Fixed price MVP
Fixed Price MVP Development: What the Price Covers, How Long It Takes and How to Choose a Partner
A fixed price only protects a founder when the scope behind it is written well enough to test. Here is what a fixed price MVP includes, what three weeks can and cannot buy, how the number gets set, and what to check before you sign.
Short answer
Fixed price MVP development means the agency agrees one number for a written scope before any code is written, and carries the risk if the work takes longer. It works when every screen has acceptance criteria. The price covers the agreed flows, backend, admin tools, store release and fixes to anything in scope that does not work. It does not cover new features, changes of direction or third party fees. Most fixed price MVPs take 8 to 12 weeks; three weeks buys a clickable prototype and a fixed scope, not a launched product.
What is a fixed price MVP?
A fixed price MVP is a first version of a product delivered for one number agreed in advance. The number stays the same if the build takes longer than planned, because the scope behind it was defined and tested on paper first.
Founders with limited runway like the model because the budget stops moving. That only holds when the scope is precise enough that both sides would agree whether a screen works. A one page list of feature names is not a scope; it is an invitation to argue later.
The rest of this guide covers what sits inside and outside the price, realistic timelines, how the number gets set and what to check in a quote. For how we run these projects end to end, see our page on fixed price app development, and for startups specifically, MVP development for startups.
What a fixed price MVP includes, and what it does not
The scope document is the dividing line. Everything written in it, including the backend and the admin side, is inside the price. Anything added later, and anything paid to a third party, is outside it.
Inside the price
- Every screen and flow in the written scope
- The backend, database and integrations listed in it
- An admin panel for the tasks you run every week
- Release to the App Store and Google Play
- Fixes to anything in scope that does not work as agreed
Outside the price
- Features that are not in the scope document
- Changes of direction after the design is approved
- Third party fees: store accounts, hosting, messaging, payments
- Content, copy and data you supply
- Marketing and growth after launch
When something new comes up mid build, it is written down, priced and agreed before anyone works on it. Our guide to change requests in a fixed price project shows how that conversation runs without stalling the build.
Can a fixed price MVP be built in three weeks?
Rarely, if you mean a product real users rely on. Three weeks is enough for a clickable prototype and a fixed scope. An MVP with a backend, an admin panel and a store release usually takes 8 to 12 weeks, and longer with payments, two user types or offline work.
Clickable prototype and fixed scope
Designed screens you can tap through, plus a written scope that a fixed price can be set against.
MVP users can rely on
Working apps, backend, admin tools and release to both stores for one core job.
MVP with heavier parts
Payments between users, two user types talking to each other, or work that must happen offline.
Speed comes from a fixed scope, not from rushing. On Souly, a community app for Zurich, a specification of 36 screens was agreed before development; design then took about two weeks and development about two months in two parallel streams.
The MVP app examples article shows how five of our first releases were scoped, and our guide on how long it takes to build an MVP explains what moves the timeline.
How the fixed price for an MVP gets set
The number comes last. First the scope is written and checked screen by screen, then it is estimated, and only then fixed. Payment follows milestones, and delivery ends with a signed acceptance protocol.
Discovery and scope
A short discovery workshop turns the idea into screens, flows and acceptance criteria. It costs less than one change of direction in the middle of a build.
Estimate and one fixed number
Each screen and integration is estimated against the written scope. The result is one price and one timeline, with the assumptions written next to them. Our article on how app development estimates are made shows the method.
Contract and milestones
Payments are split into stages tied to delivered work, and the fixed price contract transfers the economic rights to the code to you with the final payment.
Build with a working app every two weeks
You test progress on your own phone throughout the project, so problems surface while they are still cheap to fix.
Acceptance and warranty
Delivery is closed with a signed acceptance protocol checked against the scope. On larger contracts we add a one year warranty on the software. See how acceptance works in a fixed price project.
Worked example: from a wish list to a fixed price MVP scope
Take a booking app for independent personal trainers. The founder arrives with eight wishes. Each one is sorted into version one, later, or a decision only the founder can make, because it depends on the business model rather than on the code.
