and save the correction.

Important tips

  • Always review AI-detected values before saving.
  • Use the refund/return checkbox when the transaction is money coming back, store credit, or a returned purchase. That checkbox is the final instruction for how the receipt should be treated.
  • Use categories that match how you want to export reports later.
  • Edit the submitted receipt instead of deleting and importing again when the receipt simply needs a corrected value.
  • Attach clear images so project reports and rental/property records have usable proof later.

Common problems

  • If a receipt scan is wrong, retake the photo with better lighting and a flat angle, or edit the submitted receipt manually.
  • If AI does not analyze, check your API key configuration.
  • If a refund was detected as an expense, open the receipt edit screen and turn on the refund/return checkbox.
  • If a date or vendor is wrong, edit the receipt from Finances > Import Receipts and save the correction.
  • If an attachment is missing on another device, run file synchronization and confirm temporary cloud files were not purged.

POS / Cashier

Use the POS / Cashier

Run sales, search products, scan barcodes, charge customers, track cash received/change, and review past sales.

What this helps you do

The cashier module is for direct sales and store-style operations that need products, receipts, stock deduction, cash tracking, and sales reports.

When to use it

Use it when selling a product or service at the counter, from a device, or during mobile business activity.

Steps

  1. Open Cashier (POS) from the sidebar.
  2. Choose New Sale.
  3. Search for products or scan a barcode.
  4. Add quantities, discounts, or adjustments when needed.
  5. Choose the payment method. For cash, enter the cash received so Cayia can calculate change.
  6. Confirm the sale, generate the receipt, and allow Cayia to update inventory for unit or weight-based products.
  7. Open sales reports to review previous sales.

Important tips

  • Keep inventory updated so POS product search is accurate.
  • Use user or cashier accounts when multiple people sell from the same business.
  • For cash sales, enter the amount received before confirming so the receipt and AI can show the correct change.
  • Stock is updated when a sale is saved; refresh sync if another device needs to see the latest stock.

Common problems

  • If POS cannot find a product, confirm the product exists and the barcode matches.
  • If stock looks wrong after a sale, refresh sync and review recent sales or manual stock edits.
  • If a cash sale shows the wrong change, review the cash received value on the sale detail or receipt.

POS / Cashier

Balance the Cash Register

Use Cash Register when you need to open a drawer, track cash sales, count money, close the session, print reports, and review cash differences.

What this helps you do

Cash Register, also called drawer balancing or Cuadre de Caja, gives owners and cashiers a live view of the drawer. It tracks opening cash, cash sales, expected cash, counted cash, money left in the drawer, money removed, who opened/closed, and the final difference.

When to use it

Use it at the start and end of a shift, when a cashier changes, when closing a day, or whenever you need proof of how much cash should be in the drawer.

Steps

  1. Open Cashier (POS) and choose Cash Register or the Cash Register quick action.
  2. Open a register session with the date, opening cash amount, and optional notes.
  3. Run normal POS sales. Cash sales are added to the open register session automatically.
  4. Review the live expected amount: opening cash plus cash sales.
  5. At closing time, count the cash drawer and enter the counted amount.
  6. Enter how much cash stays in the drawer and how much is removed or deposited.
  7. Review the difference: balanced, over, or short.
  8. Close the register only after reviewing the summary.
  9. Print or save the register report when you need a shift or day-end record.
  10. Use the history filters for today, yesterday, week, month, or all sessions.

Important tips

  • The owner controls who can access Cash Register through Team Access permissions.
  • Existing cashiers may need the new Cash Register permission enabled by the owner.
  • Cash Register tracks cash sales only; card or other payments do not add cash to the drawer.
  • Each session has its own date and syncs across devices.
  • Deleted sessions use a sync-safe delete record, so other devices can remove the same session.
  • AI can answer questions about recent cash register sessions when your AI provider supports the data context.

Common problems

  • Cash Register is missing: ask the owner to enable the Cash Register permission under Team Access.
  • Cash sales do not appear: confirm there is an open register session and the sale payment method was cash.
  • The drawer is short or over: review cash received, change given, refunds, removed cash, and counted cash.
  • A cashier cannot close a session: confirm the cashier has the right POS and Cash Register permissions.
  • Report will not print: check the browser print dialog, selected printer, and popup/print permissions.

Inventory

Manage inventory and barcodes

Add products, import inventory, manage stock, generate barcodes, and prepare labels.

What this helps you do

Inventory connects your products to POS sales, stock control, barcode labels, reports, and AI analysis. POS sales can deduct stock for normal unit products and weight-based products.

When to use it

Use it when adding new products, correcting product details, importing files, or preparing labels.

Steps

  1. Open the inventory or manage store area.
  2. Add a product with name, price, category, stock, and barcode if available.
  3. Edit product details when price or stock changes.
  4. Use tombstone delete when you need to remove a product while preserving sync history.
  5. Import inventory from Excel, PDF, or AI-readable documents when supported.
  6. Generate or print barcode labels for products that need scanning.
  7. After POS sales, review stock levels and sync status so other devices receive the latest quantity.

