Hotel PMS glossary

What is a hotel channel manager?

In short: A hotel channel manager is software that keeps rates and availability in sync across the booking channels a property sells through, such as online travel agencies, and brings the reservations those channels take back into the property management system. It exists so one room is not sold twice on two websites.

How a channel manager works

  1. Mapping — each room type and rate plan in the PMS is matched to the channel's own codes.
  2. ARI out — when availability, rates or restrictions change for a night, the update is pushed to every connected channel.
  3. Reservations in — new bookings, modifications and cancellations from channels arrive in the PMS as real reservations and reduce availability everywhere else.
  4. Confirmation — the channel acknowledges each message, so failures can be seen and retried.

Features that matter

Feature Why it matters
Per-channel pricing Sell the same plan at different prices where contracts allow
Safe retries A repeated message must never create a second booking
Overbooking handling A booking that does not fit should wait for a decision, not disappear
Delivery visibility See what each channel confirmed and what failed, and why
Parity checking Compare channel bookings against the rate each channel was sent

Channel manager vs PMS

The PMS is the source of truth for inventory, guests and money; the channel manager distributes that truth. When they are separate products, the link between them is a common source of errors. See PMS vs channel manager vs booking engine.

How bedsKey's channel manager works

The channel manager is built into bedsKey. Every changed night is pushed at that channel's price, as far ahead as you choose; bookings, changes and cancellations arrive as real reservations, and a retry never books twice. It speaks the published OpenTravel (OTA) XML message set, with channel adapters built. Room-type and rate-plan mapping can be bulk-pasted and is validated before it applies, every channel booking is compared against the rate that channel was sent, and a booking that does not fit waits on an overbooking queue. A connection cannot go live until its test against the channel's own sandbox is recorded. bedsKey’s channel manager has certified OTA connections.

Channel manager: common questions

Do I need a channel manager if I only sell on one OTA?

With a single channel you can manage availability by hand, but every booking still has to be copied into the PMS. A channel manager becomes essential once two or more channels sell the same rooms.

What causes overbooking with a channel manager?

Usually delays or failures in syncing: a room sold on one channel before the update reaches another. Fast updates, safe retries and a queue for bookings that do not fit reduce the risk.

Is bedsKey's channel manager connected to Booking.com or Expedia?

Yes. bedsKey’s channel manager has certified OTA connections, built on Booking.com’s Connectivity API and OpenTravel XML, and each connection is sandbox-tested before it goes live.
