PMS stands for: Property Management System. It is a local hotel administration system used for reservation, availability and occupancy management, check-in/out, images, guest profiles, report generation etc. This application is used in-house (in an individual hotel) to control the onsite property activities.
The PMS can be connected with other applications such as the hotel point-of-sale (POS) or the CRS. The interface to a CRS is an additional option in order to transfer availability, reservations and guest profile information.
Additionally, various interfaces are available to create further links to internal and external systems such as room key systems, restaurant and banquet cash registers, minibar, telephone and call centers, revenue management etc.
