Booking.com charges commission on confirmed stays and cancellations of non-refundable bookings*.
Remember to always inform us of any other kinds of cancellations, such as guest no-shows, so that an invoice isn’t generated and you’re not charged commission.
If you’re looking for more information about cancellations, you can read this article: Can I cancel a reservation?
*Note: This is a modification we’re in the process of making for non-refundable reservations where guests are charged a cancellation fee. If partners choose to waive such fees for guests, we'll waive the commission, too.
We’re currently communicating this modification to partners in stages. Check your extranet inbox to see if it applies to your property yet. If you haven’t already received confirmation of this modification, you’ll be informed prior to the modification taking effect.
