The verdict in three sentences
For a group under 150 rooms, a licensed PMS at 8-15 EUR/room/month stays the rational pick: fast rollout, channel manager included, zero technical risk. Above 200 rooms across several properties, a custom PMS at 60 000-160 000 EUR pays back in 24-36 months by removing per-room fees and natively integrating your channel manager and direct booking engine. The real lever is not the software: it is the -20 % OTA commissions and +15 % RevPAR a well-run direct booking strategy delivers.
Custom vs licence: the 2026 numbers
Licence cost grows linearly with your room count, while custom is a fixed investment amortised over time. Here is the 2026 order of magnitude for a London group of 3 hotels.
| Criterion | Licensed SaaS PMS | Custom PMS |
|---|---|---|
| Upfront cost | 3 000-8 000 EUR (setup) | 60 000-160 000 EUR |
| Recurring cost | 8-15 EUR/room/month | Hosting 300-800 EUR/month |
| Annual cost at 220 rooms | 21 000-40 000 EUR/yr | 4 000-10 000 EUR/yr |
| Go-live time | 4-8 weeks | 5-9 months |
| Channel manager | Included or +150 EUR/mo | In scope |
| Customisation | Limited to options | Total |
| Data ownership | Vendor holds it | You hold it |
| Maintenance | Included | 12-18 % of cost/yr |
At 220 rooms the licence costs 21 000 to 40 000 EUR a year. Once delivered, the custom PMS drops to 4 000-10 000 EUR hosting plus 12-18 % maintenance. The 15 000-30 000 EUR annual gap repays the upfront build in 3 to 5 years, before counting commercial gains.
The modules that move RevPAR
A PMS only earns its keep if it drives performance. Here is the estimated impact of key modules on a 100-room hotel at a 120 EUR average rate.
| Module | Measured effect | Estimated annual gain |
|---|---|---|
| Direct booking engine | -20 % OTA commissions | 45 000-70 000 EUR |
| Dynamic yield management | +8 to 15 % RevPAR | 90 000-160 000 EUR |
| Real-time channel manager | -90 % overbooking | 12 000-25 000 EUR |
| Automated upselling (check-in) | +4 % basket | 18 000-30 000 EUR |
| Consolidated multi-site reporting | -1 admin FTE | 32 000-45 000 EUR |
| CRM and loyalty | +6 % repeat bookings | 25 000-40 000 EUR |
The pairing of direct booking plus yield management drives most of the return: cutting dependence on OTAs (Booking, Expedia) that charge 15-22 % commission is a structured group's first objective.
Mini case study
Take Laurent, managing director of a 3-hotel London group totalling 220 rooms. He pays a licensed PMS at 12 EUR/room/month, i.e. 31 680 EUR/yr, plus 150 EUR/month channel manager (1 800 EUR/yr). Total: 33 480 EUR/yr. His OTA commissions run on 1.9 M EUR of revenue at 18 %, i.e. 342 000 EUR/yr paid to platforms.
He invests 120 000 EUR in a custom PMS with a direct booking engine. Recurring cost: 8 000 EUR/yr (hosting + maintenance). Direct software saving: 25 480 EUR/yr. By shifting just 20 % of his OTA volume to direct booking, he saves 68 400 EUR/yr in commissions. Combined return: about 93 800 EUR/yr, paying the project back in 15 to 16 months.

FAQ
How much does a custom hotel group PMS cost in 2026?
Expect 60 000 to 160 000 EUR depending on modules (booking, channel manager, yield, CRM, billing). A 2-3 hotel group with direct booking and consolidated reporting typically lands around 90 000-130 000 EUR.
At what room count does custom become worthwhile?
Usually above 180-200 rooms. Below that, licence cost (8-15 EUR/room/month) stays lower than amortising the build. The maths also depends on the OTA commission volume you want to reclaim.
How long does a custom PMS take to deliver?
Between 5 and 9 months by scope. Budget 2-3 months for booking and channel manager, then yield, CRM and reporting modules by iteration. Migrating data from the old PMS adds 3-6 weeks.
Can we keep our existing channel manager?
Yes, via API. Many groups keep a third-party channel manager (SiteMinder, D-EDGE) connected to the custom PMS. This cuts development scope by 15-25 % and cost accordingly.
Who owns the guest data with a custom PMS?
You do. That is a decisive edge: you freely use your database for CRM, loyalty and direct marketing, without depending on a SaaS vendor's limited exports or a third party's GDPR restrictions.
