The verdict in three sentences
A B2B SaaS MVP costs in Berlin in 2026 between 25,000 and 70,000 EUR depending on the depth of the core feature and the number of roles. It is built in 8 to 14 weeks on a modern stack (Next.js, Supabase, Stripe) with a monthly infrastructure cost of 50 to 300 EUR at launch. The golden rule: one single core feature done really well, rather than ten done halfway.
How much an MVP costs by ambition
An MVP is not a crippled version: it is the smallest version that solves a real, paid problem. Here are the 2026 ranges for the Berlin market.
| MVP level | Scope | Timeline | Budget |
|---|---|---|---|
| Landing + waitlist | page + capture + test payment | 2 to 3 wks | 6,000 - 12,000 EUR |
| 1 core feature MVP | auth, 1 module, payment | 8 to 10 wks | 25,000 - 40,000 EUR |
| Multi-role MVP | + admin back-office, 2 roles | 10 to 12 wks | 40,000 - 55,000 EUR |
| MVP + integrations | + 1 to 2 external APIs, webhooks | 12 to 14 wks | 55,000 - 70,000 EUR |
| Add analytics / billing | dashboards, subscriptions | +3 to 4 wks | +8,000 - 15,000 EUR |
These prices include product scoping, design, development and go-live. A Stripe subscription typically charges 1.5% + 0.25 EUR per European transaction.
Infrastructure cost and milestone steering
The classic mistake is overspending before a single paying customer. Milestone steering protects your cash.
| Milestone | Goal | Cumulative budget | Infra/month |
|---|---|---|---|
| M1 - Scoping | validated specs + mockups | 4,000 - 7,000 EUR | 0 EUR |
| M2 - Core feature | one complete flow in demo | 20,000 - 35,000 EUR | 25 - 50 EUR |
| M3 - Beta customers | 3 to 5 pilot customers | 30,000 - 50,000 EUR | 50 - 150 EUR |
| M4 - Go-to-market | real payment, onboarding | 45,000 - 70,000 EUR | 150 - 300 EUR |
Each milestone is a decision gate: if M3 fails to convince 3 pilot customers, you adjust the offer before injecting the M4 budget. That is how you avoid burning 70,000 EUR on an unvalidated idea.

Mini case study
Sarah, founder of a B2B startup in Berlin, wants a compliance-tracking tool for industrial SMEs. Rather than aiming for a full suite at 120,000 EUR, she funds a 38,000 EUR MVP focused on a single feature: the automated audit checklist. In 10 weeks she lands 4 pilot customers at 290 EUR/month, or 13,920 EUR of ARR at seed stage. That traction lets her raise funds and finance the next modules without diluting too early: the MVP served as proof, not as the final product.
FAQ
What is the difference between an MVP and a prototype? A prototype is a non-functional mockup (a few thousand euros); an MVP is a real, deployable product that customers can pay for from 25,000 EUR.
How long before first revenue? With a 1-feature MVP, expect 8 to 10 weeks of build then 4 to 8 weeks to convert the first pilots.
Is Next.js/Supabase enough to scale? Yes, this stack easily handles several thousand users; you only re-architect if the product really takes off.
What if the idea does not work? Milestone steering caps the loss at 20,000 - 35,000 EUR (M2) instead of the full budget, and you keep the code and the learnings.
Can the MVP be reused as the basis for v1? Yes, a well-designed MVP is not throwaway: you enrich it module by module toward the full version.
