The verdict in three sentences
For a group of fewer than 4 properties, a vendor PMS with channel manager remains unbeatable on cost and speed. Beyond 6 hotels or 400 rooms, custom software becomes profitable from year two thanks to centralized yield and unified group reporting. The real trade-off is not the license price but the hidden cost of non-centralization: overbooking, inconsistent rates and hours of manual reporting.
Vendor PMS vs custom platform: the 2026 comparison
The 2026 market offers two models. Vendor subscriptions (Mews, Opera Cloud, Cloudbeds) bill per room, ideal for a fast start. Custom development pools bookings, rates and guest data into a platform owned by the group.
| Criterion | Vendor PMS (subscription) | Custom platform |
|---|---|---|
| Entry cost | EUR 0 to 8,000 (setup) | EUR 60,000 to 140,000 |
| Recurring cost | EUR 5 to 15/room/month | Maintenance 8 to 12 %/year |
| Channel manager | Included / module EUR 2-4/room | Built-in (Booking, Expedia, Airbnb) |
| Multi-property yield | Limited or premium | Custom, group rules |
| Consolidated group reporting | CSV export, add-ons | Real-time dashboard |
| Data ownership | Vendor | Hotel group |
| Rollout time | 3 to 8 weeks | 14 to 24 weeks |
5-year TCO: the tipping point
Total cost of ownership reveals the reversal. For a 500-room group, the vendor subscription becomes heavier than amortized custom software around year 3-4.
| Item (500-room group) | Vendor PMS | Custom |
|---|---|---|
| Year 1 | EUR 60,000 | EUR 110,000 |
| Years 2 to 5 (cumulative) | EUR 240,000 | EUR 44,000 |
| Yield + channel modules | EUR 36,000 | included |
| 5-year TCO | EUR 336,000 | EUR 154,000 |
| Estimated occupancy gain (+3 pts) | not captured | ~+EUR 540,000 revenue |
2026 order-of-magnitude estimates, excluding vendor promotions.
Mini case study
Sophie, CEO of a 6-hotel group in Bordeaux and Biarritz (520 rooms), was juggling 6 disparate PMS systems. Monthly reporting: 3 days of work for her controller. After a custom platform at EUR 118,000, centralized yield lifted occupancy from 68 % to 72 % over one year. On a revenue per room of EUR 92 and 520 rooms, those 4 points represent roughly EUR 700,000 in additional annual revenue. Reporting dropped from 3 days to 2 hours. ROI reached in under 8 months.

How much does custom hotel software really cost in 2026?
Expect EUR 60,000 to 140,000 depending on modules (PMS, channel manager, yield, CRM, reporting). A 4-to-6 hotel group typically lands around EUR 90,000 to 120,000.
At how many hotels does custom become profitable?
Generally from 5 to 6 properties or 400 rooms. Below that, the vendor subscription stays more economical because recurring fees remain contained.
Can we keep Booking and Expedia with a custom solution?
Yes. The built-in channel manager syncs availability and rates in real time with Booking, Expedia, Airbnb and the direct booking engine, cutting overbooking to near zero.
How long to deploy across several properties?
Between 14 and 24 weeks: central core first, then hotel-by-hotel rollout. Historical data migration (bookings, guests) often takes 3 to 4 weeks.
Is maintenance included?
No, it runs 8 to 12 %/year of the initial cost, i.e. EUR 9,000 to 14,000 for a EUR 110,000 platform, covering upgrades, security and support.
