Summary: This guide shows how to install the Qashier POS app on a Sunmi T2, T2s or T2s Lite that you already own, log in and choose your store.
Applies to: Singapore, Malaysia, Thailand · Qashier POS on merchant-owned Sunmi devices · You need your QashierHQ login email and password.
❗️ This guide is only for your own Sunmi device. Qashier-supplied terminals (QashierX2, QashierXS, QashierXL Slim) come with Qashier POS pre-installed, and Qashier-issued payment terminals block app sideloading. See Why Can't I Install Third-Party Apps on My Qashier Payment Terminal?
Installing on another Android phone or tablet instead? See How to Install Qashier POS on Your Own Android Phone or Tablet.
Types of Sunmi POS
POS Type | Customer-facing screen? | Built-in printer? |
T2 | ❌ | ✅ |
T2s | ✅ | ✅ |
T2s Lite | ✅ | ❌ |
❗️ Important:
On the T2s and T2s Lite, the customer-facing screen is display-only. It shows the order and total to customers but is not touch-enabled.
If the Sunmi device was purchased from a previous POS vendor, the hardware may be locked, preventing the Qashier POS app from being downloaded. In such cases, you will need to purchase Qashier hardware to use our POS system.
Before you start
A Sunmi T2, T2s or T2s Lite.
A secure and stable WiFi network.
A Google account (used only to install Google Chrome).
Your Qashier login email and password, the same ones you use for QashierHQ.
Setting up your Sunmi POS to use the Qashier POS app
Step 1: On the POS, swipe left and open the Play Store app.
Swipe left to the next page of the POS
Select "Play Store"
Step 2: In the Google Play Store app, log in to your Google account.
Log in to your Google account
Step 3: Search for the "Google Chrome" app and select "Install".
Search for the Google Chrome app and select "Install"
Step 4: Sign out of your Google account once Google Chrome is installed. Open the device's Settings, go to your accounts, select your Google account and remove it.
❗️ Important: If you stay signed in, Google Play may install or update a different build of the app, and Qashier POS may not receive Qashier's updates.
💡 Tip: If you are unable to sign out of your Google account, open Google Chrome as normal. If there is a prompt to continue using Google Chrome without an account, select that option.
If you cannot sign out of your Google account, select "Use without an account" when you launch Google Chrome
Step 5: Open Google Chrome and enter qashier.com/stubdl in the address bar. The file QashierStub.apk downloads immediately. Open it to install the Qashier POS app.
Enter "qashier.com/stubdl" in the address bar
Select "Open" once QashierStub.apk has downloaded
💡 Tip: You can also find the downloaded file by tapping the three dots at the top right of Google Chrome, then "Downloads".
Tap the three dots at the top right, then "Downloads"
Tap "QashierStub.apk" to start the installation
Once the download has completed, the installation will begin automatically.
💡 Tip: If a message says "For your security, your phone is not allowed to install unknown apps from this source.", select "Settings" and toggle on "Allow from this source" so the installation can continue.
Select "Settings" if this message appears
Toggle on "Allow from this source"
After Qashier POS is installed, you can turn "Allow from this source" off again for Google Chrome. Keep the permission on for the Qashier POS app itself: it needs it to install its own updates.
Step 6: Once the installation is complete, select Login.
Select "Login"
Step 7: The App Permission Settings screen may appear. Turn on Allow running app in background, Allow storing images and Allow app notifications, then tap Done.
Turn on all three permissions, then tap Done
Step 8: The app refreshes. Select Login again, log in with your Qashier account details, then select the correct store if you have more than one. For details, see How to Log in to Qashier POS.
Select "Login"
Select the correct store (if you have more than one store) to proceed
What you should see: The Qashier POS home screen for your store. You can now begin using the Qashier POS app on your Sunmi device.
