Why do cancelled or refunded bookings show a balance due?
Last updated: June 29, 2020
Any time the amount paid on a booking is less than the booking total, you’ll see an amount due on the Add payment button. This is determined by taking the difference between the booking total and the amount paid.

This same concept applies to cancelled and refunded bookings, including those with affiliate payments. If a booking was cancelled and a refund was given, the amount paid will now be less than the booking total, resulting in an amount due.
Adjusting the booking total
If you want to remove the amount due, you can add a line item discount on the booking for the same amount.

This will adjust the booking total to match the amount paid (in the case of a full refund, the amount paid will be $0), and the Add payment button will no longer be displayed on the booking.