Important tips

  • Use tombstone deletion for synced systems so old records do not reappear.
  • Review imported inventory before using it in live POS sales.
  • Check product unit type before selling weight-based items so stock deducts correctly.
  • Ask AI about low stock or product availability when your AI provider is connected.
  • If several devices sell the same inventory, sync before starting a shift and again after large sales.

Common problems

  • If a label does not print, confirm the printer, label size, and browser print settings.
  • If stock is wrong, check recent sales, imports, manual edits, and whether the sale was saved before sync.
  • If a weight product deducts incorrectly, review the product setup and unit/weight value used during the sale.
  • If a deleted product returns on another device, confirm sync completed and the delete was not done only on an offline device.

Pro Business

Use Service Tickets / Work Orders

Service Tickets / Work Orders is available for Pro Business accounts. Create job tickets for workers, mechanics, waiters, technicians or field teams, then review parts, labor, stages, invoices and reports from the owner workspace.

What this helps you do

Service Tickets turns Cayia into a per-worker job-ticket system. A mechanic, waiter, technician, supervisor or team member can create a ticket for each job, add customer details, describe the work, enter parts used, add labor, move the ticket through stages, and print a customer invoice when needed.

Service Tickets is a Pro Business standalone workflow. It does not automatically change POS sales, inventory, income, or Project Contracts. Use it when you want a clean work record that can be reviewed, printed, reported, or reconciled manually.

When to use it

Use tickets when a worker needs to record a job without giving them full access to finances or owner settings. Common examples include mechanic repair tickets, restaurant or waiter tickets, field service jobs, maintenance work, custom orders, supervisor notes, parts usage, labor tracking, and customer invoices.

Owner setup

  1. Open Settings > Business.
  2. Open the Tickets & Invoice sub-tab.
  3. Choose the business type that best matches the workflow: Mechanic Shop, Restaurant / Waiter, or Generic.
  4. Review the ticket fields shown for that business type, such as customer, vehicle, plate, VIN, work description, parts, labor, notes, stage, and technician.
  5. Configure the customer invoice design with business name, phone, address, email, website, logo, title, footer and terms.
  6. Choose which invoice fields should print, such as customer info, vehicle details, parts table, part codes, labor, technician, notes, stage and signature lines.
  7. Use the option to hide individual prices if the customer invoice should show only the final total while the internal ticket keeps full price details.
  8. Use Preview to review the invoice before workers start printing customer copies.
  9. Open Settings > Sync and use the device row Tickets or Cashiers button to add a mechanic, waiter or team member with name, password and ticket access.
  10. Open Settings > Team Access when you need to grant or edit ticket permissions such as create/view own tickets, view all members' tickets, reports, or delete tickets.

Worker workflow

  1. The team member signs in or switches to the invited workspace account.
  2. Open Tickets from the left sidebar.
  3. Choose + New Ticket.
  4. Enter the customer or job information. For mechanic mode, include vehicle details such as plate, VIN, phone or vehicle description when needed.
  5. Select routine services or common jobs from the owner-defined checkbox list when available.
  6. Add the work performed using clear language so the owner, customer and AI can understand the ticket later.
  7. Add parts used with part name, code or barcode, quantity and unit price. Cayia calculates ticket totals while you work.
  8. Add labor amount, notes, technician name or any internal detail required by the owner.
  9. Move the ticket through stages such as Estimate, In Progress and Done.
  10. Save the ticket and confirm it appears in the worker's ticket list.
  11. Print the ticket or customer invoice when the job needs a paper copy.
  12. Update the ticket if parts, labor, notes, stage or totals change before the job is finished.

Owner reports, search and AI

  • The owner can see tickets live from every approved mechanic, waiter, technician or team member.
  • Search by customer, vehicle, plate, VIN, phone, ticket number, mechanic, work description or part.
  • Filter tickets by stage, period, mechanic or team member.
  • Use the Tickets Report to group work by mechanic, see work performed, parts detail, parts vs labor subtotals, stage breakdown and grand totals.
  • Use the Parts Report to review part usage by day/time, ticket number, mechanic, vehicle, quantity, unit price and total.
  • Use part matching by name, code or both when reviewing repeated parts across tickets.
  • Use AI Advisor to ask questions such as "What parts did Victor use this week?", "How much did we bill in tickets this month?", or "Which tickets are still in progress?"
  • Ticket change history can show who edited the ticket, when it changed, what parts were added or removed, stage changes, field edits and total changes.

Important tips

  • Give each worker their own login or ticket access so reports can separate work correctly.
  • Service Tickets / Work Orders requires a Pro Business account.
  • Use consistent part names and codes so the Parts Report groups similar items correctly.
  • Service Tickets does not deduct inventory automatically. Reconcile parts with any external inventory program manually.
  • Part codes and barcodes entered in tickets are used inside Cayia ticket records and reports.
  • Workers normally see only their own tickets unless the owner grants broader access.
  • Use stage changes consistently so Estimate, In Progress and Done reports stay useful.
  • Review invoice settings before printing customer invoices for the first time.
  • Tickets sync through the approved workspace and respect the same permission isolation as the rest of Cayia.
  • If photos or CSV export are needed for tickets, check the current version notes because those capabilities may be added later.

