Computer systems are increasingly important for front office operations in the hotel industry. A Property Management System (PMS) is key, as it supports reservations, guest accounting, room management, and other front and back office functions. PMS connects to other systems like Central Reservation Systems (CRS) and Global Distribution Systems (GDS) to manage reservations from different channels. Selecting a robust PMS requires analyzing hotel needs and choosing software with modules that integrate various departments and allow for growth.
