# Devices and setup

## Apps and devices

Tillora runs on what you already own. We don't sell printers, scanners, card machines or tills.

> [card] The billing app
>
> A signed installer for Windows and macOS with in-app updates. The same app runs on a tablet or iPad.

> [card] The admin portal
>
> The back office opens in any browser: invoices, bills, banking, reports, tax, team and settings.

> [card] The admin app
>
> For Android and iOS: sales and dues at a glance, approve devices and purchase orders, adjust stock and share due-invoice PDFs.

> [card] Languages
>
> The admin portal is available in English, Arabic (right-to-left) and French.

## Printers, scanners and scales

Plug in the hardware that is already on your counter.

> [card] Receipt printers
>
> Any ESC/POS thermal printer, with presets for Epson, Star, Bixolon, Citizen and SNBC. Cash drawers are kicked open through the printer.

> [card] Barcode scanners
>
> Any keyboard-wedge barcode scanner.

> [card] Weighing scales
>
> Serial scales using Avery Berkel, CAS, Mettler-Toledo SICS or generic protocols.

> [card] Card machines
>
> Card machines keep working as they do today. Tillora records the payment against the bill.

> [card] A4 printers
>
> A4 invoices, and prescriptions on Tillora Desk, print on your own office printer with your letterhead.

## Working offline

A dropped connection does not stop the counter.

> [card] What keeps working
>
> Sales, payments, bills and refunds queue on the till and sync when the connection returns.

> [card] Signing in offline
>
> A cached login lasts up to 24 hours, and the app will not sign you out while unsynced sales remain.
