Redeem voucher in backoffice
The guest can redeem the discount by passing the voucher to you. You then process the voucher in the back office to calculate the discount. Find the guest's reservation using the search field in the upper right corner and open this reservation or create a new reservation for the guest. Under the heading Payment Status you will find the option when you click on the three dots to redeem the voucher. Click on the Redeem Voucher button. Enter the voucher and click Redeem Voucher. Then the invoice will open and you will see at the bottom that (part of) the voucher has been paid for.
Is the amount of the reservation higher than the amount of the voucher? Then the guest must pay extra or top up the remaining amount with another voucher. Is the amount of the reservation lower than the amount of the voucher? Then the remaining credit remains outstanding. The guest can redeem this credit on a new reservation.