Common problems

  • The Tickets tab is missing. Ask the owner to confirm ticket access and refresh the app after permissions are saved.
  • A worker can only see their own tickets. This is normal unless the owner grants permission to view all members' tickets.
  • The owner cannot see a new ticket. Confirm both devices are synced, the worker is in the correct workspace, and the ticket was saved.
  • Ticket totals look wrong. Review part quantity, unit price, labor amount and whether an item was added twice.
  • Parts report is grouping items incorrectly. Standardize the part name/code and choose the correct matching mode: name, code or both.
  • The customer invoice is missing a field. Open Settings > Business > Tickets & Invoice and enable the field before printing again.
  • The logo does not appear on the invoice. Re-upload or resize the logo, preview the invoice and print again.
  • AI cannot answer about every worker. Check whether the account has permission to view all tickets and whether sync is current.
  • External inventory did not change. This is expected. Service Tickets does not connect to or update external inventory systems.
  • Ticket numbers look similar across devices. Ticket numbers are for display; the internal unique ID keeps records separate.
  • A worker edited the wrong stage. Open the ticket, correct the stage and review the change history if you need to see what happened.
  • Deleting tickets is unavailable. The owner must grant delete-ticket permission, and some businesses may restrict deletion for record safety.
Pro Business

Use Project Contracts

Create project contracts, track spending, attach photos, collect payments, and monitor net profit.

What this helps you do

Project Contracts turns each job into its own control panel with contract total, estimated costs, actual expenses, client payments, budget usage, photo proof, printable reports, and AI project questions.

When to use it

Use it for remodels, service jobs, custom work, field projects, construction, repair jobs, and any project with stages or client payments.

Steps

  1. Open Project Contracts.
  2. Create a new contract and add the client name.
  3. Add the project price, estimated labor, materials, and expected margin.
  4. Divide the project into stages when you need progress tracking.
  5. Add client payments and attach photos or documents as evidence.
  6. Review financial health, expense history, budget usage, and net P&L.
  7. Open payment, receipt, or expense rows when you need to view more detail.
  8. Generate a contract or project report when ready.

Important tips

  • Project Contracts is exclusive to Master Plan / Pro Business.
  • Attach photos per stage so the project history is clear later and reports can include visual proof.
  • Use AI Project Advisor to ask about profitability, balance, materials, and pending work.
  • Owners can assign supervisors or team members to specific project responsibilities when using team/sync permissions.
  • Review newest receipts and expenses first when checking current project spending.

Common problems

  • If a project margin looks wrong, review contract total, estimated costs, actual expenses, and payments.
  • If photos do not attach, check file format, connection, file sync status, and whether temporary files were purged.
  • If a supervisor cannot see a project, confirm the user has the correct permission or assignment.
  • If a report is missing photos, run file synchronization from the device that holds the original images before generating the report.

Rent Management

Rent Management

Organize properties, units, tenants, leases, rent, fees, payments, overdue balances and rental reports inside the same ™Cayia control center used for the rest of your business.

What this helps you do

Rent Management helps landlords and property managers keep rental activity connected to the bigger financial picture. Use it to track who owes rent, what has been paid, which fees were added, which accounts are overdue, how rental income affects your dashboard and reports, and how tenants connect through the Cayia Tenants portal.

When to use it

Use this module when you manage one rental property, several units, a small apartment complex, daily rentals, or rental income alongside another business. It is especially useful when more than one person helps record payments, attach proof, or review balances from synced devices.

Steps

  1. Open Rent Management from the main navigation or from the Work area if your layout groups rental tools there.
  2. Create a property and give it a clear name, such as the street address, building name, or rental business nickname.
  3. Add units when the property has more than one rentable space, and label each unit consistently, such as Unit 1A, Apt 2, Studio B, or Daily Rental Room 3.
  4. Add the tenant or renter profile with the name, contact details, move-in date, and any notes your team needs to recognize the account.
  5. Enter lease basics, including lease start, lease end, monthly rent amount, deposit information, rent due day, and payment expectations.
  6. Register the monthly rent charge for the correct tenant, unit, date, and billing period before recording payments.
  7. Add extra charges or fees when needed, such as utilities, repairs, cleaning, parking, late fees, deposits, or other agreed charges.
  8. Record full or partial payments as they arrive, including the payment date, method, amount, and any note that explains the payment.
  9. Attach proof when available, such as a receipt image, signed note, check photo, bank confirmation, lease document, or payment screenshot.
  10. Review the balance due after every charge or payment so you can see paid amounts, remaining balance, overdue rent, and open fees.
  11. Apply late fees only after confirming the due date, grace period, local rules, and the tenant account. Add a note explaining why the fee was applied.
  12. Use reminders or alerts to follow up before and after due dates, especially for accounts with partial payments or repeated overdue balances.
  13. Check how rental income and expenses affect the dashboard, reports, and cash flow so rental activity stays aligned with the rest of your business records.
  14. Generate or review rental reports when you need a summary for the owner, tenant, accountant, property manager, or your own records.
  15. When the tenant portal is enabled, invite the tenant so they can review balance, payments, lease details, announcements, repairs, and chat from the separate portal.

