The verdict in three sentences
A hotel or restaurant group running multiple sites loses money every month on manual reconciliation of tills, PMS systems and accounting. A single software backbone — booking, payments, consolidated reporting — costs between 50,000 and 150,000 EUR in 2026 and pays back through the management time it frees up. The real question is not "vendor vs custom" but "how many sites, how heterogeneous, what level of consolidation."
What a group backbone covers in 2026
Group software is not just another PMS: it is the layer that aggregates each property's data and enforces common rules (rates, discounts, till closing, multi-rate VAT). Typical items:
| Module | Scope | 2026 order of magnitude (EUR) |
|---|---|---|
| Multi-site booking | Central engine, availability, basic yield | 12,000 - 30,000 |
| Point of sale / till | Restaurant POS, Z closing, payment methods | 10,000 - 25,000 |
| Consolidated reporting | Group dashboards, RevPAR, margin per site | 12,000 - 28,000 |
| PMS / accounting integration | Connectors, exports, reconciliation | 8,000 - 22,000 |
| Rights / data protection | Roles, audit log, partitioning | 6,000 - 15,000 |
| Testing, training, rollout | Multi-site, data migration | 8,000 - 20,000 |
A realistic timeline for such a project is 5 to 8 months, including testing and site-by-site rollout.
Vendor PMS vs custom: the real math
Market PMS platforms charge per room/month or per site; custom is an upfront investment plus fixed maintenance. For a mid-size group, the tipping point comes quickly.
| Criterion | Vendor PMS (SaaS) | Custom backbone |
|---|---|---|
| Entry cost | 0 - 8,000 EUR setup | 50,000 - 150,000 EUR |
| Recurring cost | 6 - 12 EUR / room / month | 600 - 1,800 EUR/month maintenance |
| Consolidated reporting | Often limited / optional | Custom, native |
| Group-specific rules | Vendor standard | 100% tailored |
| Data ownership | Vendor | Group |
| Reversibility | Low | Full (code delivered) |
For 300 rooms at 9 EUR/month, the vendor subscription is 32,400 EUR/year in licenses alone, excluding consolidation modules that are often billed separately. Custom becomes competitive from year 2 or 3, while delivering genuinely consolidated reporting.
Mini case study
Thomas runs a group of 5 hotel-restaurants in Greater Paris (280 rooms combined). Before the project, his management control spent 3 days per month per site consolidating tills and PMS in Excel — 15 days/month in total. He invests 92,000 EUR in a custom backbone (booking + POS + reporting), maintenance 1,200 EUR/month.
After rollout, consolidation becomes automatic: manual reporting drops by 30%, freeing the equivalent of 4.5 days/month of a controller billed at around 350 EUR/day — about 1,575 EUR/month saved. Combined with better yield oversight (estimated +2% on restaurant revenue), the project pays back in around 24 months, excluding the qualitative gain of reliable figures.

FAQ
How much does custom hotel group software cost in 2026?
Expect 50,000 to 150,000 EUR depending on site count and integrations. A group of 4 to 6 properties with consolidated reporting typically lands around 80,000 to 110,000 EUR.
Do we have to replace existing PMS systems?
Not necessarily. Many groups keep their per-site PMS and add a connected consolidation layer. That cuts the budget by 15 to 25% and reduces change-management risk.
What is the implementation timeline?
Between 5 and 8 months. The first pilot site is usually live at 3-4 months, then rollout proceeds site by site.
What should we budget for maintenance?
Maintenance runs 600 to 1,800 EUR/month depending on users and connectors, minor changes included. Major evolutions are quoted separately.
Can we integrate accounting and payment methods?
Yes: accounting exports, bank reconciliation and payment-terminal connectors are part of the backbone. It is in fact one of the biggest time-saving levers.
