Central Reservation System (CRS): Guide for hotels

  Posted in Hotel Distribution  Last updated 7/05/2025

What is a Central Reservation System?

A Central Reservation System is a type of reservation software that is used to update and maintain hotel inventory and rate information so that hotels are able to manage guest reservations in real-time. Its definition can be simplified to its purposes of centralising data from every connected distribution channel and system, including the hotel’s property management system and booking engine. By consolidating so much data, it can also be a very useful tool for hotel managers when thinking about revenue management strategies. Here’s everything you need to know about Central Reservation Systems.

Why is a hotel Central Reservation System important?

A hotel Central Reservation System is important for keeping track of reservation data and having the appropriate information to optimise distribution for the hotel. Because the CRS transfers reservation data from the PMS/s to the distribution channels in real-time, hotels are able to reach guests across as many channels as needed. In this aspect, a Central Reservation System acts in much the same way as a channel manager. A CRS generally has more features than a standalone distribution solution, but doesn’t offer the same power and performance as an integrated hotel commerce platform.

4 advantages of a Central Reservation System

Here’s four reasons hotels will choose to use a central reservation system to improve their business.

1. It can improve customer experiences

The CRS can help hotels track patterns in guest purchasing behaviour and also record reservation data to enable the creation of guest profiles.

2. It keeps everything in one place

Trying to consolidate data from OTAs, the GDS, brick-and-mortar travel agencies, phone reservations, and more can be very tricky when done manually. The Central Reservation System ensures all this information is stored and accessible in one place, and always up-to-date.

3. It increases efficiency

Admin errors, lost data, and slow processes all cost money in the long run so it’s crucial for hoteliers to find ways that make backend operations easier and quicker. By preventing data fragmentation, the CRS saves hoteliers a lot of time, money, and effort.

4. It enables better decision making

By giving greater visibility on bookings, a Central Reservation System lets a hotel make more informed sales and pricing decisions and make more accurate performance forecasts.

How does a CRS work at a hotel?

A CRS works by collating vast amounts of data from a number of different sources into one accessible location. The CRS is able to connect the hotel’s property management system to every distribution and sales channel the hotel might be using. This ensures that all reservation data is safely recorded and stored in the hotel’s own system, meaning inventory will always be accurate and up-to-date everywhere it needs to be. The synchronisation works the other way too – the CRS can also push updated rates and availability to the distribution channels where guests are booking. For example, if you need to update a packaged rate for your hotel, you can do this within the CRS and the new rate will be reflected on your connected OTAs, your own direct booking engine, and in your PMS.

Types of central reservation systems

A Central Reservation System is just one type of reservation software. There are a number of systems on the hotel market that can help improve reservation management. Other types of reservation systems include:

  • Property Management Systems (PMS)
  • Channel Managers
  • Booking Engines

There are also many different providers of these systems, including Central Reservation Systems, and it’s up to you to decide what is the best fit for your property.