Important tips

  • Use one naming pattern for all properties and units so synced teams can find the right account quickly.
  • Record charges before payments. This keeps balances, reports, and overdue status easier to understand later.
  • For partial payments, enter only the amount received and leave the remaining balance open instead of editing the original rent charge.
  • Attach proof to important payments and fees so there is a clear history if a tenant, partner, or accountant asks for details.
  • Review overdue accounts regularly and add notes after every follow-up call, message, notice, or payment promise.
  • Keep lease dates and due dates accurate because reminders, balances, late fees, and reports depend on those fields.
  • When multiple devices are synced, refresh before entering a payment and avoid two users editing the same tenant at the same time.
  • Use separate units for separate rentable spaces, even if they belong to the same property. This improves reporting and prevents mixed balances.
  • Use the Tenant Portal for renter-facing communication instead of giving tenants access to the owner app.
  • Open rental payments, receipts, or tenant rows to review detail before editing or deleting anything.

Common problems

  • The tenant balance looks too high. Review extra charges, late fees, duplicate rent entries, and partial payments before changing the balance manually.
  • A payment does not reduce the balance. Confirm the payment was saved to the correct tenant, property, unit, and billing period.
  • A late fee was applied too early. Check the rent due date, grace period, and account notes, then remove or adjust the fee if it was added by mistake.
  • The wrong tenant appears under a unit. Open the tenant profile and confirm the assigned property/unit before recording new rent or payments.
  • A property report is missing activity. Check that charges and payments were assigned to the property and not saved as general income or expenses.
  • Two devices show different balances. Confirm Cloud Sync is active, refresh both devices, and avoid editing the same tenant from two devices at once.
  • Proof attachments are missing. Check file size, connection, and whether the attachment was saved before leaving the screen.
  • Monthly rent is duplicated. Look for repeated rent charges for the same tenant and month, then keep the correct entry and remove or correct the duplicate.
  • Reminders are not appearing. Verify lease dates, rent due day, notification settings, and whether the account is marked active.
  • Dashboard totals do not match expectations. Review whether rental income, fees, payments, and property expenses were categorized consistently.
  • A tenant cannot access the portal. Confirm the tenant email, invitation status, and whether the tenant is assigned to the correct property/unit.
  • A rental payment was entered by mistake. Open the payment details, confirm it is the wrong record, then delete or correct it after the confirmation prompt.
Tenant Portal

Cayia Tenants Portal

Cayia Tenants is a separate renter-facing portal where tenants accept their rental connection, review their account, check payments and lease details, submit repair requests, read announcements, chat with the landlord, and manage portal preferences without entering the owner's main business app.

Open Tenant Portal

What this helps you do

The portal gives renters a clear dashboard for the information they usually need most: current balance, overdue months, next payment, property details, lease dates, late fees, announcements from the landlord, repair requests, photos, and chat communication.

When to use it

Use the Tenant Portal when a renter needs to check what is owed, confirm payment history, review lease information, submit a repair request, read an announcement, or message the landlord/property manager.

Main portal areas

  • Home: shows current balance, overdue status, announcements, next payment, and property summary.
  • Payments: lets tenants review payment history, amounts due, partial payments, and rent status.
  • Lease: shows lease start, lease end, monthly rent, late fees, due dates, and related lease details.
  • Repairs: lets tenants submit or follow repair and maintenance requests, including photos when available.
  • Chat: keeps tenant communication with the landlord or property manager in one place.
  • Settings: helps the tenant manage account preferences and portal access.

Steps

  1. Open the portal at https://cayia-sync-tenant.web.app/.
  2. Sign in with the same email connected to the tenant account or invitation.
  3. Accept the landlord/property manager invitation when it appears.
  4. Open Home to review current balance, overdue alerts, announcements, next payment, and property details.
  5. Use Payments to check payment history, open balances, paid amounts, late fees, and partial payments.
  6. Use Lease to review monthly rent, due date, lease start, lease end, and important agreement details.
  7. Use Repairs when the tenant needs to report a maintenance issue or follow up on a repair request.
  8. Use Chat to communicate with the landlord or property manager without mixing messages with personal texting apps.
  9. Use Settings to manage account access or preferences available to the tenant.
  10. Review landlord announcements regularly so important notices are not missed.
  11. Use Settings to choose available language/appearance preferences when supported by the portal version.
  12. If something looks wrong, contact the landlord/property manager before submitting duplicate payments or repair requests.

Important tips

  • The Tenant Portal is separate from the owner’s main Cayia business app.
  • Balances and lease details depend on what the landlord or property manager has entered in Rent Management.
  • Overdue alerts can show past months, late fees, and remaining balances.
  • Tenants should check the next payment card before assuming the account is fully current.
  • Repair requests should include clear details and, when available, photos or proof.
  • Announcements are landlord messages, such as notices, reminders, policy updates, or payment-related messages.
  • The notification bell can show portal updates such as announcements, payment notes, or other landlord activity.
  • The portal can cache some lease/account details, but fresh balances require sync with the landlord workspace.
  • If payment information looks incorrect, verify the month, amount, partial payments, and late fees with the landlord.

