Integrated accounts with pay-per-booking listings pay a commission each month for reservations from the previous month. These commissions are charged automatically during the first week of each month to the credit card on file in the dashboard.
If there's an error processing the payment, an orange banner will appear on the dashboard indicating there's a balance due. If payment isn't made by the time the next Booking Statement comes out, the account is considered past due and the pay-per-booking listings will be disabled.
