A Property Management System (PMS) manages various tasks in a hotel like check-ins, reservations, housekeeping, and accounting. PMS software is selected based on a hotel's needs analysis and can operate on different hardware platforms. When choosing a PMS, hotels must consider the software's functionality, the hardware requirements, and how PMS workstations will be placed and aesthetically impact the hotel. An effective PMS allows real-time communication between different departments to maximize efficiency and revenue.