Common problems

  • The tenant cannot sign in. Confirm the email is the same one connected to the tenant account and reset the password if needed.
  • The balance looks wrong. Review overdue months, late fees, partial payments, and the next payment amount before contacting the landlord.
  • A payment is missing. Check whether it was applied to the correct month, property, unit, and tenant account.
  • The lease dates look incorrect. Ask the landlord/property manager to verify lease start, lease end, and monthly rent in Rent Management.
  • Repair status is not updated. Send a chat message or follow up with the landlord/property manager.
  • Announcements are not visible. Refresh the portal and confirm the tenant is signed into the correct account.
  • The tenant sees the wrong property. The landlord should verify the tenant is assigned to the correct property and unit.
  • Chat messages are delayed. Check internet connection, refresh the portal, and verify the account is still connected.
  • The invitation is pending. Ask the landlord to verify the tenant email and send or approve the connection again.
  • Repair photos do not upload. Check connection, file size, image permissions, and try again from the device that has the photo.
Users & Team

Manage users, cashiers, and permissions

Create user access for team members and control exactly what each person can see or do.

What this helps you do

Team controls help owners separate full business access from cashier, supervisor, partner, guest, project, tenant, finance, service ticket, and cash register responsibilities.

When to use it

Use Team Access when another person needs to sell in POS, submit receipts, manage assigned projects, create service tickets, help with tenant operations, review numbers, or use a synced workspace without seeing everything.

Steps

  1. Open Settings > Team Access.
  2. Create or review the user/cashier profile.
  3. Choose the role that matches the real responsibility: owner, cashier, supervisor, partner, or guest.
  4. Enable only the modules that person should use, such as POS, Dashboard, Finances, Inventory, Project Contracts, Rent Management, Service Tickets, or Cash Register. Service Tickets requires Pro Business.
  5. Remove access to sensitive areas when the person should not see totals, profit, finance history, or owner-only settings.
  6. Assign specific work scope when needed, such as project work, tenant-related tasks, or operational areas.
  7. Save the permissions and ask the user to refresh or switch to the invited workspace account.
  8. Deactivate, remove, or kick users who no longer need access.

Important tips

  • Business supports up to 3 users / cashiers.
  • Master Plan / Pro Business supports up to 7 users / cashiers.
  • Cash Register has its own permission. Existing cashiers may need it enabled by the owner.
  • Service Tickets has its own permissions for creating/viewing own tickets, viewing all members' tickets, reports, and deletion.
  • A guest can have full access or restricted access depending on what the owner allows.
  • Dashboard and Finances can be allowed or removed separately from operational access.
  • For synced guests, owner-only sync tabs are hidden. Guests normally use My Connection Account to switch workspaces.

Common problems

  • A user cannot access a feature: review plan limits, Team Access permissions, and assigned work scope.
  • A cashier cannot open Cash Register: enable the Cash Register permission for that user.
  • A worker cannot open Tickets: confirm the account is Pro Business, enable Service Tickets permission, and verify the worker is in the correct synced workspace.
  • A guest cannot see Dashboard or Finances: the owner may have intentionally removed those permissions.
  • A supervisor cannot see a project or tenant: confirm the correct project, tenant, or operational assignment.
  • A user sees the wrong account: open Settings > Synchronization > My Connection Account and switch to the invited workspace.

Synchronization

Synchronization & Cloud Sync Help

Understand how ™Cayia syncs authorized devices, team members, photos, PDFs, permissions, and temporary cloud file transfers.

What Sync is for

™Cayia uses intelligent synchronization between authorized devices and users. It is not only a backup tool. Sync helps owners share workspaces, keep teams updated, move files when needed, control permissions, sync Service Tickets, and move larger encrypted sync packages when the workspace grows.

Local firstMost business data lives on the user's device so daily work stays fast and controlled.
Temporary cloud transferCloud Sync helps move updates, photos, PDFs, attachments, and larger encrypted sync packages between approved devices.
Owner controlThe owner controls devices, team access, permissions, and original files.

Settings > Sync

Use this area when you need ™Cayia on multiple devices, when a team member needs access, when photos or PDFs must move between devices, or when you need to review sync security.

  • Sync Devices: review connected devices, users, plan limits, and license space.
  • Sync Security: review the active license, sync access, and Sync Password.
  • File Synchronization Photos & PDF: send photos, receipts, PDFs, and attachments between devices.
  • My Connection Account: switch between a personal account and an invited workspace.
  • Invite Team Member: invite guests, staff, or team members by email.
  • Ticket users: approved mechanics, waiters, technicians or team members can sync their own tickets while the owner reviews the full workspace.
  • Synchronization History: review when sync happened, which device was involved, and whether an error code needs support review.
  • Guest view: invited users with restricted access may only see My Connection Account because owner tabs are intentionally hidden.

Sync Devices

Sync Devices helps the owner understand which phones, computers, tablets, and users are connected to the workspace.

  • View connected devices and synchronized users.
  • Check device, team member, and sync connection limits for the active plan.
  • Remove old phones or computers that are no longer used.
  • Free a license slot before adding a replacement device.
  • Disconnect devices that should no longer receive business updates.

