The verdict in three sentences
A credible B2B SaaS MVP costs 40,000 to 90,000 EUR ex. VAT in 2026 over 10 to 16 weeks, the goal being to test the market before a raise, not to build everything. No-code ships in 4 to 6 weeks for 8,000 to 20,000 EUR but caps quickly on multi-tenancy, billing and performance. A custom stack (Next.js + Supabase) costs more but holds up, raises better and avoids a costly rewrite at traction.
How much a B2B SaaS MVP costs
Budget depends on the core-product scope and the robustness expected.
| MVP level | Included | Price ex. VAT | Timeline |
|---|---|---|---|
| No-code MVP | 1 feature, basic auth, simple payment | 8,000-20,000 EUR | 4-6 wks |
| Lean custom MVP | Auth, 1-2 core features, Stripe | 40,000-55,000 EUR | 10-12 wks |
| Investor MVP | + multi-tenant, onboarding, dashboard | 60,000-78,000 EUR | 12-14 wks |
| Scale-ready MVP | + roles, API, analytics, tests | 80,000-90,000 EUR | 14-16 wks |
| Infrastructure/month | Hosting, database, emails, monitoring | 150-600 EUR/month | ongoing |
Stripe subscription billing alone (trials, plans, taxes, invoices) is 8,000 to 15,000 EUR of well-done development.
No-code or custom stack
The choice depends on your horizon: validate an idea fast, or build a fundable asset.
| Criterion | No-code | Custom (Next.js + Supabase) |
|---|---|---|
| Time-to-market | 4-6 weeks | 10-16 weeks |
| Initial cost | 8,000-20,000 EUR | 40,000-90,000 EUR |
| Robust multi-tenancy | Hard | Native |
| Cost at scale | Explodes (usage-based) | Under control |
| Advanced Stripe billing | Limited | Full |
| Investor appeal | Low | High (owned code) |
| Rewrite risk | High | Low |
Simple rule: no-code to validate a market signal cheaply, custom as soon as you target a raise or enterprise clients.

Mini case study
Julien, founder in Paris, wants to validate a B2B compliance SaaS before a seed round. He hesitates between no-code (15,000 EUR) and custom (68,000 EUR). He targets 20 pilot clients at 290 EUR/month, i.e. 5,800 EUR MRR by month 4.
With custom at 68,000 EUR, delivered in 13 weeks, he gets a demonstrable multi-tenant product for due diligence, infrastructure at 380 EUR/month. At 20 clients he reaches 69,600 EUR ARR, which, with owned code and clean architecture, supports a seed valuation well above the initial premium. No-code would have required an estimated 50,000 EUR rewrite before Series A, erasing the upfront saving.
FAQ
What is the minimum budget for a credible B2B SaaS MVP? In custom, count at least 40,000 EUR ex. VAT in 2026 for a product with auth, one to two core features and Stripe billing. Below that, you are in no-code or prototype territory.
How long until launch? A 3-4 month time-to-market is realistic for a custom MVP (10-16 weeks). No-code drops to 4-6 weeks but at the price of technical limits.
What infrastructure cost at launch? Between 150 and 600 EUR/month depending on traffic and services (database, transactional emails, monitoring). It grows gradually with users, without explosion if the architecture is clean.
Do we need multi-tenancy from the MVP? If you target enterprises, yes: it avoids a rewrite at traction and reassures in due diligence. Multi-tenancy adds about 10,000 to 18,000 EUR to the build.
Is no-code a bad choice? No, to validate a market signal cheaply it is excellent. It becomes risky as soon as you target enterprise clients or a raise, because it caps on performance and billing.
