Channel manager and Booking.com: how a hotel connects its own booking system

What a channel manager does, why a hotel reaches Booking.com through one, and when a reservation lands in the front desk's inbox instead of the calendar

A channel manager sends room availability and rates out to Booking.com and other portals and collects the reservations they take. Booking.com builds its API for Connectivity Partners, who go through onboarding on its side, so a hotel with its own website usually connects through a channel manager that is already one. An iCal calendar cannot stand in for it: the iCalendar format (RFC 5545) has no field for a price or a rate.

When a Booking.com reservation bypasses the hotel's system

SituationWhat Booking.com doesHow we prevent it
No acknowledgement within 30 minutesemails the reservation to the propertyacknowledgement goes only after the booking is saved in the calendar
A room or rate left unmappedemails the reservationwe check the mapping before launch and after every change to the offer
No rates for the months aheadexpects partners to load at least a full year of rates and availabilitywe make sure rates and availability cover the year ahead

One calendar instead of retyping

A booking from the hotel's own website is saved in its own system, and only the new availability goes to the channel manager, so the hotel pays no portal commission on guests who book direct. Once a day we compare the calendar with the channel manager to catch any drift before it turns into a double booking. In the Atrium panel that one calendar is a booking gantt with collision control. Channel manager APIs differ from one another, so we check the scope against the specific provider's documentation before we quote.