Sync Security

Sync Security is where the owner reviews the active license and manages the credentials used to protect synchronization access.

Important security warning

Keep the Sync Password secure. If the Sync Password is lost, recovery may require contacting ™Cayia support as a last option. Do not share it with users who should not control sync access.

  • Review the current Active License.
  • Change the Sync Password when access needs to be refreshed.
  • Review who should be allowed to synchronize with the workspace.
  • Update access after staff changes, lost devices, or role changes.

File Synchronization - Photos & PDF

File Synchronization moves photos, receipts, PDFs, and attachments between devices when needed. ™Cayia uses local file cache / device storage plus Firebase for temporary transfers, but the cloud is not the main permanent storage location for most files.

  • By default, original photos and PDFs live on the owner's device.
  • Cloud transfer is temporary and controlled, not a permanent document vault.
  • Other devices can download temporary copies while syncing.
  • The owner can upload existing photos, push images, share receipts, share PDFs, and update existing photos.
  • Reports may need the device to resolve images before printing or exporting, especially for contracts and rental records with photos.
  • Use Upload Existing Photos when older local images need to be shared with approved devices.
  • Use Update Existing Photos when a changed file needs to be refreshed across devices.
  • Use Purge Temporary Files or Clear All Cloud Temporary Files to remove temporary cloud copies when they are no longer needed.

My Connection Account

If multiple ™Cayia accounts are used on the same device, My Connection Account helps the user choose the correct workspace before syncing or entering data. This is also the main Sync area shown to many guest users.

  • View connected personal and invited workspace accounts.
  • Switch Account when moving between personal work and an owner's workspace.
  • Remove old accounts from the device when they are no longer needed.
  • If business data appears missing, confirm the user is inside the correct invited workspace.
  • If a guest only sees My Connection Account, that can be normal. Owner-only sync tabs are hidden from guests and cashiers.

Invite Team Member

The owner can invite team members, guests, staff, or synchronized users by email. Use the same email the teammate used to create their ™Cayia account.

  1. The teammate creates or signs in to their own ™Cayia account using their email.
  2. The owner opens Settings > Synchronization > Invite Team Member.
  3. The owner enters the same email the teammate used for their ™Cayia account.
  4. The teammate keeps ™Cayia open so the invitation can appear in their app.
  5. The teammate accepts the invitation from their app.
  6. The owner approves the accepted invitation.
  7. The owner assigns permissions from the approval flow or from Settings > Team Access.
  8. After approval, sync is active and the teammate can work inside the invited workspace according to the assigned permissions.

Synchronization History

Synchronization History helps users and owners review recent sync activity and understand whether devices are updating correctly.

  • See when synchronization happened.
  • Review which device synchronized.
  • Check cloud activity and sync timing.
  • Use the history when troubleshooting stale data or missing updates.
  • Clear history or remove old logs when the list is no longer useful.

Permissions and account switching

Guest users can switch between their personal account and the invited workspace from Settings > Synchronization > My Connection Account. If a teammate says they cannot see the owner's data, confirm they are inside the invited workspace account and not their personal account.

  • Guest access can be full access when the owner wants the teammate to help across the workspace.
  • Guest access can be restricted when the owner only wants the teammate to manage specific areas.
  • The owner can allow dashboard access or remove dashboard access.
  • The owner can allow finances access or remove finances access.
  • The owner can assign responsibilities by operational area, task, project, assigned item, or tenant-related work when configured.
  • A cashier can be limited to POS work, while a supervisor can be allowed to submit receipts, photos, or updates for assigned projects or tenant operations.

Device and team control

The owner controls synced devices from Settings > Synchronization > Synchronized Devices. From there, the owner can view synced devices and remove or kick a device that should no longer connect.

Team permissions are managed from Settings > Team Access. The owner can grant permissions, edit permissions, remove members, or kick members who should no longer have access.

Important tips

  • Business includes Cloud Sync for 3 devices.
  • Master Plan / Pro Business includes 15 devices via Cloud Sync.
  • Some plans also limit team members and sync connections, so review the plan before inviting more users.
  • Invite teammates using the exact email they use in ™Cayia.
  • Keep the Sync Password secure and update it when access should be refreshed.
  • Do not treat temporary cloud files as permanent backup. Keep important originals on the owner's device or exported records.
  • Review permissions after every role change so users do not keep old access.
  • When a teammate changes phones or computers, remove the old device before relying on the new one.
  • Do not enter the same transaction twice while waiting for sync. Refresh and confirm the active workspace first.
  • If sync shows a specific error code, copy the code before contacting support. It helps identify whether the issue is connection, encryption, file transfer, or permissions related.
  • Large sync packages may take longer. Keep the app open until the transfer finishes.

FAQ and common problems

Are my data in the cloud?

™Cayia is designed as local-first for most data. Cloud Sync helps move approved updates and temporary files between authorized devices.

What does ™Cayia keep locally?

Business records and many files are kept on the user's device. Cloud Sync is used when sharing, syncing, or transferring content to approved devices.

Are photos and PDFs stored permanently in the cloud?

