The verdict in three sentences
An Amsterdam group practice can equip itself via a vendor solution at EUR 30 to 80 per practitioner per month, or via a custom module of EUR 25,000 to 55,000. Custom is justified as soon as you want a finely configured shared calendar and teleconsultation on your own rules. The main gain is concrete: +10 % schedule fill rate and real care coordination across the 8 practitioners.
Vendor or custom: what a group practice pays
With 8 doctors, the vendor subscription climbs fast; custom becomes an asset you control.
| Criterion | Vendor solution | Custom module |
|---|---|---|
| Entry cost | EUR 0 to 5,000 | EUR 25,000 to 55,000 |
| Monthly cost | EUR 30 to 80/practitioner | Maintenance 12 to 15 %/year |
| 8 doctors over 3 years | EUR 8,640 to 23,040 | One investment + maintenance |
| Shared calendar | Standard | Fine rules per doctor |
| Teleconsultation | Often a paid add-on | Natively built in |
| Data ownership | Partial | Total |
At EUR 55 per practitioner, 8 doctors cost EUR 5,280 per year, or EUR 15,840 over three years, excluding add-ons. A EUR 40,000 custom build plus 13 % maintenance runs about EUR 55,600 over three years but then remains your property.
Budget breakdown of a custom module
| Item | 2026 order of magnitude | Detail |
|---|---|---|
| Multi-doctor shared calendar | EUR 8,000 to 16,000 | Per-doctor rules, rooms, slots |
| Shared medical record | EUR 9,000 to 20,000 | Secure access, common history |
| Teleconsultation module | EUR 6,000 to 12,000 | Video, prescription, payment |
| Billing + claim submission | EUR 5,000 to 11,000 | Care sheets, tracking |
| Team training | EUR 3,000 to 6,000 | 8 doctors + front desk |
Interoperability, front desk and adoption
In a group practice, software success rests as much on adoption by doctors and front desk as on the technology. A poorly accepted shared calendar loses its value: you need clear per-doctor rules, nuanced access rights to records and ergonomics that save time from the first week, not the opposite.
Think interoperability: link to secure health messaging, export to the practice accounting, claim-submission connector. Each of these bricks avoids re-entry that, with 8 doctors, quickly adds up to several hours per day combined. The front desk is the first beneficiary or the first victim: involve it from scoping to validate booking, follow-up and billing flows.

Finally, budget training and go-live support seriously. Plan EUR 3,000 to 6,000 to train the 8 doctors and the admin team, plus a few weeks of close support. That is what turns good software into real fill-rate gains: without adoption, the targeted 10 % of extra slots stay theoretical and payback recedes.
Mini case study
Dr Nadia Fournier coordinates an 8-doctor practice in Amsterdam. Their schedule fill rate caps at 78 %, against a potential of 9,600 monthly slots valued at EUR 28 average net margin. Moving to 86 % fill through a pooled calendar and a smart waiting list means 768 extra slots, roughly EUR 21,504 of margin per month. A EUR 45,000 custom module pays for itself in just over two months of added gains.
FAQ
How much for an 8-doctor practice? Custom runs EUR 25,000 to 55,000 depending on calendar and teleconsultation depth. Vendor is EUR 30 to 80 per practitioner per month, or EUR 2,880 to 7,680 per year.
Is teleconsultation included? In custom, it is natively built in for EUR 6,000 to 12,000. With vendors, it is often a paid add-on billed per practitioner.
What is the setup timeline? Plan 4 to 6 months for a full custom module with shared calendar, records and billing. Migrating data from the legacy tool weighs heavily on the schedule.
How do you gain 10 % fill rate? Through the pooled calendar, reminders and a waiting list that automatically rebooks freed slots. For an active practice, that is several hundred consultations per month.
Is custom worthwhile versus subscription? Above 6 to 8 practitioners over 3 to 4 years, yes: the subscription often exceeds the cost of a module you own and can evolve.
