"How much does a SaaS MVP cost?" has no single answer, because the same question hides two very different products.
One person means a prototype to prove people want the idea. Another means a first version real customers pay a subscription for. The engineering between those is substantial, and that's the whole reason cost estimates on the internet range from $5,000 to $150,000.
Let's separate them.
Two things called an MVP
A prototype proves the idea works and that people want it. It handles the core flow with real data, looks credible in a demo, and deliberately skips the hardening. From $7,500, in 3–6 weeks.
A production MVP carries paying customers. Same core idea, plus the engineering a demo never shows: proper authentication and permissions, subscription billing that can't double-charge, tests on the flows that make money, monitoring, backups. From $25,000, in 2–4 months.
Both are legitimate. Building the second when you needed the first wastes money, and building the first when you needed the second loses customers.
What a SaaS MVP specifically needs
SaaS adds requirements a simple app doesn't have, and they're the parts founders most often forget to budget for:
| Component | What it involves | Typical cost |
|---|---|---|
| Accounts and teams | Sign-up, roles, invitations. Multi-user from the start, because retrofitting teams is expensive | $2,500 – $6,000 |
| Subscription billing | Plans, trials, upgrades, downgrades, failed payments, cancellations | $3,000 – $8,000 |
| Multi-tenancy | Each customer's data properly separated, enforced by the database | $3,000 – $8,000 |
| The core product | Whatever actually makes it worth paying for | $8,000 – $30,000+ |
| Admin and support tools | So you can help a customer without opening the database | $2,000 – $5,000 |
| Onboarding | Getting a new signup to value quickly, which is what decides retention | $2,000 – $5,000 |
| Emails | Welcome, trials ending, payment failed, password reset | $1,500 – $4,000 |
| Analytics | Which features get used, where people drop off | $1,500 – $4,000 |
Some of these overlap, which is why a production SaaS MVP lands around $25,000–$60,000 rather than the sum of the rows.
The four that cost more than founders expect
Subscription billing. Charging a card once is easy. Handling a trial ending, a card expiring, an upgrade mid-cycle, a refund, and a failed renewal is where the work is. Get it wrong and you either lose revenue quietly or charge people twice, and both damage trust.
Multi-tenancy. Keeping each customer's data separate has to be enforced at the database level, not just in the interface. This is the most common serious flaw we find in AI-built SaaS products, and it's the one that ends companies.
Onboarding. Founders treat it as polish. It decides whether trials convert, and it's usually the highest-return work in the whole build.
Admin tooling. Without it, every support request means someone querying the production database by hand. That's slow, risky, and doesn't scale past your first dozen customers.
What to leave out of a first version
Almost everything else. Specifically:
- Every pricing tier you imagined. Launch with one or two.
- Single sign-on and enterprise features. Build these when an enterprise customer asks and is willing to pay.
- A public API. Until customers ask, it's a maintenance commitment with no revenue.
- Native mobile apps. A responsive web app covers most B2B SaaS.
- AI features, unless AI is the product. See the AI app development cost guide if it is.
- A custom design system. Use a component library and spend the design budget on onboarding.
The discipline isn't "build less". It's "build the part people pay for, properly".
What it costs to run
SaaS has ongoing costs from day one:
- Hosting and database, modest at launch, growing with customers
- Payment processing, a percentage of revenue
- Transactional email, usually small
- Error monitoring and analytics, often free at low volume
- Maintenance, 15–25% of build cost per year (guide)
Budget for maintenance from the start. A SaaS product that stops being updated stops being bought.
Timeline
| Phase | Duration |
|---|---|
| Discovery and design | 2–4 weeks |
| Prototype build | 3–6 weeks |
| Production MVP build | 2–4 months |
| Beta with real customers | 3–6 weeks |
The beta matters more in SaaS than anywhere else. Your first ten paying customers will tell you which half of your roadmap to delete.
Cheaper ways to find out
If the budget is tight, spend it on learning rather than building:
- Sell before you build. Take deposits or signed letters of intent against a prototype.
- Do it manually first. Deliver the service by hand for the first customers, and automate only what proves valuable.
- Use off-the-shelf where you can. Authentication, billing, and email all have mature providers. Building your own is rarely a good use of a first budget.
- Launch to one segment. A narrow product for a specific audience beats a broad one nobody identifies with.
What a reasonable quote looks like
For a production SaaS MVP, expect an itemised estimate by phase and role, an explicit list of what's excluded, working software every two weeks, and a post-launch support period. A single lump sum with no breakdown tells you nothing, and a quote produced without any scoping conversation is a guess.
Our guide to comparing quotes covers how to normalise several against each other.
Getting a number for yours
Our rates are on the pricing page, and the custom software cost guide has a calculator you can model your own product with.