No. Most photos and PDFs are not meant to live permanently in the cloud. The cloud is used for temporary transfer, and the owner can purge temporary files.

Can I use multiple accounts on one device?

Yes. Use My Connection Account to switch between a personal account and invited workspace accounts.

  • Invitation not received: keep the teammate's app open, confirm internet access, and send the invite again if needed.
  • Wrong email used: cancel or ignore the wrong invite and send a new one to the exact email used for the teammate's ™Cayia account.
  • Guest app was not open: ask the teammate to open ™Cayia, then resend or wait for the invitation to appear.
  • Owner has not approved yet: the teammate may appear pending until the owner approves and assigns permissions.
  • User appears but has no access: review Settings > Team Access because permissions may be too restrictive.
  • Guest sees personal data instead of owner workspace: switch accounts from Settings > Synchronization > My Connection Account.
  • Device needs to be reset: remove or kick the device from Synchronized Devices, then connect it again.
  • Sync appears stale: confirm Cloud Sync is active, refresh the app, and verify the user is in the correct workspace account.
  • Device limit reached: remove an old device to free a license slot, then add the new device again.
  • Photos or PDFs do not appear: run the file synchronization action again and confirm temporary files have not been purged.
  • Owner purged temporary files: upload or push the needed files again from the device that holds the originals.
  • Sync Password is lost: check secure records first. If it cannot be recovered, contact support as a last option.
  • Dashboard or finances are missing: the owner may have removed dashboard or finances permission for that guest.
  • Assigned work is missing: confirm the user is assigned to the correct project, task, item, tenant, or operational area.
  • Only My Connection Account is visible: the user is likely a guest/cashier. Owner-only tabs such as Sync Devices, File Sync, History, Security, and Invite Member are hidden by design.
  • A large sync package fails: keep the app open, check connection, copy any error code, and retry before contacting support.

Reports

Import files and export reports

Bring in PDF, CSV, or Excel files when supported, and export clean reports from ™Cayia.

What this helps you do

Reports help you review performance, share information, keep records, prepare summaries, print cash register sessions, and export project, rental, or Service Tickets activity with supporting details.

When to use it

Use reports at the end of a shift, after a project stage, before reviewing rental balances, when preparing accountant records, or when you need a printable summary.

Steps

  1. Open the report area for the module you want to export: Finance, POS, Cash Register, Service Tickets, Project Contracts, Rent Management, or another supported area.
  2. Choose PDF for a visual report or CSV for spreadsheet use when available.
  3. Select the period, category, project, tenant, cashier, register session, mechanic, ticket stage, part, or dataset.
  4. Generate the report and review it before sharing.
  5. For contract or rental reports with photos, run file synchronization first if the images live on another device.
  6. Save, download, or print the report.

Important tips

  • Review imported PDF, CSV, or Excel data before treating it as final.
  • Export regularly so you have offline records.
  • Cash Register reports are useful for shift close, drawer differences, and who opened/closed the session.
  • Service Tickets reports can group work by mechanic, stage, parts, labor and totals.
  • Project reports can include financial health and photo evidence when images are available.
  • Desktop/Windows builds may open report windows differently than a browser; allow internal report windows when prompted.

Common problems

  • If a report does not download, check browser download permissions and popup blocking.
  • If a report window does not open, allow popups for ™Cayia or retry from the Windows desktop app.
  • If photos are missing, sync or upload the files from the device that holds the originals.
  • If report totals look wrong, review the source transactions before exporting again.

Mobile & Desktop

Use ™Cayia on mobile, web, and Windows

Use Cayia in the browser, install it as a mobile web app, or run the Windows desktop version with update support.

What this helps you do

This guide helps you choose the right platform, install the app, use mobile shortcuts, avoid mobile layout issues, and understand desktop update alerts.

Steps

  1. Open the web app at https://cayia-sync-app.web.app/.
  2. On a phone, use the browser option to add the app to the home screen as a PWA when available.
  3. On mobile, use the bottom navigation for Home, Money, Add, Work, and More.
  4. Use or configure the mobile quick action shortcut for tasks like New Sale, Import Receipt, Log Income, Rent Management, or Add Tenant when permitted.
  5. When typing inside forms, let the keyboard open fully before tapping the bottom navigation again.
  6. Use the Smart Assistant toggle when the floating assistant button should be visible or hidden.
  7. On Windows, install the desktop app if you want native windows, desktop printing behavior, and update alerts.
  8. When an update pill, bell notification, or Help update panel appears, review the update and reopen the app if required.

Important tips

  • Mobile layouts are designed to avoid bottom-nav overlap, but long forms may still need scrolling before saving.
  • Quick actions depend on plan and permissions. A cashier may not see owner-only shortcuts.
  • Rental shortcuts such as Rent Management or Add Tenant appear only when the feature and permission are available.
  • Rotate tablets only when the layout benefits from extra width; phones usually work best in portrait mode.
  • If a native alert or confirmation interrupts typing, tap the input again after closing the alert.

