The verdict in three sentences
A credible B2B SaaS MVP costs between 25,000 and 70,000 EUR in 2026, delivered in 8 to 16 weeks, with authentication, Stripe billing and one polished core feature. The mistake that kills budgets is never the day rate, it's scope: every "nice-to-have" screen delays the date you confront your product with real paying customers. An MVP is judged on its learning speed, not its feature richness.
What an MVP budget actually covers
An MVP is not a poor version of the final product: it's the minimal experience that proves a segment is ready to pay. In 2026, the standard stack (Next.js, Postgres, managed auth, Stripe Billing, Vercel deployment) reaches a billable product fast, provided you cut the surplus.
| Item | Core (essential) | Nice-to-have (phase 2) |
|---|---|---|
| Authentication & roles | 3,000-6,000 EUR | Enterprise SSO +4,000 EUR |
| Core business feature | 10,000-25,000 EUR | Secondary modules +8,000 EUR |
| Billing & subscriptions | 4,000-8,000 EUR | Multi-currency billing +3,000 EUR |
| Dashboard & analytics | 3,000-7,000 EUR | Custom reports +5,000 EUR |
| Onboarding & emails | 2,000-4,000 EUR | Advanced sequences +2,500 EUR |
| Design system & UI | 3,000-8,000 EUR | White label +6,000 EUR |
The right column must stay empty at launch. A 70,000 EUR MVP is not an MVP: it's a disguised v1 that costs you two months before the first customer feedback.
Cost per sprint and delivery rhythm
Serious agencies work in two-week sprints. Costing per sprint lets you manage cash flow and stop dead if market learning is negative.
| Sprint | Deliverable | Indicative cost |
|---|---|---|
| Sprint 0 (scoping) | Specs, mockups, architecture | 4,000-7,000 EUR |
| Sprint 1-2 | Auth, database, skeleton | 8,000-14,000 EUR |
| Sprint 3-4 | Core feature | 9,000-16,000 EUR |
| Sprint 5-6 | Billing, dashboard | 7,000-13,000 EUR |
| Sprint 7 (polish) | Tests, onboarding, go-live | 4,000-8,000 EUR |
In-house build vs agency
| Criterion | In-house team | Agency / studio |
|---|---|---|
| 4-month cost | 60,000-100,000 EUR (2 senior devs) | 25,000-70,000 EUR |
| Lead time before hire | 6-12 weeks | 1-2 weeks |
| Risk if pivot | Fixed payroll | Framework contract, can stop |
| Post-MVP upkeep | Immediate | Contract 500-1,500 EUR/month |
For a first MVP to validate, the agency almost always wins: you don't hire before proving the market.

Thomas, founder of a B2B HR startup in Bordeaux, wants to validate an interview-tracking tool. He resists the temptation of 12 features and keeps one promise: centralize interview notes. Chosen budget: 38,000 EUR, delivered in 11 weeks. With a target subscription at 79 EUR/month, he needs 41 customers to cover the build in one year. He signs 18 in three months thanks to a clickable demo, raises 250,000 EUR on that traction, and funds phase 2 without burning his personal runway. The MVP cost less than one senior developer's annual salary.
FAQ
How long for an MVP in 2026?
Expect 8 to 16 weeks depending on core-feature complexity. Under 8 weeks it's a non-billable prototype; over 16, the scope has likely overflowed.
Can you launch a SaaS for under 25,000 EUR?
Yes with no-code or an ultra-reduced scope, but technical debt slows scalability. Under 25,000 EUR, aim for proof of concept rather than a product billable to several clients.
Must billing be in the MVP?
Yes, if you want to test willingness to pay. Stripe Billing integrates for 4,000 to 8,000 EUR and turns a usage test into a real market test.
What budget after launch?
Between 500 and 1,500 EUR/month for maintenance and fixes, plus the phase 2 budget (10,000-30,000 EUR) triggered only if traction is there.
Should everything be custom-coded?
No. Auth, payment, emails and analytics rely on managed building blocks. Custom work focuses on your differentiating feature, where the value lives.
