Your Entire Shop,
In Your Pocket.
A complete point of sale that runs entirely on one Android device. Scan a barcode, ring up the sale, print the receipt. No server, no internet, no monthly bill — even when the network is down.
Point of Sale — Search, Categories & Cart
Built for the Counter, Not the Back Office
A desktop POS ties you to a desk. QyPOS Mobile puts the register in your hand — so you can serve a customer on the floor, at the shelf, or anywhere in the shop.
Truly Offline-First
Every record is written straight to an on-device database. Power cuts, dead routers, expired internet — the register keeps working. Nothing to sync, nothing to lose.
Scan, Don't Type
Point the camera at a barcode and the item lands in the cart. Built-in barcode and QR scanning turns the slowest part of a sale into a single motion.
Thermal Printing
Send a receipt to your ESC/POS thermal printer over USB or WiFi. Live receipt preview lets the customer confirm the total before you commit.
Everything the Desktop Version Does
The same FIFO engine, ledger, and day-closing that power QyPOS on desktop — tuned for a touchscreen and running entirely on-device.

Why QyPOS Mobile
Install and Go
No server, no database admin, no Docker. Install the app, open it, and start selling. Nothing to configure first.
Your Data Is Yours
Everything sits in an on-device SQLite database. No account, no cloud, no vendor holding your customer list hostage.
Works When Power Is Out
Internet outages and dead routers do not stop a sale. The app never depends on a network round-trip to ring up an order.
Same Engine as Desktop
Shares its FIFO inventory and ledger logic with the QyPOS web version, so the numbers reconcile between counter and back office.
Thumb-Speed Checkout
Barcode scanning plus a purpose-built numeric keypad cut the average time per sale compared to typing codes by hand.
Day-End Reconciliation
Expected cash versus counted cash, with variance flagged immediately — so discrepancies are caught at close, not discovered later.
