# Resume a payment or unfinished order

> Find an unpaid order in History, continue its payment or choose another payment method.

Reopen the existing order when a customer still needs to pay. Check its number, items and total, especially after another person or device handled payment.

## Who can do this?

**Owners, Managers and Staff** can take payments for orders in their shop.

## Where to do it

In the web app, open **History** and select the order. Actions depend on payment status. Paid, completed, cancelled or refunding orders do not offer another payment here.

## Continue the payment

1. Check that you have selected the correct shop and order.
2. If payment has not started, select **Take payment**. For an order left unpaid for later, select **Take pay later payment**. After a failed attempt, select **Retry payment**.
3. Choose QR code, payment link, SMS, cash or a registered device. **Pay later** leaves the order unpaid.
4. For cash, confirm only after receiving the money. For other methods, wait for the order to show that payment succeeded.
5. Once service is finished, mark the paid order complete.

A failed attempt may reopen its previous payment screen. Check the message there before retrying or changing the method.

## When a payment is already active

History shows the existing QR code or payment link when it is available. The customer can continue with that payment. Copying an existing link does not create another order.

Select **Change payment method** to choose another method. Before creating an SMS payment link, the app finds and expires any active link. Give the customer the latest message. After a sending error, check the order: the old link may already be disabled or the message delivered.

If the link will not load, refresh the order and check for payment elsewhere. A missing link or expired-or-cancelled message can reflect a loading error. If still unpaid, select **Create a new QR code** or **Create a new payment link**, as offered. SMS orders request the recipient’s number instead. These actions request a new link.

On the success screen, **Mark order complete** completes the order. **Skip, next order** closes without completing it; finish later in History. The large amount excludes a separate tip. Check the receipt’s tip and total-paid breakdown.

## Platform and market notes

The web steps apply in Great Britain and Germany. Device delivery can show confirmation despite failure; check the device and History before retrying. For SMS, select the country code separately and enter the national number without repeating it. Pasting a full international number can duplicate the code.

These phone-entry instructions also apply to the mobile app. Check the recipient before every send: the mobile form keeps it afterward. A sent confirmation does not prove delivery or payment. After an error, check the same order before resending.

## Resume in the mobile app

Open the existing order from the order list. An active QR payment opens its QR screen; a link or SMS payment opens the payment-link screen. Use the displayed link or QR code when available.

Back from a payment opened through the order list returns without cancelling it. **Done** returns to the register without recording payment or completing the order. From checkout, Back may instead ask you to confirm cancellation; read the prompt before confirming.

Select **Change payment method** for another method. Closing the choices does not itself cancel payment. Switching can continue even if cancelling the previous link fails, so the new screen does not prove the old payment stopped. Recheck the same order and contact Tapp support if the result is unclear before charging again.

## Troubleshooting

In the web app, reopen the order after Pay later: confirmation can appear despite a saving error. Closing the method picker leaves an existing link active. Choosing another method does not prove cancellation. Contact Tapp support if uncertain before collecting again.

Resolve any other order already being paid in Point of sale before reopening this one.

If the customer reports a charge but the order still appears unpaid, contact Tapp support with the order number before asking them to pay again.
