CRS (Central Reservation System)

A centralized platform that manages a hotel's room inventory, rates, and availability across all distribution channels. The CRS connects to the PMS, GDS, OTAs, and the hotel's own website to ensure consistent availability and pricing.

Why it matters: The CRS is the hub that ensures rate and availability changes are reflected everywhere rooms are sold. Without a properly functioning CRS, rate parity issues, overbookings, and inventory mismatches across channels become inevitable.

Worked example: You close out a A$189 rate for New Year's Eve in the PMS at 3.40pm. The CRS pushes to eight channels; seven confirm within a minute, one queues and clears at 4.15pm. In those 35 minutes the lagging channel takes six bookings at A$189 against the A$279 you had just moved to - 6 × A$90 = A$540 gone, and two of them are non-refundable. The lag, not the pricing decision, cost the money.

Common mistake: Assuming a rate change is live everywhere the moment the CRS accepts it. Queues, mapping errors and channel-side caching all delay delivery, and the channel that lags is the one that will sell your compression night at yesterday's rate. Spot-check two or three channels after any significant move, especially before a high-demand date.
