The verdict in three sentences
A credible vertical SaaS MVP costs between 40,000 and 90,000 EUR in 2026 and ships in 3 to 5 months in Berlin. The technical foundation (authentication, multi-tenant, Stripe recurring billing, dashboard) accounts for 60-70% of the effort; the rest goes to the one domain feature that sets you apart. The golden rule: land one paying customer before industrializing, or you will burn 30-50% of the budget on features no one uses.
What a vertical SaaS MVP really covers
A vertical SaaS is not a brochure site: it is a software product with isolated customer accounts, automated billing and a dashboard. The minimum viable scope combines a reusable core with a single truly differentiating domain feature. Everything else waits for market validation.
| MVP module | Effort (days) | Estimated 2026 cost (EUR) |
|---|---|---|
| Auth + role management | 8-12 | 6,000 - 10,000 |
| Multi-tenant (shared schema) | 10-15 | 8,000 - 13,000 |
| Stripe Billing | 8-14 | 7,000 - 14,000 |
| Dashboard + reporting | 10-16 | 8,000 - 14,000 |
| Core domain feature | 15-25 | 12,000 - 25,000 |
| Onboarding + emails | 5-8 | 4,000 - 7,000 |
| MVP total | 56-90 | 45,000 - 83,000 |
These 2026 orders of magnitude assume a senior product team and an existing design system. Adding a native mobile app or ERP integrations easily doubles the budget.
Running cost up to 1,000 users
The good news: a young B2B SaaS runs cheap. As long as you stay on a shared-schema multi-tenant architecture, hosting, database and managed services fit within a controlled envelope.
| Monthly item | 100 users | 1,000 users |
|---|---|---|
| Hosting + managed DB | 80 - 150 EUR | 200 - 400 EUR |
| Stripe (transaction fees) | ~1.5% + 0.25 EUR/payment | ~1.5% + 0.25 EUR/payment |
| Transactional emails | 15 - 30 EUR | 40 - 90 EUR |
| Monitoring + logs | 20 - 50 EUR | 60 - 150 EUR |
| Total infra (excl. Stripe) | 115 - 230 EUR | 300 - 640 EUR |
Investing in heavy tooling before 200 paying customers is a classic mistake. The real cost is product evolution, not infrastructure.
Mini case study
Thomas, an accountant in Berlin, wants to build a SaaS for regulatory tracking aimed at accounting firms. Chosen MVP budget: 62,000 EUR, delivered in 4 months. He sells a subscription at 79 EUR/month per firm. With 35 firms signed in year one, he collects 35 x 79 x 12 = 33,180 EUR in annualized MRR, against infra of roughly 250 EUR/month. Operating break-even lands in year two, and full MVP payback around 26-30 months if growth holds at +5 customers/month.

FAQ
How much does a vertical SaaS MVP cost in 2026?
Between 40,000 and 90,000 EUR for a credible multi-tenant product delivered in 3-5 months. The technical core is 60-70% of the budget, the domain feature the rest.
Should you build multi-tenant from day one?
Yes, but with a shared schema: it is the best cost/isolation ratio for a young SaaS. Migrating to a dedicated database later costs 20,000-60,000 EUR, so put clean tenant keys in place immediately.
What infrastructure budget should you plan for?
Under 200-600 EUR/month up to 1,000 users on a shared architecture. The item that explodes is never infra, but product evolution (4,000-10,000 EUR/month at cruising speed).
When should you industrialize (CI/CD, monitoring, backups)?
As soon as you have paying customers, but without over-engineering. A simple pipeline and automated backups are enough before 200 customers; hardening comes with traction.
How do you avoid burning the budget?
Limit the MVP to a single core feature and land a paying customer before adding anything. That is what prevents the 30-50% of budget wasted on useless features.
