If you are an agency, you are likely to have owners and/or housekeepers of the properties you may wish to notify when you’ve received or cancelled a booking. This article explains at which point the owner notification is sent;
Telephone Bookings: you are asked at the end of the booking process with a tick box.
Online Bookings: the owner and housekeeping notifications are never automatically sent. You will check the booking is OK, proceed to the bookings list, click on the booking and click the notify owner or housekeeping button.
