The sale of a gift voucher is recorded with an invoice for the item representing the gift voucher. When the customer redeems the voucher, the same item is entered with a negative quantity.
Manual entry
For a gift voucher sold, issue an invoice for the gift voucher item, e.g. Gift Voucher. One Brix user uses the item Personalised Glass Gift Card for this purpose.
When the customer redeems the gift voucher, manually enter the same item with a negative quantity. This cancels out the amount of the gift voucher invoice issued earlier.
Import from WooCommerce
Set up the gift voucher as an item in WooCommerce.
In the [ Items ] form, set up the gift voucher item:
as type Service,
with the account in the {{Service revenue account}} field: Advances received for multipurpose vouchers or Foreign currency advances received for multipurpose vouchers.
