The verdict in three sentences
A credible B2B SaaS MVP costs in 2026 between 25,000 and 70,000 EUR (roughly USD 27,000-76,000): one core feature, authentication, Stripe billing and an 8 to 14 week timeline. No-code (Bubble, WeWeb) cuts the bill to 8,000-20,000 EUR but shifts the cost onto technical debt the moment you scale. The real question is not "how much" but "what is the shortest path to 10 paying customers?".
What an MVP actually costs by approach
An MVP is not a finished product: it is the minimal version that proves a customer will pay for one feature. A senior agency developer's day rate in 2026 sits between 500 and 700 EUR. A realistic MVP needs 45 to 100 person-days depending on billing and role complexity.
| Approach | Cost 2026 (EUR) | Timeline | Technical debt | Best for |
|---|---|---|---|---|
| No-code (Bubble/WeWeb) | 8,000 - 20,000 | 4-8 wks | High | Validate an idea fast |
| Senior freelancer | 20,000 - 45,000 | 8-14 wks | Medium | Technical founder present |
| Custom agency | 25,000 - 70,000 | 8-14 wks | Low | Raise funds, scale |
| Internal team (2 devs) | 90,000 - 160,000/yr | 12-20 wks | Low | After product-market fit |
No-code is excellent to test a hypothesis in a few weeks. It becomes a trap past a few hundred active users: platform limits, rising execution costs and the impossibility of hiring classic developers often force a full rewrite.
What the budget really covers
A serious quote breaks the budget down by functional block. Here is a 2026 order of magnitude for a custom B2B SaaS MVP.
| Block | Person-days | Indicative cost (EUR) |
|---|---|---|
| Product scoping + UX/UI design | 8-12 | 5,000 - 8,000 |
| Authentication + role management | 6-10 | 3,500 - 6,000 |
| Core feature (the value engine) | 20-35 | 12,000 - 22,000 |
| Stripe billing + subscriptions | 6-10 | 3,500 - 6,500 |
| Admin dashboard + basic analytics | 5-8 | 3,000 - 5,000 |
| Deployment + CI/CD + observability | 4-6 | 2,500 - 4,000 |
On top comes the infrastructure run: between 200 and 800 EUR/month in 2026 (cloud hosting, managed database, monitoring, transactional emails). Over a first year, budget the build plus 2,400 to 9,600 EUR of run.

Mini case study
Thomas, founder of an HR SaaS startup in New York, wants to launch an onboarding tool for accounting firms. He hesitates between no-code at 15,000 EUR and custom at 48,000 EUR. He targets 25 customers at 79 EUR/month in year one, or 23,700 EUR of ARR. No-code gets him signing 3 months earlier, but at 300 users he must rewrite everything (estimated 55,000 EUR). Going custom from the start, he pays 48,000 EUR once and avoids the rewrite: over 3 years the total gap favors custom as soon as the product finds traction. His decision: no-code to validate 5 customers, then switch to custom at the first traction signal.
FAQ
Can you build a SaaS MVP for under 25,000 EUR? Yes, in no-code or with a freelancer on a tightly scoped feature, between 8,000 and 20,000 EUR. Below that you get a prototype, not a billable product able to charge subscriptions.
How long until first revenue? With an 8 to 14 week build and a 1 to 3 month B2B sales cycle, expect 4 to 6 months before the first recurring paid subscriptions.
Should you integrate Stripe or another billing system? Stripe Billing remains the 2026 standard for B2B subscriptions: trials, proration, compliant invoices. Budget 3,500 to 6,500 EUR of integration and 1.4 to 2.9 % commission per transaction.
What should wait for V2? Anything not essential to proving value: enterprise SSO, advanced roles, public API, multi-language. Each deferral saves 3,000 to 10,000 EUR on the MVP.
Is an internal team better? Not before product-market fit. Two internal devs cost 90,000 to 160,000 EUR/year loaded; an agency lets you test without committing that payroll.
