PMS (Property Management System)

A property management system, or PMS, is the operational hub for running a rental: it handles bookings, guest messaging, cleaning schedules, and the day-to-day tasks of one or more listings in one place. Where a channel manager focuses narrowly on keeping calendars synced across platforms, a PMS is broader and centers on running the operation itself.

It is a recurring software cost that tends to scale with the number of properties you manage, so it earns its keep as you grow but adds little for a single occasional listing. Treat it as a real line item in your expense plan rather than an afterthought.
