You have a validated idea and a budget conversation coming. Every agency quote you have received is a different number with a different set of assumptions buried underneath it, and none of them explain why.
A production-grade MVP typically costs $35,000 to $250,000+, with most landing between $35,000 and $90,000 and complex builds running well beyond that. The number is driven less by feature count than by three things: how many external systems you integrate, whether you need real authentication and permissions on day one, and how much existing data has to migrate in. A single-user tool with no integrations sits at the bottom of that range. Anything touching payments, a CRM, or regulated data sits in the middle or above.
The cost most estimates omit is the second quarter. An MVP that reaches real users generates change requests, and a build with no budget left for the three months after launch tends to get abandoned at exactly the point it starts producing signal. Plan roughly 20 to 30 percent of the build cost for the first quarter post-launch. If a quote is silent on what happens after go-live, that is the question to ask before comparing prices.
| Profile | Typical cost | Typical timeline |
|---|---|---|
| Single-user tool, no integrations | $35,000–$50,000 | 8–10 weeks |
| Multi-user with auth and permissions | $50,000–$90,000 | 10–16 weeks |
| Payments, CRM or third-party integrations | $90,000–$150,000 | 14–20 weeks |
| Regulated data or complex migration | $150,000–$250,000 | 20+ weeks |
Budget a further 20–30% of build cost for the first quarter after launch. A build with nothing left for post-launch change tends to be abandoned exactly when it starts producing signal.
What moves an MVP budget most
- Integrations, not features, drive cost. Ten screens against one database is cheaper than three screens against Salesforce, Stripe and a legacy ERP. Each integration carries its own auth, error handling, rate limits and failure modes.
- Non-functional requirements get quoted as free. Authentication, permissions, audit logging, environments and deployment are frequently absent from a low quote — and they are not optional in production.
- Scope moves after work starts. The most expensive rebuild we see is not a bad architecture; it is an MVP scoped as a demo that then has to become a product.
How to scope an MVP without overspending
-
01
Write down the smallest thing a real user would pay for. Not the vision — the first transaction. Most MVP scope doubles because this was never written down.
-
02
List every external system the MVP must talk to on day one. Move anything that could wait to phase two; each one you defer removes real cost, not theoretical cost.
-
03
Decide explicitly whether this codebase is disposable. A throwaway prototype and a foundation you will build on for three years are different products at different prices. Both are valid; pretending a prototype is a foundation is not.
-
04
Ask any vendor to quote authentication, permissions, environments and deployment as separate line items. If they are missing, the quote is not comparable to one that includes them.
-
05
Run our build-cost calculator with your own numbers before you take another call. It uses the same constants we use internally.
The scope decisions are easy to write down and hard to hold. Six weeks in, a stakeholder asks for one more thing that is obviously small, and it is — but it is the fourth obviously small thing, and it touches the data model. What actually protects an MVP budget is not a scoping document, it is someone with the standing to say no to a founder. That is usually the thing a first-time team does not have, and it is why our Build engagements are milestone-gated rather than time-and-materials.
More on MVP cost
Sometimes — a genuinely single-purpose tool with no integrations and no compliance surface can land below that. We will tell you if yours qualifies. What we will not do is quote below $35,000 by omitting authentication, environments and deployment, then invoice for them later as change requests.
Most land between 10 and 16 weeks from kickoff to production. The variable is rarely engineering speed; it is how quickly decisions get made on your side. Builds with one empowered decision-maker consistently finish faster than builds with a committee.
That is a common starting point. We run a fixed-scope technical audit first ($7,500-$20,000) rather than quoting a rebuild blind — sometimes the existing codebase is fine and the problem is process. You get the audit findings either way, including if the recommendation is to keep your current team.
