A little help for your counter
Let’s get you
back to selling.
Straightforward answers for setup, printers and subscriptions.
Getting started
- Create your shop and confirm its currency. Choose carefully: currency cannot change after sales begin.
- Add products, selling prices and opening stock. Barcode, SKU and buying price are optional.
- Connect to Google Play and activate an eligible trial or monthly subscription.
- Search or scan a product at the register. Receive cash or complete payment on a separate card terminal, then record the payment.
Connect a receipt printer
Open Main menu → Printer. Shai supports one configured ESC/POS raster printer. Select your connection and 58mm or 80mm paper, then print a test receipt.
Bluetooth Classic
Turn on the printer and pair it in Android Bluetooth settings. In Shai, allow Nearby devices access when requested and select the paired printer. Your printer must support Bluetooth Classic SPP; BLE-only printers are not supported by this driver.
USB
Connect a USB printer-class device with a suitable USB host/OTG adapter. Select it in Shai and allow Android’s USB access prompt. USB serial adapters and vendor-specific printer protocols may require a different driver.
Local network / Wi-Fi
Connect the printer and Android device to the same local network. Enter the printer’s IPv4 address and raw TCP port (usually 9100). Allow local-network access if Android requests it. This connection needs the local network, not an internet connection.
The job says sent, but nothing printed
“Sent” means data was transferred, not that paper output was confirmed. Check paper, cover, power and connection first. Inspect the printer before requesting a copy to avoid accidental duplicates. A print failure does not require collecting payment again.
Compatibility depends on the specific hardware. Test your printer before relying on it during a busy shift.
Working offline
After an online Google Play purchase check, the app allows up to 7 days before reconnecting. This is a reconnect allowance, not a guaranteed subscription expiry date. Connect sooner if the app asks you to refresh access.
Keep automatic date and time enabled. If Shai asks for a check, reconnect and use Subscription → Restore purchase / Refresh access. Expiry blocks new sales; it does not hide your saved records or stop an already-prepared payment from being completed.
Subscription help
How do I cancel?
Open Google Play → Payments & subscriptions → Subscriptions → Shai POS → Cancel subscription. You can also use Google Play’s subscription page. Uninstalling Shai does not cancel billing.
How do I restore my subscription?
Use both the original Shai POS account and the Google Play account that purchased the subscription, connect to the internet, and choose Restore purchase / Refresh access. This restores selling access only, not shop records.
How do refunds work?
Refund eligibility depends on Google Play’s policies and applicable law. See Google Play’s refund guidance. Canceling a subscription does not automatically refund earlier charges.
Your account and deletion
Use Google sign-in or verified email and password. Sign-in does not back up shop records. Signing out keeps local records locked to the original account.
To delete your account, open Main menu → Account → Delete account, or use our account-deletion page without reinstalling the app. Deletion does not cancel Google Play billing or erase offline devices remotely. Recreating the same email account does not restore the original account or its purchase association.
Look after your records
The initial release stores shop data on your device and has no cloud backup. Uninstalling, clearing app storage, losing or damaging the device can permanently remove your records. Temporary held tickets clear when the app process ends.
Still need a hand?
For troubleshooting, include your app version, Android version, printer model and what happened. Never send passwords, full card details or subscription purchase tokens.
