The verdict in three sentences
A vertical healthcare SaaS (€35-70/practitioner/month) goes live in 3-6 weeks and covers 80% of standard needs, at the price of rigid workflows and fields. Custom (€45,000-85,000, 4-6 months) frees compliant hosting, lab and payer integrations and removes vendor lock-in, but demands CAPEX. The crossover hinges on five criteria: number of sites, specialties, CAPEX/OPEX budget, hosting constraints and tolerance for lock-in.
Vertical vs custom: head to head
The two models don't just differ on price: they oppose on speed, flexibility and ownership. 2026 orders of magnitude.
| Criterion | Vertical SaaS | Custom |
|---|---|---|
| Entry cost | €35-70/practitioner/month | €45,000-85,000 |
| Time to launch | 3-6 weeks | 4-6 months |
| Workflow flexibility | rigid | total |
| Integrations (hosting, lab, payers) | often billed | open |
| Vendor lock-in | strong | none |
| Roadmap / evolution | imposed | controlled |
| Code and data ownership | no | yes |
In short: vertical optimizes time-to-value, custom optimizes long-term control. A multi-site group with varied specialties leans quickly toward custom; a standalone clinic with standard flows is better starting vertical.
The quantified decision grid
Use this scoring table to decide objectively. The further the total leans right, the more custom is justified.
| Factor | Favors vertical | Favors custom |
|---|---|---|
| Number of sites | 1 site | 3+ sites |
| Practitioners | < 8 | > 12 |
| Specialties / workflows | standard | atypical |
| Budget model | OPEX preferred | CAPEX possible |
| Hosting / integration constraints | light | heavy |
| Amortization horizon | < 2 years | 3-5 years |
Common financial crossover: beyond 12-15 practitioners or 3 sites, cumulative vertical subscription meets the cost of a custom build over 3 years, without its control.

Mini case study
Dr. Al Nuaimi, director of a 3-clinic group (18 practitioners) in Dubai. On vertical at €55/practitioner/month, the bill hits €990/month, i.e. €11,880/year and €35,640 over 3 years, before billed connectors (~€200/month, +€7,200). Vertical total ~ €42,840/3 years, with rigid workflows and zero ownership. A custom build at €68,000 + 18% maintenance comes to ~€104,700 over 3 years, pricier in cash but with open integrations, owned data and near-zero marginal cost to open a 4th site. At group scale over 5 years, custom becomes the rational choice.
FAQ
When is vertical still the best choice? For a single-site clinic, fewer than 8 practitioners, standard workflows and an OPEX preference. The 3-6 week launch and no CAPEX clearly win there.
Is custom riskier? It is if scope isn't framed. Split into lots (MVP then extensions) and delivered by a sprint-based team, the risk is controlled and the budget predictable.
Can we start vertical then move to custom? Yes, provided you require data portability in the SaaS contract. Without an export clause, migration is costly and delays the project.
How to manage vendor lock-in on vertical? Negotiate reversibility, standard exports and connector pricing before signing. Lock-in mostly bites when these points weren't secured upfront.
Which criterion dominates for a multi-site group? Integration freedom and data ownership. From 3 sites, cumulative vertical cost and workflow rigidity tip the balance toward custom.
