The verdict in three sentences
For a private clinic in London, a healthcare SaaS costs in 2026 between 60 and 200 EUR per user per month, while a custom-built system falls between 70,000 and 180,000 EUR to design. The decisive difference is not the entry price but the certified health-data hosting (200 to 900 EUR/month) and GDPR compliance on medical records. Below 15 users the subscription wins; beyond that, or if you want to control record interoperability, the custom build pays off over three years.
Healthcare SaaS or custom build: the 2026 orders of magnitude
The clinic management software market splits in two. SaaS vendors bill per user with fast onboarding; a custom build requires an upfront investment but removes the per-head subscription. Below are the ranges observed in London (estimate, 2026 order of magnitude).
| Item | Vendor healthcare SaaS | Custom software |
|---|---|---|
| Entry cost | 0-5,000 EUR (setup) | 70,000-180,000 EUR |
| Recurring cost | 60-200 EUR/user/month | Maintenance 12-18%/yr |
| Certified hosting | Included or +150 EUR/month | 200-900 EUR/month |
| Time to launch | 2-6 weeks | 4-8 months |
| Customization | Limited | Full |
| Records interoperability | Vendor dependent | Per specification |
| Code ownership | No | Yes |
At 15 users, a SaaS at 120 EUR costs about 21,600 EUR/year, or 64,800 EUR over three years excluding hosting. A custom build at 110,000 EUR plus 15% annual maintenance costs about 159,500 EUR over three years: the subscription stays cheaper at this volume, but the gap closes fast as headcount grows.
Health-data hosting and GDPR: the forgotten line item
Hosting health data imposes a certified health-data hosting provider. It is a regulatory constraint, not an option. The table below compares the compliance bricks to budget (2026 order of magnitude).
| Compliance brick | 2026 range | Frequency |
|---|---|---|
| Certified health-data hosting | 200-900 EUR/month | Monthly |
| Encryption and backups | 1,500-5,000 EUR | Setup |
| GDPR register + external DPO | 3,000-8,000 EUR/year | Annual |
| Security audit | 4,000-12,000 EUR | Every 2 years |
| Health-record interconnection | 6,000-15,000 EUR | Setup |
| Export anonymization | 2,000-6,000 EUR | Setup |
These costs apply whatever the model, but in a custom build they are integrated and controllable; in SaaS they depend on vendor choices you do not control.

Mini case study
Eleanor, administrative director of a 40-bed private clinic in London, manages 18 users (front desk, physicians, billing). A SaaS at 130 EUR would cost her 28,080 EUR/year, or 84,240 EUR over three years plus hosting. A custom build at 120,000 EUR with hosting at 500 EUR/month and 15% maintenance runs about 156,000 EUR over three years. The 72,000 EUR gap is justified if she wants to internalize insurance billing and record interoperability: the custom build pays off once she passes 28 users or adds a second site.
