The verdict in three sentences
In 2026, a B2B SaaS MVP built by an agency costs EUR 25,000 to 70,000 (about USD 27,000 to 76,000) excluding tax and ships in 10 to 16 weeks, provided you limit it to 3 to 5 features that deliver the promise in your letters of intent. With EUR 80,000 of funding (honor loans, public grants, friends and family), keep at least 30 % of the budget for iterations after the first customers. Demand code ownership and a repository under your own account from day one.
Agency, freelancers or co-founder CTO
| Criterion | Agency (Paris or nearshore) | Coordinated freelancers | Co-founder CTO |
|---|---|---|---|
| MVP cost | EUR 25,000 to 70,000 | EUR 18,000 to 45,000 | EUR 0 to 15,000 + 10 to 30 % equity |
| Indicative day rate | EUR 550 to 800 (Paris), EUR 350 to 500 (nearshore) | EUR 450 to 700 | Deferred salary |
| Delivery time | 10 to 16 weeks | 12 to 24 weeks | 16 to 32 weeks |
| Project management | Included (project manager) | Your job | Shared |
| Main risk | Vendor dependency | Coordination, turnover | Co-founder conflict |
| Continuity after the MVP | Maintenance contract | Variable | Strong |
| Best if | Tight deadline, secured budget | Founder with product experience | Deep-tech heavy project |
For a non-technical founder in a hurry to turn letters of intent into paying contracts, an agency is usually the safest option, provided reversibility is properly framed.
Typical EUR 45,000 MVP budget
| Item | Days | Amount | Share of budget |
|---|---|---|---|
| Discovery, workshops and wireframes | 8 | EUR 5,200 | 12 % |
| UX/UI design (15 to 20 screens) | 10 | EUR 6,500 | 14 % |
| Development of the 4 core features | 32 | EUR 20,800 | 46 % |
| Authentication, roles, Stripe billing | 8 | EUR 5,200 | 12 % |
| Testing, acceptance and go-live | 7 | EUR 4,550 | 10 % |
| Project management | 4 | EUR 2,750 | 6 % |
| Total | 69 | EUR 45,000 | 100 % |
Based on an average day rate of about EUR 650. Add hosting (EUR 50 to 300 a month at launch), tools (email, monitoring, EUR 50 to 150 a month) and an iteration budget of EUR 10,000 to 20,000 over the next 6 months.
Framing scope to hit the deadline
Start from the sentence that keeps coming back in your letters of intent: that is the core feature. Add only what a customer needs in order to pay: account creation, roles (admin, user), a dashboard, an export and billing. Postpone multiple integrations, the native mobile app and multilingual support. Each secondary feature costs EUR 3,000 to 8,000 and one to two weeks.

On the contract side, require four clauses: assignment of economic rights on the code, a Git repository in your name, minimal technical documentation and admin access to hosting. These clauses make a handover to another team possible in about 5 to 10 days of transfer.
Mini case study
Julie, non-technical founder of a B2B startup in Paris, has signed 10 letters of intent with logistics SMEs and has EUR 80,000 (EUR 30,000 honor loan, EUR 30,000 French Tech grant, EUR 20,000 from friends and family). She hires an agency for a 4-feature MVP at EUR 45,000, delivered in 14 weeks. She keeps EUR 20,000 for iterations and EUR 15,000 for 12 months of hosting, tools and overheads. If 6 of the 10 prospects sign at EUR 400 a month, she reaches EUR 2,400 in monthly recurring revenue, or EUR 28,800 (USD 31,000) a year: enough traction to prepare a pre-seed round, with the MVP paid back by just over 18 months of revenue.
FAQ
Can a B2B SaaS MVP cost less than EUR 20,000? Yes, with a no-code or low-code tool and 1 to 2 features, for EUR 8,000 to 20,000. The limits show quickly beyond a few hundred users or with complex business rules.
Does public funding cover MVP development? In France, the French Tech grant (up to EUR 30,000, or EUR 90,000 in its Emergence version) and honor loans can cover part of the build. Allow 2 to 4 months of processing in your timeline.
Paris agency or nearshore? A nearshore agency (North Africa, West Africa, Eastern Europe) charges EUR 350 to 500 a day, a 30 to 40 % saving. Check for an English or French-speaking project manager, time zone overlap and SaaS references.
What does a SaaS cost after the MVP ships? Budget EUR 1,500 to 4,000 a month for maintenance, hosting and small changes. Infrastructure alone often stays under EUR 300 a month up to 1,000 users.
How do we avoid being locked in by the agency? Code in your own repository, written assignment of rights, documentation and admin access. A well-prepared handover takes 5 to 10 days.
