The verdict in three sentences
A useful custom SaaS MVP (one core feature, real authentication, Stripe billing) budgets in 2026 at 25,000-55,000 EUR for a launch in 10 to 14 weeks. The cost that explodes is never the core feature but the periphery: auth, billing, GDPR, admin dashboard, infrastructure. With available grants (early-stage subsidies, a 20% innovation tax credit), the net cost to reach the first paying customer can stay under 40,000 EUR.
What an MVP really costs in 2026
Price depends on feature count, domain complexity and expected polish. An MVP is not a finished product: it is the smallest scope that proves someone pays. Below 25,000 EUR you get a throwaway prototype; above 60,000 EUR you are no longer building an MVP but a v1.
| Deliverable | Scope | 2026 budget (EUR) | Timeline |
|---|---|---|---|
| Clickable prototype (Figma) | Flow + mockups, no code | 3,000 - 7,000 | 2-3 wks |
| Single-feature MVP | 1 core feature + auth + billing | 25,000 - 40,000 | 10-12 wks |
| Enriched MVP | 2-3 features + admin dashboard | 40,000 - 55,000 | 12-14 wks |
| Commercial v1 | multi-role, integrations, mobile | 60,000 - 110,000 | 16-24 wks |
The 2026 product day rate (developer + design combined) sits at 450-650 EUR in a Western European agency, versus 300-450 EUR nearshore. A 30,000 EUR MVP therefore equals roughly 50-65 person-days.
Where the budget goes: cost breakdown
The surprise for founders is that the feature justifying the product often accounts for under 30% of the budget. The rest funds what makes the product sellable and operable.
| Item | Share | Indicative cost (30,000 EUR) | Possible trade-off |
|---|---|---|---|
| Authentication + accounts | 12% | 3,600 EUR | Clerk/Supabase Auth to save |
| Stripe billing (subscriptions) | 10% | 3,000 EUR | Hosted Stripe Billing vs custom |
| Core feature | 28% | 8,400 EUR | Non-compressible |
| Dashboard + admin back-office | 18% | 5,400 EUR | Retool interface in phase 1 |
| UI design + flows | 14% | 4,200 EUR | Lightweight design system |
| Infra + deploy + GDPR | 10% | 3,000 EUR | EU hosting, vendor DPAs |
| Testing + fixes + launch | 8% | 2,400 EUR | Non-compressible |
To stay under 40,000 EUR, freeze multi-role, use a ready auth brick (Supabase, Clerk), replace the custom back-office with an internal tool like Retool, and limit third-party integrations to one (usually Stripe).
The grants that lower net cost
An early-stage founder can stack several 2026 schemes to cut the residual cost. These are orders of magnitude: exact amounts depend on the file and eligibility.
| Scheme | Nature | Indicative 2026 amount |
|---|---|---|
| Early-stage innovation grant | Subsidy/advance | up to 30,000 EUR |
| Innovation tax credit | 20% tax credit | 20% of eligible spend |
| Digital transition support | Coaching/aid | variable |
| Honour loan (0%) | 0% loan | 5,000 - 50,000 EUR |

On a 35,000 EUR MVP eligible for the innovation tax credit, the tax saving reaches about 7,000 EUR; combined with a grant, the net cost of reaching the first paying customer drops below 40,000 EUR, even 30,000 EUR depending on the file.
Build in-house vs agency vs studio
| Criterion | In-house hire | Product agency | No-code studio |
|---|---|---|---|
| Year-1 cost | 90,000-130,000 EUR (2 loaded salaries) | 25,000-55,000 EUR | 8,000-20,000 EUR |
| Time to MVP | 4-6 months (incl. hiring) | 10-14 wks | 4-8 wks |
| Code ownership | yes | yes | no (platform) |
| Marginal cost at scale | controlled | controlled | rises sharply |
| Risk | high (team to manage) | medium | low short-term, high long-term |
The no-code "free" gets expensive at scale: subscriptions rise with volume, and a rebuild becomes necessary around 30,000-50,000 records. To validate an idea fast it is unbeatable; for a product you want to sell for 3 years, a product agency is often the best risk/cost ratio.
Mini case study
Elodie, founder of a services SME, wants a SaaS MVP for tracking construction sites for tradespeople. Scope: one core feature (scheduling + timestamped photos), auth, Stripe billing at 29 EUR/month. Agency quote: 34,000 EUR, delivered in 12 weeks. She secures a 20,000 EUR grant and the tax credit returns ~6,800 EUR. Net cost: ~7,200 EUR of cash. With 25 paying customers at 29 EUR/month from month 4, she reaches 725 EUR MRR and repays the residual in under 12 months.
FAQ
What is the minimum budget for a real SaaS MVP in 2026? At least 25,000 EUR for a product with auth, one core feature and Stripe billing. Below that you fund a throwaway prototype, not a sellable product.
How long until the first paying customer? Between 10 and 14 weeks of development for a single-feature MVP, then 1-2 months of selling. Stripe billing from launch avoids rebuilding at your first customer.
Does the innovation tax credit apply to my MVP? The 2026 credit refunds 20% of eligible design spend for a new product, capped. On a 35,000 EUR MVP the saving nears 7,000 EUR depending on eligibility; confirm with your accountant.
Should I start in no-code to save? Yes to test an idea in 4-8 weeks for under 20,000 EUR. No if you target a product sold for 3 years: subscription costs and the rebuild wipe out the initial saving.
What must I freeze to stay under 40,000 EUR? Multi-role, multiple integrations and the custom back-office. A ready auth brick, one connector (Stripe) and an admin tool like Retool are enough for phase 1.
