The verdict in three sentences
A well-scoped vertical SaaS MVP is built in 2026 for 30,000 to 90,000 EUR and ships in 8 to 14 weeks. The line item that blows up budgets is never the tech, it's unmanaged scope: every "just in case" feature adds 3,000 to 9,000 EUR. The founder's right question isn't "what does my full idea cost" but "what is the one thing a customer would pay for tomorrow."
What an MVP actually contains (and what it doesn't yet)
An MVP is not a watered-down v1: it's the smallest product that proves you can sell. In practice it ships authentication, subscription billing, and one core feature that solves an acute pain for a niche. Everything else waits for traction.
| Building block | In the MVP | Deferred to v1 | MVP order of magnitude |
|---|---|---|---|
| Auth + user management | Yes (email + simple SSO) | Fine-grained RBAC, multi-org | 3,000-7,000 EUR |
| Subscription billing (Stripe) | Yes (1-2 plans) | Usage-based, dunning | 4,000-8,000 EUR |
| Core business feature | Yes (one only) | Secondary modules | 9,000-28,000 EUR |
| Dashboard / reporting | Minimal (3-4 views) | Advanced analytics, exports | 3,000-9,000 EUR |
| Product onboarding | Manual/guided | Automated self-serve | 1,500-4,500 EUR |
| Third-party integrations | 0-1 | Integration marketplace | 2,000-7,000 EUR |
| Design system | Light (shadcn/Tailwind) | Proprietary design | 2,000-6,000 EUR |
The cost trade-offs that decide your burn rate
With limited starting capital, three trade-offs separate a 32,000 EUR MVP from a "MVP" at 75,000 EUR that no longer is one.
| Trade-off | Lean 2026 option | Expensive option | Cost gap |
|---|---|---|---|
| Platform | Responsive web only | Web + native iOS/Android | +20,000-45,000 EUR |
| Billing | Hosted Stripe Checkout | Custom billing portal | +6,000-16,000 EUR |
| Core feature | 1 workflow, 1 persona | 3 workflows, 3 personas | +16,000-38,000 EUR |
| Data | Simple multi-tenant | Per-tenant isolation, compliance | +9,000-22,000 EUR |
| Design | Open-source components | 100% custom UI | +4,000-13,000 EUR |
A healthy MVP aims for 6 to 9 months of runway after launch: better to ship at 32,000 EUR and keep cash for acquisition than spend 75,000 EUR before the first euro of revenue.

Mini case study
Thomas, founder of a scheduling SaaS for veterinary clinics in Nantes, hesitates between a "complete" scope (quoted at 82,000 EUR) and a tight MVP. We scope the MVP around a single feature — online booking synced to the schedule — plus auth and a 39 EUR/month subscription. Cost: 36,000 EUR, delivered in 11 weeks. With 40 paying clinics in 5 months (≈ 1,560 EUR MRR × 5), he validates demand and raises on real traction rather than a slide. The deferred scope (vet invoicing, SMS reminders) becomes a roadmap funded by revenue.
FAQ
Can you build a real SaaS MVP under 30,000 EUR? Yes if the core feature is simple and billing is standard (Stripe Checkout). Below 22,000 EUR you're usually talking prototype or no-code, useful to test the pitch but rarely billable long-term.
How long before the first paying customer? With an MVP delivered in 8-14 weeks, first payments often land 2 to 6 weeks after go-live if acquisition runs in parallel with development.
Custom code or no-code assembly? No-code validates a hypothesis fast (a few thousand euros), but a subscription SaaS benefits from going custom once traction appears — for performance, scalability and code ownership.
What budget after the MVP? Plan 30 to 50% of the initial cost per quarter to iterate toward v1, plus cloud hosting (200-800 EUR/month depending on load) and tooling.
Is MVP code throwaway? Not if written cleanly (TypeScript, tests on the core, CI/CD). A well-built MVP becomes the v1 foundation; it's excess technical debt, not the MVP itself, that forces a rewrite.
