Booking.com works by sending you an invoice for the previous month at the beginning of each month. The amount of the commission on the invoices is calculated based on the date of check-out of the guest. During the first week of the month, an invoice is issued for all bookings with the check-out date in the previous month. Payment must be made within 14 days of the invoice date. In case the guest does not come, you will not have to pay a commission if you decide to cancel the fee and mark the reservation as not appearing in the extranet or in the Pulse application.
