The verdict in three sentences
A B2B SaaS MVP delivered in 12 weeks in Amsterdam costs between EUR 40,000 and 100,000 excluding VAT in 2026, depending on the number of core features and the level of integration required. You keep the budget under control by limiting scope to 3 to 5 features that prove value to your first 10 paying customers. Dutch support schemes such as the RVO Innovation Credit and the WBSO R&D tax credit can cover a meaningful share of the cost before your seed round.
What a 12-week B2B MVP contains
A B2B MVP is not a clickable prototype. It must take payments, handle several customer accounts and produce usable data for your pitch. An investor preparing a EUR 300,000 to 800,000 ticket wants to see active users, retention and recurring revenue, however small.
| Building block | Typical content | Share of budget | 2026 range (EUR excl. VAT) |
|---|---|---|---|
| Discovery and UX | Workshops, user flows, Figma mockups | 10 to 12% | 4,500 to 11,000 |
| Technical foundation | Authentication, multi-tenancy, roles | 15 to 20% | 6,500 to 19,000 |
| Core features (3 to 5) | The business logic that creates value | 40 to 45% | 16,000 to 45,000 |
| Billing | Stripe Billing, plans, free trials | 8 to 10% | 3,000 to 10,000 |
| Admin dashboard | Customer tracking, support, metrics | 7 to 10% | 3,000 to 8,500 |
| QA and go-live | Testing, monitoring, backups | 8 to 10% | 3,000 to 9,500 |
| Total | 100% | 40,000 to 100,000 |
The line that most often overruns is core features. Every feature beyond the fifth adds EUR 7,000 to 14,000 on average and one to two extra weeks.
How many days, at what rate
In Amsterdam, SaaS-focused freelancers and studios charge EUR 650 to 850 per day in 2026. For comparison, Bordeaux sits at EUR 550 to 750 and a French-speaking nearshore team at EUR 250 to 400. A 12-week MVP typically involves a tight team of two to three people.
| Role | Amsterdam day rate 2026 | Days over 12 weeks | Indicative cost (EUR excl. VAT) |
|---|---|---|---|
| Product owner | 700 to 850 | 15 to 25 | 10,500 to 21,250 |
| UX/UI designer | 650 to 750 | 10 to 18 | 6,500 to 13,500 |
| Senior full-stack developer | 700 to 850 | 30 to 50 | 21,000 to 42,500 |
| Mid-level full-stack developer | 600 to 700 | 0 to 20 | 0 to 14,000 |
| DevOps (ad hoc) | 750 to 850 | 2 to 5 | 1,500 to 4,250 |
On a fixed price, an agency usually adds a 10 to 15% risk margin. On time and materials, you pay the days actually worked but carry the overrun risk. For a first MVP, fixed price per phase (discovery, then two-week sprints) offers the best balance.
Funding and recurring costs
| Item | 2026 amount | Comment |
|---|---|---|
| WBSO R&D tax credit | 32 to 40% of eligible wage costs | Applies to development hours, apply in advance |
| RVO Innovation Credit | from EUR 50,000 (loan) | For larger technical risk projects |
| Regional innovation vouchers (MIT) | up to EUR 20,000 | Depends on province and call |
| Hosting (Vercel, AWS, Scaleway) | EUR 50 to 300/month | Depends on traffic and database |
| SaaS tooling (email, monitoring, analytics) | EUR 40 to 150/month | Postmark, Sentry, PostHog |
| Corrective maintenance | EUR 600 to 1,700/month | 1 to 2 days per month |
Work out your funding gap before the round: a EUR 65,000 MVP with EUR 20,000 from an innovation voucher and EUR 15,000 from WBSO leaves EUR 30,000 to fund from founders' equity or angels.

FAQ
Can a B2B MVP really ship in 12 weeks?
Yes, if the scope is frozen at 3 to 5 features at the end of discovery. Beyond that, expect 14 to 18 weeks and a budget that often exceeds EUR 100,000.
Do I own the code at the end?
You should, through an intellectual property assignment clause in the contract. Also require access to the Git repository from week one, at no extra cost.
When should I apply for WBSO?
Before the hours are worked, since WBSO only covers R&D hours planned in an approved application. Applications can be filed up to three times a year.
Which stack should I choose for a SaaS MVP?
Next.js, TypeScript and PostgreSQL cover 80% of B2B needs and make hiring easier later. Infrastructure stays under EUR 300 a month up to a few hundred customers.
What does it cost after the MVP?
Plan EUR 5,000 to 15,000 a month to iterate, which means one or two part-time developers. Seed money usually funds this budget first.
