Any unpaid Invoices for a reservation must be cancelled before rebooking. Paid invoices are simply rebooked at the same time.

1. As long as no invoices have been sent, change the Status to "Cancelled".
2. If invoices have already been sent, create a  Rebooking invoice:
   1. Go to the  Invoices tab of the reservation.
   2. Click on  Generate rebooking invoice in the toolbar on the right. The amounts of all invoices that have not yet been paid are credited in the rebooking invoice.
   3. Assign a Spreadsheet template and  Send, Print or Export the rebooking invoice.
