A Hotel Management System (HMS) is a computer-based system that is used to manage the operations of a hotel or other hospitality property. It is a comprehensive system that integrates various business processes and functions, such as reservations, guest management, and housekeeping, into a single platform. HMS systems can help hotels to streamline their operations, reduce costs, improve efficiency, and make better-informed business decisions. Some of the specific features that may be included in an HMS system include booking and reservation tools, guest management tools, and revenue management tools. These systems can also provide real-time data and analytics, enabling hotels to monitor their performance and make data-driven decisions.
