The verdict in three sentences
Launching a vertical SaaS in Berlin costs between 60,000 and 180,000 EUR in 2026, depending on the number of modules and the depth of integrated billing. The base includes multi-tenant architecture, recurring billing (SEPA + card) and an admin back office, delivered in 4 to 8 months. Budget a run cost of 1,500 to 6,000 EUR/month and maintenance of 15 %/year of the build cost.
Modules and budget of a vertical SaaS platform
A vertical SaaS solves a precise problem for a precise sector (pharmacies, clinics, schools, logistics). Its strength: customers ready to pay a monthly subscription because the tool is built for their trade. Budget depends directly on the number of modules shipped at launch.
| Module | Contents | 2026 cost (EUR) | Timeline |
|---|---|---|---|
| Multi-tenant base | Data isolation, plans, quotas | 22,000 - 45,000 | 6-8 wks |
| Core business feature | 1 complete sector workflow | 20,000 - 48,000 | 6-10 wks |
| Recurring billing | Subscriptions, dunning, invoices | 10,000 - 22,000 | 3-4 wks |
| Admin back office | Customer management, support, metrics | 8,000 - 18,000 | 2-3 wks |
| Customer portal + roles | Onboarding, invites, permissions | 8,000 - 20,000 | 2-4 wks |
| Mobile app / PWA | Installable mobile version | 12,000 - 32,000 | 4-6 wks |
A serious vertical MVP starts at 60,000 EUR (base + 1 module + billing). The 180,000 EUR figure corresponds to a multi-module platform with a mobile app.
Run cost, maintenance and break-even in subscribers
The SaaS model only turns profitable on recurring revenue. You must calculate the break-even: how many paying subscribers cover the run and maintenance, then amortise the build.
| Item | 2026 estimate (EUR) | Frequency |
|---|---|---|
| Run infra (cloud, DB, email) | 1,500 - 6,000 | monthly |
| Maintenance (15 %/yr of build) | 750 - 2,250 | monthly |
| Payment fees | 1.5-2.9 % of volume | per transaction |
| Customer support | 1,500 - 5,000 | monthly |
| Acquisition marketing | 3,000 - 10,000 | monthly |
With an average subscription of 120 EUR/month and fixed costs of 8,000 EUR/month, operating break-even sits around 70 subscribers. To amortise a 90,000 EUR build over 24 months, you need roughly 110 active subscribers.

FAQ
What is the minimum budget to launch a vertical SaaS in Berlin? Budget 60,000 EUR for a multi-tenant base + 1 business module + billing. Below that you get an internal tool, not a commercial product.
How long to go live? Between 4 and 8 months depending on module count. A single-module vertical MVP ships in 4 months; a multi-module platform with a mobile app takes 7 to 8 months.
Do I need integrated billing from day one? Yes. Without frictionless recurring billing (SEPA + card), subscription conversion collapses. Budget 10,000 to 22,000 EUR for this integration.
How many subscribers to be profitable? With an average subscription of 120 EUR/month, operating break-even lands around 70 subscribers, and build amortisation around 110 active subscribers over 24 months.
What is the annual maintenance cost? Around 15 %/year of build cost, i.e. 9,000 to 27,000 EUR per year for a 60-180K EUR build, excluding infra run.
