THE CRS (Central reservation system) is a comprehensive platform where hotels can manage reservations made through different channels, such as the hotel website, online travel agencies, global distribution systems (GDS) and other sales channels. This simplifies the reservation management process and avoids the risk of overbooking or double bookings. 

Some common features of a CRS may include:

Inventory management:It allows hotels to monitor room availability and prices in real time. This ensures that only available rooms are shown on booking channels and overbooking is avoided.

Online Booking: Allows customers to make reservations directly through the hotel website. The CRS processes and confirms reservations automatically, sending a confirmation to the customer and updating inventory in real time.

Integration with distribution channels: Allows connection with online travel agencies (OTAs), GDS and other popular sales channels. This makes it easy to distribute rates and availability across multiple platforms, expanding the hotel's reach and increasing booking opportunities. 

Rate and promotion administration: Allows you to establish and manage different rates depending on the season, days of the week, length of stay or other criteria. It also makes it easy to set up special promotions and discounts. 

Reports and analysis: Provides detailed reports on booking performance, revenue generated, occupancy rates and other key indicators. This helps hotels make informed decisions and evaluate the effectiveness of their sales strategy.
