How to install the RushFlow POS app on Android and Sunmi

Android Sunmi Updated Aug 2026

The RushFlow POS app runs on any Android phone or tablet and on Sunmi POS hardware. Because RushFlow is on the Sunmi App Store, installing it on a Sunmi device is a one-tap job and the device’s built-in receipt printer works out of the box — no third-party printing app to add.

Step by step

Connect the device to the internetPut the Sunmi device (or Android phone/tablet) on Wi-Fi or mobile data. The first sign-in needs a connection to download your catalogue; after that the app sells offline.
On a Sunmi device — open the Sunmi App StoreOn the Sunmi device, open the Sunmi App Store, search for “RushFlow”, and tap Install. Sunmi hardware is pre-trusted, so there’s nothing extra to enable.
On any Android — install from Google PlayOn a standard Android phone or tablet, install the RushFlow POS app from Google Play (or the install package provided for your business). If installing a provided package, allow installs from your file manager when prompted.
Open the app and enter your store codeLaunch the app. Enter your business store code (it identifies your business), then your cashier login and password. Tap sign in.
Let the catalogue downloadOn first sign-in the app downloads your products, prices, taxes and customers to the device. Wait for it to finish — this one-time sync is what enables offline selling afterwards.
Set up the printerGo to Settings → Printing. On Sunmi, choose the built-in printer — done. On other devices, pair a Bluetooth printer / connect USB (with OTG) / enter a network printer’s IP. Set the paper width (58mm or 80mm). See printing from the phone.
Print a test and make a test saleUse Print test to confirm the receipt, then ring up a test item and complete it — check the receipt prints and the sale appears in your reports. You’re ready to trade (including offline).

Why the Sunmi App Store listing matters

Being listed on the Sunmi App Store means RushFlow is built and tested for Sunmi hardware. The app talks to the built-in printer directly, so a shop can buy a Sunmi device, install RushFlow, and start printing receipts with no extra apps, cables or configuration.

This is a real differentiator: many POS tools need a separate printer bridge app on the same device. On Sunmi, RushFlow prints natively.

After install

Once installed and signed in, the app is ready for real trading:

Sells offline and syncs automatically — see Sell offline
Prints receipts on the built-in or paired printer
Shares stock, prices and accounts with the web and other devices
