How do I correct an invoice?

You are in the invoice of a reservation (How do I open a guest invoice?), and would like to correct an already completed and paid bill again, e.g. because the payment method was entered incorrectly or the billing address is not correct.

You can identify a closed invoice by the lock symbol  in the invoice window on the right. Click the lock symbol to reopen the invoice.

Through this process, three things happen in the background:

1. The bill is reopened for editing. Furthermore, the invoice address can be corrected and new services/items can be booked on to the invoice.
2. The invoice will be removed from the document archive.
3. The payment status is corrected internally and, as such, the bill is once again open and pending payment.
