The verdict in three sentences
An MVP business web app costs between 20,000 and 50,000 EUR in 2026 for a single core feature delivered in 8 to 14 weeks. The goal is not a finished product but proof of value with real users, using as little throwaway code as possible. Every euro spent beyond that scope pushes back the day you learn whether the market actually wants your product.
Scope: MVP versus V1
The first mistake that blows a budget is confusing an MVP with a complete version 1. The MVP proves a hypothesis; V1 industrialises what worked.
| Criterion | MVP (2026) | Full V1 |
|---|---|---|
| Features | 1 core + auth | 4 to 8 modules |
| Budget | 20,000 - 50,000 EUR | 70,000 - 150,000 EUR |
| Timeline | 8 - 14 weeks | 6 - 10 months |
| Target users | 10 - 50 pilots | Broad market |
| Design | Reused sober system | Full custom |
| Automated tests | Critical paths | Broad coverage |
| Goal | Validate value | Scale up |
If a feature does not directly help test the central hypothesis, it leaves the MVP. That discipline protects the budget.
MVP cost items
With a senior day rate of 450 to 600 EUR in 2026, here is the typical breakdown for an MVP around 32,000 EUR.
| Item | Effort (days) | Estimated cost |
|---|---|---|
| Scoping & specs | 5 | 2,750 EUR |
| UX/UI design | 8 | 4,400 EUR |
| Front-end dev (Next.js) | 18 | 9,900 EUR |
| Back-end dev (Supabase/API) | 15 | 8,250 EUR |
| Integrations (payment, email) | 6 | 3,300 EUR |
| Testing & acceptance | 5 | 2,750 EUR |
| Deployment & go-live | 2 | 1,100 EUR |
The Next.js + Supabase stack cuts infrastructure costs (auth, database, storage included) and speeds up time to market: less plumbing, more business value.
What we cut to stay on budget
To stay under 50,000 EUR, we systematically defer: fine-grained roles and permissions, multilingual support, native mobile apps, advanced analytics dashboards, ERP integrations and fully custom design. These arrive in V1, once traction is proven.

Mini case study
Lucas, founder of a B2B startup in Berlin, wants to validate a compliance-tracking tool for industrial SMEs. MVP scope: document upload, one validation workflow, one notification. Budget: 31,000 EUR, timeline 11 weeks. He signs 12 paying pilots at 89 EUR/month, i.e. 1,068 EUR MRR at launch. With infra costs of 240 EUR/month, the margin funds the next iteration and proves market appetite before raising. A classic V1 cycle would have cost triple and delayed that learning by six months.
FAQ
Can an MVP become the final product?
Rarely as-is. You keep the technical foundation (stack, database) but refactor the paths that grew too fast. Expect 20 to 30% rewrite between a validated MVP and V1.
Why a single core feature?
Because testing a hypothesis needs clarity. A five-feature MVP dilutes the signal: you no longer know what creates value. One feature, one metric, one decision.
Can you go under 20,000 EUR?
Yes with no-code or a template, but you inherit technical limits and recurring licence costs. For a business platform meant to evolve, lightweight custom work is more profitable over 18 months.
What does maintenance cost after the MVP?
Budget 15 to 18% of the build cost per year, i.e. around 5,000 EUR/year for a 32,000 EUR MVP, excluding new features.
