What an MVP Really Costs in 2026: Fixed Price vs. Hourly

You have an idea. You've probably had it for a while. What you don't have yet is proof that it works, and that's exactly what an MVP is for: the smallest version of your product that lets real users, or investors, tell you whether you're onto something before you commit to building the whole thing.

The tricky part isn't building it. Plenty of agencies can write the code. The tricky part is paying for it without the bill spiraling before you even launch, and without discovering three months in that "small MVP" has quietly become a much bigger, much more expensive project than the one you originally agreed to.

The hourly trap

Most local development agencies quote an hourly rate, typically somewhere between €75 and €175 per hour, with a blended team rate (design, development, QA, project management combined) landing around €100 to €150 per hour. On paper, that sounds manageable. You do some quick math, estimate a few hundred hours, and arrive at a number that seems reasonable.

In practice, an MVP that looks small in a kickoff meeting regularly ends up costing €30,000 to €65,000 or more, especially once the scope shifts partway through, which it almost always does. A feature that seemed simple in the planning phase turns out to need three extra screens. A "nice to have" quietly becomes a "must have" once the design is in front of you. None of these individual changes feel unreasonable in the moment, but they add up fast when every hour has a price tag attached.

The reason this happens is structural, not personal. It's rarely bad faith on the agency's side. With an hourly rate, every meeting, every revision, every "can we also add" costs you money, and the agency has little built-in incentive to keep things tight, because their revenue is directly tied to the number of hours logged. You're not just paying for development. You're paying for every conversation about the development, every round of feedback, every Slack message that turns into a call.

Why founders underestimate this going in

Most founders don't get burned by dishonesty, they get burned by optimism. Everyone involved genuinely believes the estimate at the start. The problem is that an hourly contract has no natural brake on scope creep: every small addition is technically billable and technically reasonable on its own, and there's no single moment where anyone says "wait, this is now a different project." By the time the total is visible, you're too far in to easily walk away, and the agency has no strong incentive to have flagged it earlier.

What a fixed-price model changes

We build MVPs for a flat fee, ourselves included: we built Asignu, our own European e-signature platform, using exactly this process, from a blank page to a product that's now live with paying customers. We didn't design this model in theory. We used it on our own product first, which meant we felt every part of it that doesn't work in practice before we ever offered it to a client.

A fixed price forces the conversation to happen upfront instead of on every invoice. Before any code is written, you get a concrete proposal: scope, timeline, and one number. There's no ambiguity about what's included, and no incentive on our side to stretch the project out, because the price doesn't change if the work takes longer than expected. That risk sits with us, not with you.

Just as important: before development starts, you see interactive mockups of your MVP, free of charge, and click through them yourself. You approve the design before a single line of code gets written, not after you've already paid for a version you're not sure about. This single step removes most of the expensive surprises: by the time development starts, you've already seen roughly what you're getting, and the team building it isn't guessing at what you meant.

What the process actually looks like

A typical fixed-price MVP starts with an intake conversation about your idea, your target users, and the core functionality that actually matters for a first version, together with an honest conversation about what can reasonably wait for a later release. From there, you receive a proposal with a fixed scope, a fixed timeline, and a fixed price. Once that's agreed, the design phase starts with interactive mockups you review and approve before any development begins. Development itself follows, with weekly updates or demos so you're never waiting weeks to see progress, followed by testing and a live launch.

Payment is typically split across the project rather than paid entirely upfront or entirely at the end: a portion at kickoff, a portion once you approve the mockups, and the remainder at delivery, so both sides have skin in the game at every stage.

What to ask any MVP partner before you sign

If you're evaluating agencies, a handful of questions tend to separate the fixed-price partners from the hourly ones in disguise. What happens if the scope changes halfway through? If the answer involves a new invoice for every small change, you're back in hourly territory with extra steps. Do you see and approve the design before development starts, or only after the fact? And what's excluded from the price? Ongoing maintenance after launch is reasonably a separate line item, since that's an open-ended commitment rather than a fixed project, but development, design, and deployment should not be excluded or treated as add-ons.

The real question an MVP needs to answer

An MVP is meant to answer one question: does this work? Does it attract real users, does it solve the problem you think it solves, is there a business here worth building further. That question shouldn't require an open-ended budget to answer, and the price you pay to find out shouldn't be the biggest variable in the whole process.
