Whether it's a prepayment invoice, receipt, or an invoice, the cancellation process is the same.

One way to cancel an invoice is via the document list (either at the reservation or booking level). In the relevant folio, click on the menu next to the invoice and select "Cancellation".

The cancelled invoice will be visible both in the document list and within the folio where it was issued. Cancelling the invoice reopens the folio because its balance is no longer zero.

Another way to cancel an invoice is by reopening the folio. As mentioned, once a folio balance is set to zero with the issuance of a receipt, no additional items can be added. Reopening the folio automatically cancels the receipt, which then needs to be reissued.

In addition to reservations and bookings, invoices can also be cancelled voided from the invoice and folio lists.

If you're on the invoice list, open the menu next to the desired invoice and click “Cancellation”.

Similarly, on the folio list, you can cancel the receipt by reopening the folio. On the closed folio, open the menu and select “Reopen folio.” The receipt issued on that folio will be cancelled, and the folio will be reopened.
