The verdict in three sentences
A market SaaS PMS costs 6,000 to 25,000 EUR per year per hotel depending on size and modules, with no upfront fee but a bill that rises indefinitely. A custom PMS requires 60,000 to 120,000 EUR excl. tax of development plus annual maintenance, but becomes competitive over five years as soon as you multiply properties or specific needs. The real stake goes beyond price: custom makes you the owner of your guest data, whereas SaaS hosts it with a third party.
A PMS's building blocks and their weight
A PMS is not a single block but an assembly of parts whose cost varies widely. Understanding this breakdown lets you decide what to build and what to integrate.
| Block | Role | Custom budget weight |
|---|---|---|
| Reservations & planning | Operational core | 20-25 % |
| Housekeeping | Cleaning, room status | 10-12 % |
| Billing & payment | Invoices, VAT, accounting exports | 15-18 % |
| Channel manager | OTA distribution | Often integrated (API) |
| Payment engine | Cards, mobile, deposits | 12-15 % |
| Reporting & KPIs | RevPAR, occupancy rate | 10-14 % |
| CRM & loyalty | Guest data, segments | 12-16 % |
SaaS vs custom over five years
SaaS wins on the short term and the small isolated property; custom wins on volume and duration. Here is the 2026 comparison for a group of three hotels.
| Item | SaaS PMS (3 hotels) | Custom PMS |
|---|---|---|
| Initial development | 0 EUR | 100,000 EUR excl. tax |
| Annual license | 45,000 EUR/yr | 0 EUR |
| Maintenance / hosting | Included | 16,000 EUR/yr |
| 5-year total | 225,000 EUR | 180,000 EUR |
| Data ownership | No | Yes |
| Custom evolutions | Limited | Unlimited |
Over five years, custom comes out 45,000 EUR cheaper for this profile, with the bonus of data control and evolutions.
Mini case study
Mr Fall, owner of a group of three strongly branded boutique hotels, pays 48,000 EUR/year in SaaS PMS licenses and hits a wall when trying to add a booking journey specific to his brand. A custom PMS at 105,000 EUR excl. tax with 17,000 EUR/year maintenance comes to 190,000 EUR over five years, versus 240,000 EUR in SaaS. He saves 50,000 EUR, gains ownership of his 40,000 guest records and can finally deploy an in-house loyalty program, an estimated source of +8 % repeat bookings.

When does SaaS remain the best choice?
For a single isolated hotel or a fast launch: at 6,000-12,000 EUR/year, with no upfront investment, it is unbeatable as long as you have no non-standard needs.
What does custom PMS maintenance cover?
Fixes, security updates, minor evolutions and hosting: allow 12 to 18 % of development cost per year, i.e. 12,000 to 22,000 EUR for a 100,000 EUR PMS.
Can we keep a market channel manager?
Yes, often recommended: we integrate an existing channel manager via API rather than rebuilding it, cutting the budget by 15 to 20 %.
How long to deliver a custom PMS?
Allow 6 to 10 months for a full scope, or 3 to 4 months for a first foundation (reservations, billing, payment) put into production on a pilot hotel.
Why does data ownership matter so much?
Because a CRM you own feeds your direct campaigns and loyalty without depending on a vendor: it is an asset that gains value year after year.
