The verdict in three sentences
A credible B2B SaaS MVP in 2026 is built for 30,000 to 80,000 EUR in 10 to 16 weeks, provided you limit scope to a single core feature plus essentials (auth, billing, dashboard). No-code (Bubble, Xano) starts faster but becomes a trap past product-market fit: the rewrite costs more than the original custom build. The real variable isn't build price, it's time-to-market: every month of delay burns budget with no revenue.
What an MVP must contain (and nothing more)
The founder's number-one trap: confusing an MVP with a finished product. An MVP validates a market hypothesis with minimal engineering. Here's the typical budget breakdown of a 55,000 EUR MVP.
| Work package | Scope | Effort (days) | Cost (2026 ballpark) |
|---|---|---|---|
| Auth & accounts | Signup, email SSO, roles, multi-tenant | 8 | 4,800 EUR |
| Core feature | The unique value proposition | 30 | 18,000 EUR |
| Dashboard & reporting | Metrics view, CSV exports | 12 | 7,200 EUR |
| Billing & subscription | Stripe, plans, free trial | 10 | 6,000 EUR |
| Onboarding & emails | Activation flow, transactionals | 6 | 3,600 EUR |
| UI design & integration | Light design system, responsive | 14 | 8,400 EUR |
| DevOps & go-live | CI/CD, hosting, monitoring | 8 | 4,800 EUR |
| PM & QA | Scoping, testing, acceptance | 4 | 2,400 EUR |
| Total | ~11-14 weeks | 92 | ~55,200 EUR |
Anything not in this table (advanced roles, public API, custom analytics, mobile app) waits for market validation.
No-code vs custom code: the real 18-month cost
No-code wins on initial speed. But the math shifts once the product takes off and you add users, integrations and performance demands.
| Criterion | No-code (Bubble/Xano) | Custom code |
|---|---|---|
| MVP build cost | 12,000-25,000 EUR | 30,000-80,000 EUR |
| First version lead time | 5-8 weeks | 10-16 weeks |
| Platform subscription/yr | 2,400-9,000 EUR | 0 (infra ~1,500-6,000 EUR/yr) |
| Post-PMF rewrite cost | 40,000-90,000 EUR | 0 (you iterate) |
| Scalability ceiling | Medium (platform limits) | High |
| Code ownership | Partial | Full |
| Cumulative 18-month cost | ~70,000-140,000 EUR | ~45,000-95,000 EUR |
Verdict: no-code is excellent for a throwaway prototype or internal tool. For a SaaS you intend to scale, custom is cheaper over an 18-month horizon.
Agency vs in-house team: the day-rate math
| Option | Day rate / monthly cost | Ramp-up | Risk |
|---|---|---|---|
| Agency / studio | 450-650 EUR/day | 1-2 weeks | Low (seasoned team) |
| Assembled freelancers | 350-550 EUR/day | 2-4 weeks | Medium (coordination) |
| Full-time senior dev | ~7,000-9,000 EUR/month loaded | 2-3 months (hiring) | High (before PMF) |
Before product-market fit, a full-time hire locks up cash and freezes the stack too early. An agency ships fast, then you internalize once the market is validated.

Julien, founder of an HR startup in Nantes, wants to validate a skills-assessment SaaS. Raised: 200,000 EUR. He weighs a full-time hire at 8,000 EUR/month loaded (3 months hiring + 4 months dev = ~56,000 EUR and zero revenue before month 7) against an agency at 55,000 EUR delivering in 13 weeks. Choosing the agency, he launches his paid beta 4 months earlier. With 15 pilot clients at 300 EUR/month, that 4-month head start captures 18,000 EUR of recurring revenue plus traction proof for his next round. The cost of delay would have exceeded the theoretical savings of hiring.
FAQ
How long for a B2B SaaS MVP in 2026?
Expect 10 to 16 weeks with a dedicated team. Under 8 weeks, you cut billing or QA, which you pay for later. A well-scoped perimeter is the best accelerator.
Should I integrate Stripe from the MVP?
Yes, if your model is subscription. Charging from day one validates willingness to pay, the real product-market fit signal. Stripe integration is around 6,000 EUR on an MVP.
Is no-code really cheaper?
Over the first 6 months, yes. Over 18 months with growth, no: platform fees and above all the post-PMF rewrite (40,000-90,000 EUR) flip the math. Choose by your horizon.
What happens after the MVP?
A scale phase: infra hardening, advanced roles, API, analytics. Budget an evolution envelope of 40 to 60% of the initial build over the following 12 months, module by module based on traction.
Can I start with a 30,000 EUR budget?
Yes, with tight scope: one core feature, simple auth, basic Stripe billing. We cut the advanced dashboard and integrations. It's the right reflex to test a hypothesis before investing more.
