Next day or later: Refunds processed after the day of the transaction take 1–5 business days to reflect, though in some cases it can take up to 14 business days depending on the customer's bank and card type.

FAQs
Standalone device
My device won't turn on
Use the charging cable that came with your device — other phone chargers may not provide enough power. Charge for at least 30 minutes before your first power-on. Hold the power button on the left-hand side for 3 seconds until the screen lights up.
I can't connect to WiFi
The device cannot connect to WiFi networks that require a browser login (like hotel or airport WiFi). Make sure you're entering the correct password. Your device also has a SIM card as a backup — if WiFi is unavailable, it will use mobile data automatically.
The app is asking for permissions — should I allow them?
Yes. Grant all permissions when prompted (camera, location, storage, and overlay). These are required for the payment app to function correctly.
What's a supervisor PIN and where do I find it?
The supervisor PIN is used by store managers to authorise refunds. You can find it in your Stitch Express dashboard — go to Devices, click the arrow next to your device, scroll down, and click Reveal PINs. If you're still having trouble, contact express-support@stitch.money.
A payment was declined — what do I do?
A declined payment is usually a decision by the customer's bank, not a problem with your device. Ask the customer to try another card. If multiple cards are declining, check your internet connection and contact support if the issue persists.
How do I send a receipt to a customer?
After a successful payment, you'll see options to print a receipt (if your device has a printer), or send via email or SMS. Tap the option you prefer and enter the customer's details.
How do I refund a transaction?
Tap Refund on the home screen, use the Filter to search by RRN (at least 6 digits from the receipt), select the transaction, and tap Refund. Enter the supervisor PIN and have the customer present their card.
Can I do a partial refund?
Yes. Follow the linked refund process (find by RRN), but enter a smaller amount than the original transaction. You'll still need the supervisor PIN and the customer's card.
I don't have the RRN — can I still refund?
Yes. Use an unlinked refund — tap Refund on the home screen, select Unlinked Refund, enter the amount, authorise with the supervisor PIN, and have the customer present their card.

My Shopify POS isn't detecting the device
Ensure both your Shopify POS device (iPad/tablet) and the payment device are on the same WiFi network. Check that the Stitch In-Person app is installed and the Pay with Stitch extension is enabled in your POS settings. Try restarting the Shopify POS app.
A payment was declined
A declined payment is usually a decision by the customer's bank. Ask the customer to try another card. If multiple cards are declining, check your internet connection and contact support if the issue persists.
Can I refund from Shopify instead of the device?
Yes. Refunds for Shopify POS transactions can only be processed from three places: the Shopify POS app, the Shopify admin, or the Sales page in your Stitch Express dashboard. They cannot be processed directly from the device.
