Overview
Simple POS is a ready-to-run point-of-sale web app for small shops, cafés, bakeries and kiosks. Install it on a computer at the counter or on your own server with Node.js, then sell from any current browser on a desktop, tablet or phone.
Built for the counter
- A touch-friendly sale screen with product tiles by category, instant search and barcode scanning (any USB or Bluetooth scanner that types the code works).
- Line and whole-sale discounts, with a limit for cashiers that you set.
- Tax added at checkout or included in prices, worked out exactly once per sale.
- Cash, card or both in one payment, with the change calculated from the cash handed over. Card amounts are recorded, not processed: the customer pays on your own card terminal. The app does not connect to any payment service.
Receipts that print properly
- 80 mm receipts for thermal printers and A4 invoices, in English or Arabic, with a barcode of the receipt number for quick refund lookups.
Cash you can account for
- Register sessions with an opening float, cash in and out, and a closing count. Cashiers count blind; the app records expected cash, counted cash and the variance.
Stock, refunds and reports
- Stock goes down with every sale; deliveries, stock counts and write-offs are logged.
- Full or partial refunds, paid in cash from the drawer or recorded as a card refund (made on your card terminal), with optional restocking and a numbered refund slip.
- Sales by day, by product (with cost and margin) and by cashier (with drawer variance), all exportable to CSV.
Two roles. Managers run everything. Cashiers sell, record cash in and out, and close their own drawer.
Money done right. Every amount is stored in whole cents (or halalas, fils), with one documented rounding rule and the same calculation on screen and on the server, so totals, change and variances always add up.
The interface is fully bilingual, with a real right-to-left Arabic layout, Arabic receipts and an Arabic sample shop. Your data stays in one SQLite file on your machine; the app makes no internet calls.

Requirements
Node.js 22 or newer. Version 1.0.0 was tested on Linux (x64) and Windows (x64); its one runtime npm dependency, better-sqlite3, also ships prebuilt binaries for Windows and macOS (x64 and arm64), so no compiler or build tools are needed. Data is stored in a single SQLite file. About 30 MB of disk space after install. Fonts are bundled; the app makes no internet calls.
Compatibility
Uses standard web features of current Chrome, Edge, Firefox and Safari on desktop, tablet and phone. Tested in Chromium at 1440, 1024, 768 and 390 pixels wide in English and Arabic, and checked in Firefox and Safari's WebKit engine. Works with barcode scanners that act as a keyboard and with 80 mm thermal or A4 printers through the browser print dialog.
