The verdict in three sentences
A B2B SaaS MVP costs between EUR 40,000 and 90,000 (about USD 43,000 to 97,000) in 2026, over 10 to 14 weeks. With EUR 50,000, you get a sellable product with 3 to 5 core features, authentication, Stripe subscriptions and a dashboard, but no mobile app and no multiple integrations. The classic trap is spending 80% of the round on the MVP and having nothing left for the 6 months of iteration that follow.
What EUR 50,000 really buys
With an average day rate of EUR 550 to 750 in 2026, EUR 50,000 represents 70 to 90 days of work across design, development, testing and release. Here is a realistic split for a cash flow forecasting SaaS.
| Block | Days | Cost (EUR 650 day rate) | Scope |
|---|---|---|---|
| Scoping, user flows and mockups | 10 | EUR 6,500 | 12 to 15 screens validated with 5 target users |
| Technical core (auth, multi-company, roles) | 12 | EUR 7,800 | Sign-up, team invites, permissions |
| Bank import (aggregator connector) | 12 | EUR 7,800 | Daily account sync |
| Forecasting engine and scenarios | 18 | EUR 11,700 | Core feature, 3 scenarios per company |
| Dashboard and exports | 10 | EUR 6,500 | 13-week charts, Excel and PDF export |
| Stripe subscriptions and billing | 6 | EUR 3,900 | 2 plans, 14-day free trial |
| Testing, security and release | 9 | EUR 5,850 | Automated tests, backups, monitoring |
| Total | 77 | EUR 50,050 | 12 weeks |
What this budget does not cover: native mobile app, integrations with 4 accounting tools, predictive AI trained on your data, offline mode, white label.
Three MVP levels compared
| Level | Budget | Timeline | Core features | For whom |
|---|---|---|---|---|
| Validation MVP | EUR 25,000 to 40,000 | 6 to 9 weeks | 1 to 2 | Test willingness to pay with 10 clients |
| Sellable MVP | EUR 40,000 to 60,000 | 10 to 14 weeks | 3 to 5 | First 50 paying clients |
| Robust MVP | EUR 60,000 to 90,000 | 14 to 20 weeks | 5 to 8 + 2 integrations | Demanding markets (finance, health) |
| Monthly hosting | EUR 100 to 300 | Cloud, database, transactional email | ||
| Monthly third-party tools | EUR 150 to 600 | Bank aggregator, monitoring, support |
For a finance tool, the "sellable" level is the minimum: a CFO will not buy cash flow software that does not connect to the banks.
Allocating a EUR 300,000 round
| Item | Amount | Share of round |
|---|---|---|
| MVP (initial build) | EUR 55,000 | 18% |
| Iterations over 6 months (2 to 3 days per week) | EUR 45,000 | 15% |
| Hosting and tools over 18 months | EUR 9,000 | 3% |
| Acquisition and sales (events, LinkedIn, content) | EUR 90,000 | 30% |
| Founder pay and first salesperson | EUR 80,000 | 27% |
| Legal, accounting and contingency reserve | EUR 21,000 | 7% |
The rule observed among B2B SaaS companies that reach their first 50 clients: keep at least as much for iterating as for building over the first 12 months, combining development and client feedback.
Mini case study
Sophie, a former CFO of a mid-sized company, launches a cash flow forecasting SaaS in Toronto for SMEs with 20 to 200 employees. She raises EUR 300,000 (about USD 325,000) and commissions a sellable MVP at EUR 54,000, delivered in 12 weeks.

Her pricing is EUR 149 per month per company. She needs 30 clients to cover hosting, tools and 2 days of iteration per week (about EUR 5,000 per month in total). Signing 6 clients per month after launch, she reaches that threshold in month five, with EUR 4,470 of monthly recurring revenue. At 12 months, 70 clients represent EUR 10,430 of MRR, or EUR 125,000 annualized, enough to prepare a second round with real metrics.
FAQ
Technical co-founder or an agency for the MVP?
An agency delivers faster (10 to 14 weeks) on a fixed budget. A technical co-founder costs less cash but 15 to 25% of equity, and often takes 4 to 6 months to ship alone.
No-code or custom code for a finance SaaS?
No-code suits a validation MVP under EUR 20,000. For a bank-connected tool with security requirements, custom code avoids a full rebuild at 50 clients.
Who owns the delivered code?
The contract must provide full assignment of IP rights and handover of the Git repository at delivery. Investors check this systematically during a Series A.
How do we avoid budget overruns?
Freeze 3 to 5 core features and a fixed price per 2 to 3 week phase. MVPs that drift by more than 30% almost always added features along the way.
How much does maintenance cost after launch?
Allow EUR 1,500 to 4,000 per month for fixes, updates and small improvements, on top of EUR 100 to 300 for hosting.
