POS

Turning your phone into a full-fledged POS

You don't need a ₹40,000 billing machine anymore. A modern Android phone plus a thermal printer is enough to run a retail counter that bills faster than legacy systems.

Barcode scanning with the phone camera

Render9's scanner works off the rear camera — no separate barcode gun. For high-volume counters, pair a Bluetooth scanner and both work side by side.

Thermal printing over Bluetooth

Any 58mm or 80mm thermal printer works. Pair once, print forever. Bills look professional, come out in under two seconds, and include GST, QR codes, and your return policy.

Offline-first billing

Counters can't wait for a flaky internet connection. Render9 queues bills offline and syncs the instant you're back online — with zero data loss.

Built-in day-end and cash reconciliation

Shift-end, hit 'Day Close'. Render9 shows cash vs. card vs. UPI vs. returns, flags the difference, and generates a signable report — the way a proper POS should.
