After a "payment taken but reservation failed" alert, check your PMS before you create a reservation manually.
Why this happens. In rare cases, the PMS accepts the reservation but does not send a response back to the site in time.
- Open your PMS calendar.
- Go to the specific property and dates from the failed booking entry.
- If a booking or lead already exists for those dates, attach the payment to it rather than creating a second reservation.
- Only if nothing is there, create a new reservation manually.
