Distribution
CRS
Also written: central reservation system
What CRS means
A central reservation system (CRS) is distribution software that manages a hotel brand's or chain's inventory, rates, and bookings across all sales channels. It syncs real-time room availability directly to the property management system, online travel agencies, global distribution systems, and direct booking engines.
How it is used
Revenue managers and distribution teams use a CRS to centralize rate management and inventory allocation instead of manually updating individual channels. It acts as the single source of truth for availability, enforcing rate parity and controlling room type restrictions across global markets. Operators rely on the CRS to push dynamic pricing strategies instantly, manage channel commissions, and process call-center reservations. Choosing a CRS with reliable two-way PMS integration prevents overbookings, lowers distribution costs, and optimizes the channel mix toward higher-margin direct bookings.
Worked example
A 200-room boutique hotel updates its peak-season BAR (Best Available Rate) from $200 to $250. Rather than logging into ten separate extranets, the revenue manager changes the rate once in the CRS. Within seconds, the CRS pushes the $250 rate and live room availability out to Booking.com, Expedia, Amadeus GDS, and the hotel's direct website engine simultaneously.
Common mistake
Confusing a CRS with a PMS; the CRS manages outbound distribution and reservation capture across external sales channels, whereas the PMS handles on-property operational workflows like check-ins, housekeeping, and folio billing.
