The verdict in three sentences
A vertical PMS (5-15 EUR/room/month) properly equips a standalone hotel, but a multi-site group benefits from owning its centralised platform with a direct booking engine. Budget 80,000 to 180,000 EUR for a core covering reservations, rates, yield and consolidated reporting. The calculation rests on two figures: -15 % OTA commissions and +8 to +12 % RevPAR through yield and direct sales.
Off-the-shelf PMS or custom multi-site platform
For a single hotel, a SaaS PMS is unbeatable. For a group that wants to steer rates, availability and clientele in a unified way — and stop handing 15 to 22 % to Booking and Expedia — custom changes the economic equation.
| Criterion | Vertical PMS (SaaS) | Custom platform |
|---|---|---|
| Upfront cost | 2,000 to 10,000 EUR | 80,000 to 180,000 EUR |
| Recurring cost | 5-15 EUR/room/month | Hosting 300-800 EUR/month |
| Direct booking | Standard engine + commission | Commission-free, yours |
| Yield / pricing | Paid optional module | Group-specific rules |
| Multi-site reporting | Limited | Consolidated, real-time |
| Channel manager | Often an add-on | Integrated and configurable |
| Data ownership | Partial | Full |
For a group of 4 hotels totalling 300 rooms, a PMS at 10 EUR/room/month represents 36,000 EUR/year, over 100,000 EUR across three years — without owning the engine or the guest data.
The crux: OTA commissions and RevPAR
Direct sales and yield are the two financial engines of a hotel group. Here is the 2026 order of magnitude for a 300-room group at 55 % average occupancy, 95 EUR average rate.
| Lever | 2026 situation | Estimated annual gain |
|---|---|---|
| OTA share cut from 45 % to 30 % | Average commission 18 % | 130,000 to 170,000 EUR |
| RevPAR +10 % via yield | Price adjusted to demand | 500,000 to 560,000 EUR additional revenue |
| Automated upsell (early check-in, spa) | +4 EUR/night sold | 120,000 to 150,000 EUR |
| No-show reduction (pre-authorisation) | -2 pts no-show | 60,000 to 90,000 EUR |
Mini case study
Nadia, director of a group of 4 independent hotels in Marseille (300 rooms), pays 45 % of her revenue to OTAs and manages rates hotel by hotel. She invests 145,000 EUR in a custom platform: direct booking engine, channel manager, centralised yield, consolidated reporting. Within 12 months, the direct share rises from 30 to 45 %, cutting commissions by 155,000 EUR, and RevPAR grows 9 % (460,000 EUR additional revenue, ~120,000 EUR margin). Payback in under 8 months.
FAQ

Doesn't a classic PMS already handle all this?
It handles a single hotel's operations, but rarely a group's consolidated pricing strategy or a commission-free direct booking engine. That is where custom creates value.
How much does the direct booking engine alone cost?
A direct booking engine connected to the channel manager represents 25,000 to 50,000 EUR within a global project. It pays off as soon as you recover a few points of direct share.
Can we keep Booking and Expedia?
Yes. The goal is not to cut OTAs but to rebalance the mix: keep OTAs for visibility and push direct for margin, via a channel manager that synchronises everything.
How long to deploy across several hotels?
Budget 5 to 8 months for the complete platform, with a site-by-site rollout. The first hotel can go live in 10 to 12 weeks.
What annual maintenance budget?
Between 12 and 18 % of the development cost, i.e. 18,000 to 30,000 EUR for a 150,000 EUR project, including seasonal evolutions and secure hosting.
