Once a bill has been paid and/or finalized, it is possible to unfinalize and edit the payment method. Users may void a payment (to enter another payment type on the receipt) or void a receipt entirely (to cancel the receipt and payment amount due). 

For merchants using integrated payments, note that users must void a payment before proceeding to void a finalized receipt. For merchants using integrated payments, voiding a finalized receipt must also be completed before a batch is closed. 

Users must have permissions to edit and void a finalized receipt in order to perform the following actions. See Assigning user roles for more information. 

Voiding a payment 

Please note that a receipt cannot be Finalized when voiding the payment method. If the receipt has been finalized, a user must un-finalize the bill before proceeding to void the payment. Please note: you can only unfinalize a receipt up to a week after it was finalized.

1. Open the receipt. If the receipt has been finalized, see Opening a Finalized Receipt. 
2. On the Order screen in Restaurant POS, tap the More button.
3. Tap or swipe left on the receipt's payment amount in the detailed Payments screen. A void payment button will appear. 
4. If the receipt had been finalized, a warning message will appear at the top of the screen asking the user to unfinalize the receipt. Tap Unfinalize.
5. Tap Void payment on the detailed Payments screen and again on the confirmation pop-up window.
6. Reprocess the payment from the detailed Payments screen. See Processing payments and Using the detailed Payments screen for more information.

Voiding a finalized receipt

If a receipt has been finalized with tax applied, and a VAT (BTW) ticket has been generated and printed, you can refund and effectively cancel a bill using the Void Receipt payment type method. For information on creating this type of payment method in Restaurant Manager, see Adding a payment type. 

NOTE: This is the only method to refund or adjust a finalized order for Belgian FDM users.

1. Open the receipt that you want to refund. See Opening a Finalized Receipt.
2. On the Order screen in Restaurant POS, tap the More button.
3. Tap or swipe left on the receipt's payment amount in the detailed Payments screen. A void payment button will appear. 
4. If the receipt had been finalized, a warning message will appear at the top of the screen asking the user to unfinalize the receipt. Tap Unfinalize.
5. Tap Void payment on the detailed Payments screen and again on the confirmation pop-up window. 
6. Tap the Void receipt payment-type button.
7. If the bill was split, all split amounts will be voided. This will automatically print out a refund ticket with the previous amount in negative, canceling the previous VAT (BTW) ticket.
8. If applicable, open the table and create a new receipt by adding the order items and taking payment.