Common problems

  • The bottom nav covers a button: scroll a little lower, close the keyboard, or reopen the form after the latest update.
  • The quick action opens the wrong place: review the selected mobile shortcut in Settings when available.
  • The app looks old after an update: refresh, clear browser cache, or reopen the Windows desktop app.
  • The keyboard stops responding after a dialog: close the dialog and tap back into the input field.
  • Printing does not work on Windows: check printer selection and whether the app has permission to open the print window.

FAQ

Frequently asked questions

Quick answers to common questions about ™Cayia, AI, sync, plans, and support.

Does ™Cayia include an API key?

No. ™Cayia uses BYOK. You connect your own API key from a compatible provider.

Are my data used to train public AI models?

™Cayia is designed around user control. AI usage depends on the provider you connect, so review your provider privacy settings and terms.

Can I use ™Cayia without AI?

Yes. Core tracking, POS, inventory, reports, and project workflows can be used without advanced AI features.

Can I use ™Cayia without internet?

Some local workflows may be available depending on the app version, but Cloud Sync, sign-in, AI, and cross-device updates require internet.

Can I use ™Cayia on multiple devices?

Yes, if your plan includes Cloud Sync. Business includes 3 devices, and Master Plan / Pro Business includes 15 devices.

Can I change plans?

Yes. Open Settings > Subscription, choose the new plan, and use Switch To [New Plan]. Stripe handles the payment update securely.

What happens if my API key fails?

AI features may stop until you update the key, provider billing, model access, or configuration.

Can I cancel my subscription?

Yes. Open Settings > Subscription and use Billing Portal or Manage Subscription. Stripe Billing Portal handles cancellation and billing changes.

Where is my information stored?

™Cayia is local-first for most business data. Cloud Sync helps share approved updates and temporary files between authorized devices when sync is active.

Can cashiers use Cash Register?

Yes, if the owner enables POS and Cash Register permission for that user.

Do Service Tickets update inventory automatically?

No. Service Tickets are standalone work records. Parts entered in tickets are used for ticket totals, invoices and reports, but inventory or external systems must be reconciled separately.

Can workers see everyone else's tickets?

Only if the owner grants that permission. By default, workers usually see their own tickets while the owner can review the full workspace.

Do guests see all sync settings?

No. Guests and cashiers may only see My Connection Account because owner-only sync tabs are hidden by design.

Can tenants use the owner app?

No. Tenants should use the separate Cayia Tenants portal for balances, lease details, repairs, chat, and announcements.

Are receipt photos and PDFs permanent cloud storage?

No. ™Cayia uses temporary cloud transfer for many files. Keep important originals on the owner device or export records.

Can AI answer questions about sales, stock, tenants, projects, or tickets?

Yes, when your AI provider is connected and the data is available, AI can help search sales, low stock, contracts, tenant balances, cash register sessions, Service Tickets, parts, labor and financial summaries.

How do I contact support?

Use the Support Center or email support@cayia.app.

Troubleshooting

Fix common issues

Use this checklist before contacting support.

  • Cannot sign in: confirm email, password, internet connection, account status, and email verification if required.
  • Data does not sync: confirm Cloud Sync is active, the device limit is not exceeded, the user is in the correct workspace, and the device is approved.
  • API key does not work: check provider billing, model access, copied key, and provider selection.
  • AI does not respond: check API key status, internet connection, provider availability, and ask a module-specific question.
  • AI answers the wrong area: mention POS, Finance, Rent Management, Project Contracts, Inventory, or Cash Register in the question.
  • Receipt scan is wrong: retake the photo with better lighting or edit the submitted receipt from Finances > Import Receipts.
  • Refund/return is wrong: open the receipt edit screen and set the refund/return checkbox correctly.
  • Inventory is missing: refresh sync, check filters, and confirm imported products were saved.
  • Stock is wrong after POS sale: review recent sales, unit/weight setup, manual edits, and whether sync finished.
  • Label does not print: verify printer, label size, browser permissions, and selected product.
  • App does not update: reload the page, clear cache, review the update alert/pill, or reopen the desktop app.
  • POS cannot find products: check product name, barcode, stock status, and filters.
  • Report does not download: allow downloads and popups for ™Cayia in the browser.
  • Cash Register is missing: ask the owner to enable the Cash Register permission in Team Access.
  • Tickets is missing: confirm the owner account is Pro Business, ask the owner to enable Service Tickets permission, and verify you are inside the correct synced workspace.
  • A ticket does not show for the owner: verify the worker saved the ticket, both devices synced, and the worker is connected to the owner workspace.
  • Ticket parts did not change inventory: this is expected. Service Tickets records parts for work orders and reports, but inventory is separate.
  • Ticket invoice is missing fields: open Settings > Business > Tickets & Invoice and enable the fields before printing again.
  • Guest cannot see sync tabs: this can be normal. Guests often only see My Connection Account.
  • Tenant Portal invitation is pending: confirm tenant email, keep the portal/app open, and ask the owner to resend or approve the invitation.
  • Mobile bottom nav covers a form: close the keyboard, scroll lower, and update/reopen the app.
  • Keyboard stops after a confirmation dialog: close the alert and tap back into the input field.
  • Photos/PDFs missing on another device: run file synchronization from the device holding the original file.
