The verdict in three sentences
A London private clinic chooses between a modular HIS rented at EUR 60 to 150 per bed per month and a custom module billed once at EUR 40,000 to 90,000. Custom becomes worthwhile above 40 to 50 active beds, especially with complex insurance billing and multiple specialties. Either way, compliant health data hosting is mandatory, and automated reminders cut no-shows by 20 to 25 %, which often pays for the project.
Modular HIS or custom brick: the real comparison
A modular HIS (hospital information system) is billed per bed or per module; it covers the basics fast but is paid every month and adapts poorly to your workflows. A custom brick costs more upfront but is yours and integrates with your existing stack.
| Criterion | Modular HIS | Custom module |
|---|---|---|
| Entry cost | EUR 0 to 8,000 setup | EUR 40,000 to 90,000 |
| Recurring cost | EUR 60 to 150/bed/month | Maintenance 12 to 18 %/year |
| Time to go live | 2 to 4 months | 5 to 8 months |
| Workflow customisation | Limited | Total |
| Code ownership | No | Yes |
| Multi-insurer billing | Standard | Custom |
For a 30-bed clinic, a HIS at EUR 100/bed costs EUR 36,000 per year, or EUR 108,000 over three years. A EUR 65,000 custom module plus 15 % maintenance costs roughly EUR 94,000 over the same period.
What the budget covers and compliant hosting
Health data hosting is a legal obligation: plan a dedicated line in the operating budget.
| Item | 2026 order of magnitude | Detail |
|---|---|---|
| Booking + SMS reminders | EUR 8,000 to 18,000 | Automated reminders, waiting list |
| Electronic patient record | EUR 15,000 to 35,000 | History, prescriptions, documents |
| Billing + insurance claims | EUR 12,000 to 28,000 | Multi-insurer, top-ups, follow-ups |
| Certified compliant hosting | EUR 350 to 1,200/month | By volume and redundancy |
| Training + data migration | EUR 4,000 to 9,000 | Migrating the legacy system |
Integrations, security and things to watch
Clinic software does not live alone: it must talk to your medical hardware, your accounting and sometimes your in-house pharmacy. Neglect this and you multiply double entry, the main source of errors and wasted time. Here are the points to scope in the quote to avoid mid-project overruns.

On integrations, state whether you need a link to accounting software, a connector to partner labs or an automatic feed to a management tool. Each interface represents EUR 3,000 to 10,000 depending on complexity, and leaving it out of the initial scope makes change requests balloon. On security, beyond compliant hosting, require access traceability on records, strong authentication for staff and a tested backup plan, not just a contractual one.
Finally, migrating data from the legacy system is the most underestimated item: patient records, appointment history and insurance receivables must move without loss. Plan a dedicated acceptance phase and a representative test dataset. A botched migration can cost several weeks of delay and erode care teams' trust in the new tool from day one.
Mini case study
Thomas, director of a 35-bed private clinic in London, records a 14 % no-show rate across 4,200 monthly appointments. At an average EUR 60 lost per empty slot, that is roughly EUR 35,280 in missed revenue per month. Switching to a EUR 70,000 custom module with automated SMS reminders, he cuts no-shows to 10 %, recovering about EUR 10,080 per month. The software pays for itself in just over 7 months, before faster-billing gains.
FAQ
What is the minimum budget to start a custom project? Plan a realistic floor of EUR 40,000 for booking + records + basic billing. Below that, you are on a rented HIS or a generic non-medical tool.
How much does compliant hosting cost per month? Between EUR 350 and 1,200 per month in 2026 depending on data volume, redundancy and backup level. It is non-negotiable for health data.
How long until it is operational? A custom module takes 5 to 8 months across scoping, development, testing and data migration. A modular HIS is configured in 2 to 4 months.
Is multi-insurer billing truly manageable in custom software? Yes, and it is the strong argument: you automate follow-ups and track unpaid claims, with cash-flow gains of 10 to 20 % on collection times.
What return on investment should I expect? Between lower no-shows (20 to 25 %) and faster billing, payback is often 8 to 14 months for a 30 to 50-bed clinic.
