A PMS (Property Management System) is the operational backbone of a hotel. Core functions: reservations, check-in/out, folio management (the running tab of charges per guest), room status, housekeeping coordination, billing, and reporting.
Modern cloud PMS platforms — including Hotelary.ai — replace the on-premise legacy systems hotels relied on for decades. The shift is comparable to the move from desktop accounting to cloud accounting: less infrastructure, faster updates, real-time integrations with channel managers, payment gateways, and POS.
