What a PMS does
A PMS replaces the reservation book, the room-status whiteboard and the billing spreadsheet with one shared system. The core jobs are the same at a 12-room guest house and a 300-room resort:
- Reservations and inventory — which rooms (or beds) are free on which nights, at what price, and who has booked them.
- Front desk — arrivals, check-in with guest identity details, room assignment, room moves and check-out.
- Housekeeping — which rooms are dirty, clean or inspected, and which are out of order.
- Billing — a running folio of charges, taxes and payments for every stay, plus invoices for companies billed later.
- Night audit — posting the night's room and tax charges and rolling the business date.
- Reporting — occupancy, ADR, RevPAR and revenue by day, month or segment.
PMS vs channel manager vs booking engine
The PMS holds the truth about inventory and money. A channel manager copies rates and availability out to online travel agencies and brings their bookings back. A booking engine is the booking page on the hotel's own website. Many hotels buy the three separately and connect them; bedsKey includes all three in one system. See the full comparison.
Cloud PMS vs on-premise PMS
A cloud PMS runs in a web browser and is hosted by the vendor; an on-premise PMS is installed on a server at the property. The trade-offs are covered in cloud vs on-premise PMS.
How to choose a hotel PMS
| Question to ask | Why it matters |
|---|---|
| Can two staff members ever sell the same room for the same night? | Double bookings are the most expensive PMS failure. |
| Does it handle your inventory type (rooms, dorm beds, apartments)? | Hostels need bed-level inventory; serviced apartments need long stays. |
| How are rates built: one price field, or seasons, derived rates and restrictions? | Revenue depends on pricing flexibility. |
| Does billing use exact decimal arithmetic, with taxes you can configure? | Rounding errors surface at night audit and in tax filings. |
| Who can discount, void or refund, and is every change recorded? | Permissions and an audit trail protect revenue. |
| What does onboarding include? | Setup and training decide how fast staff adopt it. |
How bedsKey approaches it
bedsKey is a cloud-hosted, multi-tenant PMS for independent hotels, resorts, hostels, guest houses, serviced apartments and small hotel groups. Overlapping bookings are blocked by a database constraint rather than application code, so two clerks can never sell the same room for the same night. Room-level and bed-level inventory share one calendar, and every open screen updates the moment a reservation, room status or folio changes.
