CRS (Central Reservation System)

👉 The brain that controls your hotel’s reservations and distribution.

📘 What is a CRS?

A CRS (Central Reservation System) is a centralised platform that manages a hotel’s room availability, rates and reservations across all distribution channels.

It acts as the control centre connecting:

  • Direct booking engine
  • OTAs
  • GDS
  • Call centre
  • Corporate booking tools

The CRS ensures that inventory and pricing remain synchronised everywhere.

📊 CRS “Formula” (Operational Logic)

Not a financial formula, but its operational structure can be summarised as:

CRS = Centralised inventory + Rate management + Channel connectivity

Performance is often measured through:

  • Conversion rate
  • Direct booking share
  • Booking pace
  • Revenue per channel

✅ Why is a CRS important?

  • Centralises and synchronises availability across all channels.
  • Reduces risk of uncontrolled overbooking.
  • Improves operational efficiency.
  • Enables better control of distribution strategy.
  • Supports revenue optimisation decisions.

💡 Practical example of CRS

A guest books through the hotel website.
The CRS automatically updates room availability across OTAs and the GDS in real time, preventing double-selling.
