The verdict in three sentences
Below 150 combined rooms, a per-room cloud PMS remains the rational choice: fast go-live, no heavy capital outlay. Beyond that, once you run several brands, several currencies and consolidated reporting, a custom multi-site PMS pays for itself through rate control and license savings. The real decision is not the entry price but the cost per room over five years and your ability to drive yield centrally.
Per-room cloud or custom: the real math
An operations director must compare a vendor's recurring rent to the amortized cost of an owned platform. The rent looks modest room by room, but it climbs mechanically with the estate and is never capitalized.
| Item (2026 order of magnitude) | Cloud vendor PMS | Custom multi-site PMS |
|---|---|---|
| Cost model | 4 to 9 EUR/room/month | 120,000 to 320,000 EUR once |
| Channel manager / accounting integrations | included but rigid | 15,000 to 45,000 EUR custom |
| Annual maintenance | included in rent | 15 to 18 %/year of build |
| Time to deploy | 4 to 8 weeks | 6 to 10 months |
| Yield / brand customization | limited | total |
| Data ownership | vendor | group |
On a 600-room estate at 7 EUR/room/month, the rent is 50,400 EUR/year, or 252,000 EUR over five years without ever owning anything. A custom build at 240,000 EUR plus 17 % maintenance totals roughly 444,000 EUR over five years, but it capitalizes an asset and removes the per-room price penalty at every opening.
What triggers the move to custom
| Trigger signal | Expected quantified impact |
|---|---|
| Multi-brand group reporting | -30 % consolidation time |
| Centralized pricing policy (yield) | RevPAR +6 to 11 % |
| Multiple currencies and tax regimes | zero double accounting entry |
| Frequent property openings | near-zero marginal cost per site |
| Custom integrations (spa, F&B, CRM) | 15,000 to 45,000 EUR once |
When three of these signals are present, the per-room rent becomes a brake on growth: every acquisition adds to the recurring bill instead of diluting a fixed cost.

Mini case study
Mark, operations director of a 4-property hotel group in New York (620 rooms total), currently pays a cloud PMS at 7.50 EUR/room/month, i.e. 55,800 EUR/year. Group reporting ties up 1.5 part-time FTE on monthly consolidation. Moving to a custom platform at 250,000 EUR (integrations included) plus 42,500 EUR annual maintenance, he removes the per-room rent and cuts reporting time by two thirds. With RevPAR up just 7 % on lodging revenue of 14.2 M EUR, the gross annual gain exceeds 990,000 EUR: the investment pays back in under one fiscal year.
FAQ
How much does a custom hotel-group PMS cost in 2026? Expect 120,000 to 320,000 EUR depending on the number of brands, modules (spa, F&B, MICE) and integrations. The median for a 4-to-8 property group sits around 220,000 to 260,000 EUR.
What is the go-live timeline? Between 6 and 10 months, with a pilot on a single property from month 4. A well-scoped multi-site rollout limits risk by generalizing brand by brand.
What does the 15 to 18 % annual maintenance cover? Fixes, regulatory changes, upgrades, new-channel integration and support. On a 240,000 EUR build, that is roughly 36,000 to 43,000 EUR/year, to compare against the vendor rent avoided.
Can we keep our current channel manager? Yes: a custom connector to your channel manager and accounting costs 15,000 to 45,000 EUR depending on APIs. It avoids a big-bang and secures OTA sales during the switch.
At what estate size is custom profitable? As a rule, above 300 to 400 combined rooms, or as soon as consolidated reporting and central yield become strategic. Below that, rented cloud stays more efficient.
