The verdict in three sentences
A custom PMS (Property Management System) for a multi-property group costs between 50,000 and 150,000 EUR, versus 5 to 15 EUR per room per month for SaaS. The three value engines: a channel manager that syncs Booking and Expedia without overbooking, yield management that pushes RevPAR up 5 to 12 %, and group centralisation giving a real-time view of revenue and occupancy. Above 3 properties, custom removes silos and needless commissions.
SaaS PMS or custom platform
A SaaS PMS (Mews, Cloudbeds, Opera Cloud) is enough for a single property. A group wanting to steer several hotels, pool its guest database and enforce its pricing policy quickly hits the limits of off-the-shelf. Here are the 2026 orders of magnitude.
| Option | Upfront cost | Recurring cost | Timeline | Best for |
|---|---|---|---|---|
| Single-hotel SaaS PMS | 1,000-3,000 EUR (setup) | 5-9 EUR/room/month | 3-6 weeks | 1 property |
| Multi-site SaaS PMS | 5,000-12,000 EUR | 10-15 EUR/room/month | 2-3 months | 2-4 hotels |
| Custom PMS (core) | 50,000-90,000 EUR | 12-18 % maintenance | 5-9 months | group, own rules |
| Full custom PMS | 90,000-150,000 EUR | 12-18 % maintenance | 9-15 months | > 5 hotels, advanced yield |
At 12 EUR/room/month, a 4-hotel group totalling 300 rooms pays 43,200 EUR a year in SaaS — nearly 220,000 EUR over five years, without owning the tool or the guest database.
The three RevPAR engines
Revenue per available room (RevPAR) is the king metric. Three functions pull it up.
| Lever | Mechanism | Typical 2026 gain | Impact (300-room group) |
|---|---|---|---|
| Channel manager | OTA sync, zero overbooking | +2 to 4 pts occupancy | 90,000-180,000 EUR/year |
| Yield management | Dynamic pricing by demand | +5 to 12 % RevPAR | 150,000-360,000 EUR/year |
| Direct booking | Fewer OTA commissions (15-25 %) | -3 to 5 pts commissions | 60,000-140,000 EUR/year |
| Group centralisation | Real-time steering, single guest DB | Faster decisions | hard to quantify |
These figures are estimates, 2026 orders of magnitude, for a reference RevPAR around 70-90 EUR. Channel manager and yield combine: the higher occupancy climbs, the more dynamic pricing captures value on high-demand nights.
Mini case study
Antoine runs a group of 4 hotels in Bordeaux and Biarritz, 300 rooms, average RevPAR of 82 EUR, about 8.98M EUR annual room revenue. A custom PMS at 110,000 EUR with channel manager and yield management lifts RevPAR by 8 % (+718,000 EUR of revenue) and shifts 6 points of bookings from OTAs to direct, saving ~130,000 EUR of commissions. Against an annual gain above 800,000 EUR, the investment pays back in under two months at full effect.

FAQ
What does a custom PMS for a group cost in 2026?
Budget 50,000 to 90,000 EUR for the multi-property core, and 90,000 to 150,000 EUR for a full platform with advanced yield management. Annual maintenance runs 12 to 18 % of the project.
Doesn't a SaaS PMS already do all this?
It handles a single hotel well, but bills per room and imposes its rules. For a group, SaaS multiplies costs and fragments the guest database; custom centralises steering and removes the per-room subscription.
Does the channel manager really prevent overbooking?
Yes: real-time availability sync between Booking, Expedia and direct automatically closes channels the moment a room sells. Accidental overbooking disappears, and with it compensation costs and bad reviews.
What concrete gain from yield management?
A RevPAR increase of 5 to 12 % depending on starting pricing maturity. On a group with 9M EUR of room revenue, even +8 % means over 700,000 EUR of additional revenue per year.
Can we connect accounting, door locks and the restaurant POS?
Yes: accounting interface, connected door-lock systems, F&B POS, PMS-POS and online payment are standard integrations. The real-time group view rests precisely on these connections.
