The verdict in three sentences
A custom clinic software build in Amsterdam runs between 45,000 and 110,000 EUR in 2026, versus 60 to 120 EUR per practitioner per month for a vertical SaaS licence. The budget driver is not the development itself but certified compliant hosting (350-900 EUR/month) and ongoing maintenance (900-2,500 EUR/month). For a clinic of 8 to 15 practitioners, custom becomes profitable once you factor in the 7 hours saved per week at the front desk.
Custom build vs vertical SaaS: the real trade-off
A vertical SaaS licence deploys fast but bills every practitioner every month, forever. A custom build costs more upfront but belongs to the clinic and is immune to per-user price hikes. Here are the 2026 orders of magnitude observed on the market.
| Item | Vertical SaaS | Custom build |
|---|---|---|
| Entry cost | 0-5,000 EUR | 45,000-110,000 EUR |
| Monthly cost / practitioner | 60-120 EUR | 0 EUR |
| Compliant hosting | included or +200 EUR | 350-900 EUR/month |
| Workflow customisation | limited | total |
| Code ownership | no | yes |
| Time to go live | 2-6 weeks | 14-22 weeks |
| Maintenance / upgrades | vendor package | 900-2,500 EUR/month |
For a practice under 5 practitioners, SaaS is often the right answer. Beyond 10 practitioners, stacked subscriptions catch up to the cost of a custom build within 3 to 4 years.
Optional modules and their 2026 cost
The base price covers calendar, patient record and billing. The following modules are the most requested.
| Optional module | 2026 estimate (EUR) | Expected gain |
|---|---|---|
| Patient portal (online booking) | 8,000-16,000 | -30% front-desk calls |
| Automated SMS/email reminders | 3,500-7,000 | -25% no-shows |
| Insurance billing / clearing | 9,000-18,000 | -30% rejections |
| Pharmacy / stock module | 6,000-12,000 | full traceability |
| Reporting and dashboards | 5,000-10,000 | real-time steering |
| Practitioner mobile app | 12,000-22,000 | consultation mobility |

Mini case study
Dr. Visser, director of an 11-practitioner private clinic in Amsterdam. Today he pays a vertical SaaS licence at 95 EUR/practitioner/month, i.e. 12,540 EUR/year. Over 3 years: 37,620 EUR, never owning the tool. A custom build at 78,000 EUR + hosting at 550 EUR/month + maintenance at 1,400 EUR/month comes to 78,000 + 3 years x 23,400 = 148,200 EUR over 3 years. Custom looks pricier, but the 7 hours saved weekly at the front desk (one avoided part-time FTE, ~18,000 EUR/year) and the 30% drop in billing rejections (~14,000 EUR recovered/year) bring the real extra cost close to zero from year 4, with an asset the clinic owns.
FAQ
Why is certified compliant hosting mandatory? Any personal health data hosted on behalf of a third party must sit with a certified health-data host. Budget 350-900 EUR/month on shared infrastructure in 2026, non-negotiable to stay compliant.
How long to deploy a custom build? Between 14 and 22 weeks depending on modules and integrations (clearing, national record). An MVP covering calendar and patient record can ship in 10-12 weeks.
Is maintenance really essential? Yes. Between regulatory health updates, fixes and support, maintenance at 900-2,500 EUR/month guarantees continuity. Without it, a clinic takes on compliance and downtime risk.
Can we migrate from an existing system? Yes, patient data and billing history migration costs 4,000-12,000 EUR depending on volume and export quality. Plan a prior audit.
What is the tipping point toward custom? As a rule, beyond 10 practitioners or with highly specific workflow needs (local insurers, technical platform), custom becomes financially and operationally relevant.
