The verdict in three sentences
A custom PMS (Property Management System) for a hotel group costs between 80,000 and 300,000 EUR (excl. VAT) in 2026 depending on the number of properties and channel manager depth. It centralises bookings, dynamic pricing and reporting across all sites, with a channel manager connected to OTAs (Booking, Expedia). The typical gain is +8 % RevPAR from pricing optimisation, paying back the investment in 12 to 24 months.
The modules of a group PMS
A generic PMS suits a standalone hotel; a group needs consolidation, centralised pricing and a shared guest master. Here are the blocks and their costs.
| Module | Key function | 2026 range (EUR excl. VAT) | Indicative time |
|---|---|---|---|
| Bookings & planning | Front desk, check-in/out, room plan | 15,000 - 40,000 | 6-10 wks |
| Channel manager | OTA sync, rate parity | 18,000 - 50,000 | 6-12 wks |
| Dynamic pricing | Yield, seasonality, occupancy | 15,000 - 45,000 | 6-10 wks |
| Group consolidation | Multi-site reporting, KPIs | 12,000 - 35,000 | 5-9 wks |
| CRM & loyalty | Single guest record, points program | 10,000 - 30,000 | 5-9 wks |
| Invoicing & accounting | Multi-property, exports | 10,000 - 28,000 | 5-8 wks |
Cost by group size and RevPAR
Budget depends on the number of properties and integrations (OTA, restaurant POS, accounting). 2026 order of magnitude.
| Group profile | Properties | Rooms | Modules | 2026 budget (EUR excl. VAT) |
|---|---|---|---|---|
| Small group | 2-3 | < 200 | Bookings, channel, reporting | 80,000 - 130,000 |
| Regional group | 4-8 | 200-600 | + yield, CRM loyalty | 140,000 - 220,000 |
| Multi-brand group | 9+ | > 600 | + full integrations | 230,000 - 300,000+ |
An 8 % RevPAR gain on a 400-room group at 90 EUR average RevPAR and 65 % occupancy represents about 680,000 EUR of extra revenue per year. Add fewer overbookings and rate-parity errors. Annual maintenance: 15 to 20 % of the project cost, plus unchanged OTA commissions.
Mini case study
Sophie, CEO of a 5-property hotel group in Marseille, juggles 5 different PMS and a third-party channel manager, with no consolidated view or coordinated pricing. Rate-parity inconsistencies cost her OTA penalties and lost revenue. A custom PMS at 180,000 EUR (excl. VAT) unifies the 5 sites, adds centralised yield and a single guest CRM. Within a year RevPAR rises 8 % across 350 rooms, about 550,000 EUR of extra revenue, plus 12 hours/week of manual reporting eliminated. ROI reached in under 12 months.
FAQ
Need a professional website?

Custom PMS or a cloud vendor (Mews, Opera)?
A cloud vendor costs 5 to 15 EUR per room per month, quickly 60,000 EUR/year for a group, with no control over the roadmap. Custom is a one-off amortised investment that fits your brands and specific processes.
Is the channel manager included?
Yes, it can be built or integrated with an existing connector. It syncs availability and rates with Booking, Expedia, Airbnb and your direct booking engine.
How long to roll out across all sites?
Budget 6 to 12 months. A pilot property can go live in 12 to 16 weeks before site-by-site roll-out.
Can we keep our direct booking engine?
Yes, or build a new integrated one. Maximising direct bookings cuts OTA commissions (15-25 %) and improves margin.
How is dynamic pricing handled?
The algorithm combines occupancy, seasonality, events and history to propose optimised rates, validated manually or applied automatically per property.
