This article explains a workaround if you collect payment on a reservation with an Expired or Closed status.
Scenario
A reservation that is created as an inquiry and is never confirmed will eventually have its status updated to Expired or Closed.
If you collect money from the guest for this reservation, the system does not create transactions in the Accounting Folio. Guesty cannot update the status of an Expired or Closed reservation.
Workaround
Since you have already collected the money, you must create a new reservation manually to have the transactions recognized in the Accounting Folio.
When creating the new reservation, record a dummy payment (e.g., cash) to reflect the transactions. This is necessary because the actual payment was received on the original reservation that is now Expired or Closed.
