How Much Does a SaaS MVP Cost?
A SaaS MVP typically costs €15,000–€60,000+ depending on scope, team structure, and definition of 'done'.
A SaaS MVP typically costs €15,000–€60,000+ to build, with the final number driven by feature scope, who builds it, and how strictly you define "done." The cheapest path is rarely the lowest total cost, because rework on a thin architecture usually outweighs the upfront savings.
What goes into the cost
A SaaS MVP price is not one line item. It bundles several distinct pieces of work:
- Auth and accounts — sign-up, login, password reset, roles.
- Multi-tenancy — keeping each customer's data isolated. This is the single biggest hidden cost driver.
- Core feature — the one workflow your product exists to do.
- Billing — subscription logic, usually via Stripe.
- Admin and ops — dashboards, basic analytics, email (transactional + notifications).
- Deployment and infra — hosting, CI, environments, backups.
Cutting any of these does not remove the work; it defers it. Multi-tenancy bolted on after launch commonly costs around 3× what it would have cost to build in from day one.
Cost by team structure
| Approach | Cost | Timeline |
|---|---|---|
| Offshore freelancer | €5k–€20k | 2–6 months |
| Solo full-stack developer | €15k–€40k | 6–12 weeks |
| Boutique agency | €30k–€80k | 4–6 months |
| In-house first hire | €80k–€150k/year | 6–12 months |
Why agency quotes are higher
Agencies price in a project manager, account management, dedicated QA, and margin. You are paying for a team that is also spread across other clients, so coordination overhead is built into the rate. The trade-off is process and redundancy if a person leaves.
Why the cheapest bids cost more later
The lowest bids win by cutting architecture. You get a working demo that does not survive its first ten paying customers: no tenant isolation, no migration path, brittle billing. The savings evaporate the first time you need to refactor the foundation under live users.
When to spend more vs. less
- Spend less when you are validating demand and can ship a narrow, single-workflow product to a handful of users. A focused MVP at the lower end of the range is enough to learn.
- Spend more when you already have signed pilots, handle payments or sensitive data, or know multi-tenancy and billing are core from day one. Underbuilding here is the expensive mistake.
Common mistakes
- Treating the MVP as the final product. It is a learning tool, not v1 of everything.
- Skipping multi-tenancy to save money. The most-deferred, most-expensive omission.
- Comparing quotes on price alone. A €15k quote and a €40k quote are usually scoping different products, not the same one at different rates.
- No fixed scope. Open-ended hourly work on a vague spec is how MVP budgets double.
A concrete example
A booking SaaS like BookBed (Flutter + Firebase + Stripe, with bidirectional iCal sync to Airbnb and Booking.com) needs real multi-tenant data isolation, subscription billing, and reliable third-party sync from the start — those put it toward the middle of the range. A simpler operational tool such as a clinic dashboard (Callidus, React + Firebase) or an ordering site (Pizzeria Bestek, React + Supabase) can ship nearer the lower end because the surface area is smaller. The deciding factor is integration depth and data isolation, not feature count.
Key takeaways
- Budget €15k–€60k+ for a real SaaS MVP; the spread reflects scope and architecture, not just hourly rates.
- A solo full-stack developer with fixed scope can deliver leaner than a traditional agency by removing coordination overhead.
- Build multi-tenancy and billing in from day one — deferring them is the costliest decision you can make.
- For a scoped number on your specific feature set, contact for a quote rather than relying on a generic range.
