In case of overpayment (ex: restaurant ticket), yo can issue payment credit.

In 'Settings/Users/Access management', enable the right : 'Authorize to create payment credit (instead of making change)'.

1/ Issue payment credit

In the payment section of the sale, select the DIV payment method, and enter the amount tendered by your customer with the payment type (should be higher than the total amount of the sale).
There is an overpayment because the remaining amount to pay is negative.
You will find a 'Create credit' button.

If you click on it, a new payment line linked to the OVPAY payment type is added to balance the amount to pay.
You can print a credit ticket for this negative payment line.

2/ Use payment credit

In the payment section of the sale, select the DIV payment method, and scan the credit ticket (or copy the credit barcode in the 'Payment' field).
An OVPAY payment line is added for the credit amount.

Payment credit is single use.

In 'Reports/End of day', payments linked to the OVPAY payment method are the overpayment movements.
Negative amounts are credit issued, and positive amounts are credit used.
