PMS: what it is and why a hotel needs one

What a PMS is in plain words

A hotel management system covers everything that happens to rooms and guests, from the moment a booking arrives to checkout and cleaning. It is the front desk's workspace and, at the same time, the owner's source of data.

The core tool of a PMS is the booking calendar, where occupancy of every room, booking statuses, check-ins and checkouts are visible in a single workspace. The other sections are built around it: booking cards, the guest database, cleaning, finance and reports.

What a PMS does

• Bookings. Bookings from channels, the website and direct requests are collected in one calendar, and overlapping dates are flagged at once.
• Room inventory. Rooms, their categories, capacity and prices are described in the system, and free dates are visible without manual counting.
• Guests. Stay history, contacts and notes on every guest are saved and available for the next booking.
• Booking payments. The total, prepayment, deposit and balance due are recorded in the booking card.
• Staff. Front desk staff, housekeepers and the owner work in one system, and everyone sees their own tasks.
• Cleaning. The cleaning schedule is built from checkouts, so the front desk knows when a room will be ready for the next arrival.
• Reports. Occupancy, revenue, average rate and expenses are calculated automatically for each property and period.

PMS, channel manager and CRM: the difference

These terms are often confused because their functions overlap in modern systems.

It works best when these functions live in one program: a booking from a channel goes straight into the calendar, closes the dates on the other channels and appears in the guest database and the cleaning schedule. More about sales channels in the article “Channel manager”.

Who needs a PMS

A PMS is not only for large hotels. It already pays off in time where:

• there are more than three or four rooms and bookings come from several sources;
• at least one front desk employee or housekeeper works besides the owner;
• the property is sold on channels and on its own website at the same time;
• the owner wants to see occupancy and revenue without counting by hand in a spreadsheet.

For one or two units without staff, a booking calendar and calendar sync are often enough. Once there is a team, a full system is needed. On moving away from spreadsheets, see the article “Excel or CRM for vacation rentals”.

How to choose a hotel PMS

1. List your tasks. Which sales channels are connected, how many staff you have, whether you need a booking engine for the website and expense tracking.
2. Check channel connections. Find out which channels connect directly and which connect through calendar sync.
3. Evaluate room management. The system should manage rooms individually, group them by category and show bookings waiting for a room.
4. Check access rights. A housekeeper does not need finance, and a front desk employee does not need every property in the chain.
5. Look at mobile access. Owners and housekeepers often work from a phone.
6. Clarify accounting requirements. Guest registration, cash registers and reporting work differently in different systems, and this is worth checking before you switch.
7. Try it on your own data. Add your rooms and a few real bookings before moving all your work.

How it works in Glavbook

Glavbook combines a booking calendar, a channel manager, a booking engine, a guest database, cleaning and analytics in one system for hotels, hostels, guest houses and apartments.

• Hotel rooms appear as separate rows in a shared calendar, each with its own area, capacity and price.
• Bookings without an assigned room wait in a separate list and are allocated to free rooms once the arrival plan is clear.
• Avito connects directly, Sutochno.ru and CIAN through calendar sync. The system does not save overlapping dates and flags them as a conflict.
• The booking engine on the hotel's website shows room categories with the price for the selected dates and the number of free rooms.
• The booking card holds the total, prepayment, deposit and balance. A tentative booking without a prepayment also holds the dates and is sent to the channels.
• A guest database with stay history, ratings and a blacklist check.
• A cleaning schedule based on checkouts and a separate housekeeper workspace on the phone.
• Staff roles with access only to assigned properties; every booking change is saved with the employee's name.
• Reports on occupancy, revenue, average rate and profitability, including expenses per property.

Glavbook is currently free, with no limits on the number of properties or staff. More on the page “Hotels and hostels”.
