A property management system (PMS) is a software system used by hotels to manage reservations, front desk operations, housekeeping, and other functions. A PMS handles tasks like processing reservations, tracking room availability and rates, recording guest profiles, and managing the night audit process. It integrates with other hotel systems and departments to support functions such as food and beverage management, accounting, security, and human resources. Common PMS software modules include front desk operations, reservations, housekeeping, maintenance, and accounting features.
