The verdict in three sentences
A useful B2B SaaS MVP in 2026 costs between 35,000 and 90,000 EUR and ships in 3 to 4 months if you limit it to one core feature, authentication and billing. Beyond that you are no longer funding an MVP but a disguised V1, which doubles the budget before you even have a paying customer. The golden rule: spend the minimum to prove someone will pay, then reinvest where traction appears.
What an MVP really covers (and what it excludes)
The most common trap is confusing an MVP with a finished product. An MVP proves a value hypothesis with the narrowest possible scope. Here is the difference in scope and cost between a true MVP and a full V1.
| Scope | MVP (3-4 months) | Full V1 (7-9 months) |
|---|---|---|
| Business features | 1 core + 2 secondary | 5 to 8 modules |
| Auth / roles | Basic (2 roles) | SSO, granular roles |
| Billing | Simple Stripe Checkout | Subscriptions, dunning, multi-country VAT |
| Dashboard | 3-4 metrics | Configurable reporting |
| Integrations | 0 to 1 | 3 to 6 (API, webhooks) |
| Indicative budget | 35,000-90,000 EUR | 90,000-200,000 EUR |
If a V1-column line feels essential from day one, challenge it: in 8 cases out of 10 it can wait for the first customer feedback.
Agency, freelancer or product studio: which for which budget
The vendor choice weighs as much as the scope. 2026 day rates in Western Europe sit in these ranges.
| Option | 2026 day rate (EUR) | Typical MVP cost | Main strength | Risk |
|---|---|---|---|---|
| Solo freelancer | 350-600 | 30,000-55,000 | Cost, agility | Bus factor, no design |
| Freelance collective | 400-650 | 40,000-70,000 | Flexibility, seniority | Coordination on you |
| Product agency | 450-750 | 50,000-90,000 | Full team, framing | Price, heavier process |
| Startup studio (equity) | variable | 20,000 + equity | Long-term alignment | Equity dilution |
For a first SaaS without a CTO, a product agency or a senior collective cuts the risk of an MVP that never finds its market for lack of framing.

Mini case study
Thomas, founder of an HR SaaS scale-up in Berlin, wants to validate an annual-review tracking tool. He picks a 48,000 EUR MVP over 3.5 months instead of a 110,000 EUR V1. With 12 pilot customers at 190 EUR/month, he reaches 2,280 EUR MRR by month 5, a projected payback of 21 months. More importantly, pilot feedback stops him building two modules he thought essential: a 30,000 EUR saving in wasted development.
FAQ
Is a 35,000 EUR MVP really sellable? Yes, if it solves a precise problem for a clear segment. Many B2B SaaS signed their first 10 customers with a deliberately narrow product; perceived value comes from solving the problem, not from the feature count.
How long until the first paying customer? Count the build (3-4 months) plus 1 to 2 months of beta. In practice, aiming for a first payment between month 4 and month 6 is realistic if customer discovery was done upfront.
Should I code it myself to save money? Rarely worth it without technical skill. No-code can validate a hypothesis cheaply, but a B2B SaaS selling to companies quickly needs security, integrations and reliability that no-code tools cap.
What monthly run budget should I plan? Between 200 and 800 EUR/month in the MVP phase (hosting, database, monitoring, transactional emails). This grows with users but stays marginal against development cost.
What happens after the MVP? You reinvest where traction is confirmed: requested integrations, scaling, higher-value modules. The V1 budget ideally unlocks with the first recurring revenue as a safety net.
