The verdict in three sentences
A B2B SaaS MVP in 2026 costs EUR 20,000-60,000 for a single core feature, shipped in 8-16 weeks. Infrastructure (auth, billing, multi-tenant) represents 30-40 % of the budget and must never be sacrificed, because it's what makes the product sellable. Break-even sits between 30 and 60 paying customers: aiming for that number, not functional perfection, is the only healthy seed strategy.
Minimum viable scope: include vs exclude
The first mistake of a SaaS founder is wanting to build everything. A successful MVP does one thing remarkably well. Here is the dividing line.
| Include in the MVP | Exclude (v2 or later) |
|---|---|
| 1 core feature that solves THE problem | Secondary "nice to have" modules |
| Authentication + account management | Enterprise SSO, SAML |
| Subscription billing (Stripe) | Complex multi-currency billing |
| Multi-tenant (customer data isolation) | White-label and advanced theming |
| Basic dashboard | Advanced analytics and BI exports |
| Minimal guided onboarding | Integrations marketplace |
Every deferred feature is two to four weeks of development and EUR 5,000-12,000 saved to validate the market faster.
The cost of SaaS infrastructure in 2026
Invisible infrastructure separates a prototype from a product. Here are 2026 ranges for the essential technical building blocks.
| Technical block | 2026 dev cost (EUR) | Recurring cost |
|---|---|---|
| Authentication & account management | 4,000 - 9,000 | included / low |
| Billing & subscriptions (Stripe) | 5,000 - 12,000 | 1.4 % + Stripe fees |
| Multi-tenant architecture | 6,000 - 15,000 | infra scaling |
| Infra & hosting (setup) | 3,000 - 8,000 | EUR 200-800/month |
| Transactional emails & notifications | 2,000 - 5,000 | EUR 20-100/month |
| Monitoring & logs | 1,500 - 4,000 | EUR 30-150/month |
Hosting an MVP runs between EUR 200 and 800/month at launch, a cost that scales with customer count, therefore easily absorbed once the first subscriptions come in.
No-code vs custom: the cost of time-to-market
No-code can validate an idea in weeks but shows its limits once traction hits. Honest 2026 comparison.

| Criterion | No-code (Bubble, etc.) | Custom-built |
|---|---|---|
| Initial cost | EUR 5,000-20,000 | EUR 20,000-60,000 |
| Launch timeline | 3-8 weeks | 8-16 weeks |
| Monthly platform cost | EUR 30-500 | hosting only |
| Scalability beyond 100 customers | limited | native |
| Code ownership | no | yes |
| Recommended for | validating a hypothesis | a product meant to last |
The winning 2026 strategy: validate in no-code if the idea is uncertain, move to custom once traction passes 20-30 paying customers.
Mini case study
Thomas, co-founder of an HR startup in Bristol, wants to launch a SaaS for annual performance reviews. MVP scope: campaign creation, evaluation forms, manager dashboard. Accepted budget: core feature EUR 22,000, auth + billing + multi-tenant EUR 16,000, design + onboarding EUR 8,000, i.e. EUR 46,000 delivered in 13 weeks. Infra at EUR 350/month. With a subscription at EUR 39/user/month and an average basket of 8 users, each customer brings EUR 3,744/year: break-even is reached at 15 paying customers, i.e. a return on investment in under 18 months with modest growth.
FAQ
How long to ship a SaaS MVP? Between 8 and 16 weeks for well-scoped custom work. Below 8 weeks you usually cut infrastructure corners (billing, multi-tenant), which costs more to fix later.
Can you launch a SaaS for under EUR 20,000? Yes, in no-code or with an ultra-reduced scope. But a SaaS built to scale with robust billing and multi-tenant rarely drops below EUR 20,000 in custom work without technical debt.
What's the real cost of payment infrastructure? Developing the Stripe integration costs EUR 5,000-12,000 once, then Stripe takes roughly 1.4 % + fixed fees per transaction in Europe. It's non-negotiable for a subscription SaaS.
At how many customers is a SaaS MVP profitable? Depending on subscription price, between 30 and 60 paying customers cover a EUR 40,000 MVP over 18-24 months. With a high ticket (>EUR 100/month), the threshold drops to 15-25 customers.
Should you start with no-code? If the idea isn't validated, yes: it avoids burning EUR 40,000 on a false hypothesis. If the market is already proven, custom avoids a costly migration later.
