The verdict in three sentences
A non-technical founder who raised 400,000 EUR (about 460,000 USD) pre-seed has to ship a sellable MVP in 4 months without burning more than a quarter of the round. A B2B SaaS MVP costs 40,000 to 110,000 EUR (about 46,000 to 127,000 USD) in 2026, with day rates of 550 to 750 EUR in Paris, often 150 to 220 USD an hour in New York, against 350 to 450 EUR a day with a French-speaking nearshore team. The rule: build multi-tenancy and Stripe billing into v1, and postpone anything that does not get the first paying customer to sign.
The real scope of a sellable B2B SaaS MVP
A B2B MVP is not a demo. It must let a customer company create its workspace, invite colleagues, use the core feature daily and pay without manual intervention. Everything else waits for v2. Here is a typical breakdown, as 2026 ballpark figures for a nearshore team (average day rate 400 EUR).
| Functional block | v1 status | Person-days | Estimated cost (excl. VAT) |
|---|---|---|---|
| Authentication, Google and Microsoft SSO | Must have | 8 to 12 | 3,200 to 4,800 EUR |
| Multi-tenancy (organisations, roles, invitations) | Must have | 15 to 25 | 6,000 to 10,000 EUR |
| Core feature (the problem you solve) | Must have | 40 to 110 | 16,000 to 44,000 EUR |
| Stripe billing (plans, trial, invoices, tax) | Must have | 10 to 18 | 4,000 to 7,200 EUR |
| Dashboard and CSV exports | Must have | 8 to 15 | 3,200 to 6,000 EUR |
| Guided onboarding and transactional emails | Must have | 6 to 10 | 2,400 to 4,000 EUR |
| Third-party integrations (Salesforce, HubSpot, Slack) | Postpone | 15 to 30 | 6,000 to 12,000 EUR |
| Native mobile app | Postpone | 40 to 80 | 16,000 to 32,000 EUR |
| Advanced AI module, public API | Postpone | 20 to 40 | 8,000 to 16,000 EUR |
The must-have blocks add up to 87 to 190 person-days, plus 15 to 20 % for scoping, design and QA. Hence the 40,000 to 110,000 EUR range depending on how complex the core feature is.
New York, Paris or nearshore: comparing real costs
The day rate is only part of the equation. Cultural fit, time zone and the team's ability to challenge the product matter just as much. French-speaking nearshore teams (Dakar, Tunis, Casablanca, Abidjan) sit within one hour of Paris and overlap 3 to 5 hours with New York mornings.
| Criterion | Agency or freelancers in Paris | French-speaking nearshore |
|---|---|---|
| Senior developer day rate | 550 to 750 EUR | 350 to 450 EUR |
| 150 person-day MVP | 82,500 to 112,500 EUR | 52,500 to 67,500 EUR |
| Time difference with Paris | 0 h | 0 to 1 h |
| Working language | French | French and English |
| In-person workshops | Easy | 1 to 2 trips to plan (1,500 to 3,000 EUR) |
| Share of a 400,000 EUR round consumed | 21 to 28 % | 13 to 17 % |
| Runway months saved (burn of 25,000 EUR a month) | baseline | + 1.2 to 1.8 months |
For reference, a New York agency billing 150 to 220 USD an hour puts the same 150 person-days at roughly 180,000 to 264,000 USD. The 30,000 to 45,000 EUR saved against Paris funds more than a month of runway or a first salesperson for three months. The risk to manage is project leadership: require a product owner on the vendor side and a demo every two weeks.
The costs that follow launch
A SaaS is never finished. Budget recurring costs into the round from day one: hosting and cloud services at 150 to 600 EUR a month at the start (managed PostgreSQL, storage, email, monitoring), Stripe fees of 1.5 % plus 0.25 EUR per transaction in Europe (2.9 % plus 0.30 USD in the US), and ongoing development of 3,000 to 8,000 EUR a month if you keep the team to iterate. Observability and security tooling (Sentry, backups, occasional penetration tests at 4,000 to 8,000 EUR) is part of a B2B product that holds up in front of a procurement team.
Mini case study
Julien, a non-technical founder of an HR startup, raised 400,000 EUR. He must show 10 paying customers at 300 EUR a month before his seed round. Paris quote: 165 person-days at 650 EUR, or 107,250 EUR. Nearshore quote: 165 person-days at 400 EUR, or 66,000 EUR, plus 2,400 EUR of travel, 68,400 EUR in total.

The 38,850 EUR gap lets him hire a business developer at 4,500 EUR fully loaded for 8 months. If that hire closes 6 more customers than Julien alone, that is 1,800 EUR of extra MRR, or 21,600 EUR of ARR, a metric that weighs heavily in a seed valuation (often 8 to 15 times ARR at this stage). Choosing the vendor becomes a traction decision.
FAQ
How much does a B2B SaaS MVP cost in 2026?
Between 40,000 and 110,000 EUR excl. VAT for a sellable MVP with multi-tenancy and billing. Below 30,000 EUR, it is usually a no-code prototype that will need rewriting.
How long does a B2B SaaS MVP take?
Allow 3 to 4 months: 3 weeks of scoping and design, 9 to 12 weeks of development in two-week sprints, then 2 weeks of acceptance testing with 3 to 5 pilot customers.
Do you really need multi-tenancy in v1?
Yes, adding it later costs 2 to 3 times more because it touches every table and every query. At 6,000 to 10,000 EUR upfront, it is the cheapest insurance in the project.
Who owns the source code?
Require full assignment of rights in the contract and a Git repository in your name from day one. Investors check this during due diligence.
No-code or code for a B2B MVP?
No-code works to validate interest with 5 to 10 users. To bill companies with security and SSO requirements, code becomes necessary from the first 20 customers.