In version one
- Client books a sessionThe core action the product exists for
- Trainer sets available hoursBooking is impossible without it
- Reminder notificationsMissed sessions cost trainers money
- Minimal admin panelApprove trainers and view bookings
Founder decides
- Card payment at bookingIn if paid sessions are the product
- Chat with the trainerIn if the ongoing relationship is the value
Later
- Reviews and ratingsNeed booking volume to mean anything
- Loyalty programmeRetention tools come after clients exist
The middle column is where scopes go wrong. On EveSport, a trainer booking platform, chat and payments belonged in the first release because the product was an ongoing paid relationship. For a different business the same two items would wait. Our guide to MVP app features walks through this sorting in more detail.
How to fit a fixed price MVP into a tight budget
The budget goes further through scope decisions, not cheaper developers. Remove whole features, run some work by hand at first, and use one codebase for both platforms.
- Cut features, not quality. A smaller scope that works completely beats a larger one with gaps, and anything in scope that fails is the agency's to fix inside the price.
- Do some work by hand at first. Approvals, refunds or matching can run from the admin panel for months. Loopy Jobs launched its first version without automated payments, as described in our guide to marketplace app payments.
- Use one codebase for iOS and Android. Flutter or React Native means one team, one set of changes and one test pass instead of two.
- Use a managed backend where it fits. Services such as Supabase handle login, database and file storage without a server built from scratch.
- Fix the scope before asking for a quote. Comparing quotes against different scopes compares guesses. For founders watching runway closely, our guide on MVP development for bootstrapped startups goes further, and what drives MVP app cost covers the budget side.
How to choose a fixed price MVP development partner
Look past the number at four things: how detailed the scope is, who owns the accounts, who pays for fixes after launch, and how often you see working software. A cheap quote that fails on these usually costs more by the end.
The scope is one page of feature names
Without screens and acceptance criteria, every disagreement becomes a negotiation.
Ask insteadWhat appears on each screen, and what counts as done?
Store accounts and hosting sit with the agency
If the accounts are not yours, leaving the agency means rebuilding access to your own product.
Ask insteadAre the store and hosting accounts in my company's name from the first week?
Bugs after launch are billed by the hour
Then the fixed price only covered writing the code, not making it work.
Ask insteadIs everything in scope guaranteed to work, with fixes at no extra cost?
Nothing to test until the end
Problems found in the final week are the most expensive ones to fix.
Ask insteadWill I have a working build on my phone every two weeks?
Two more questions settle most decisions: who owns the code once you have paid, and how the code is handed over if you later build a team of your own. Our guides on comparing app development quotes and MVP codebase handover cover both.
When a fixed price is the wrong choice
If the requirements for the first version are still unclear, a fixed price will either carry padding for risk or break the first time something changes. Start with discovery or a small paid prototype, then fix the price.
Products built around unproven core technology are a poor fit too. A fixed price rewards clarity; it cannot create it. If you are unsure which model suits you, compare fixed price vs time and materials.

FAQ
Can an MVP be built on a fixed price?
Yes, when the scope is written screen by screen with acceptance criteria before the price is set. Without that level of detail, a fixed price either includes padding for risk or turns into a dispute about what was promised.
How long does a fixed price MVP take?
Most take 8 to 12 weeks. Products with payments between users, two user types or offline work take 12 to 22 weeks. A clickable prototype and a fixed scope can be ready in 2 to 3 weeks.
What happens if we change something during the build?
Small adjustments inside agreed screens are normal. New features or changes of direction are written down, priced and agreed before work on them starts, so the original price and timeline stay readable.
What is not included in a fixed price MVP?
Features outside the scope document, third party fees such as store accounts, hosting and payment processing, and content or data the client provides. Marketing after launch is also separate.
Who owns the code of a fixed price MVP?
You do. The economic rights to the code transfer to the client with the final payment, and store and hosting accounts should sit in your company's name from the first week.
How do bootstrapped founders fit an MVP into a limited budget?
By cutting whole features, running some tasks by hand in an admin panel, using one codebase for both platforms and fixing the scope before asking for quotes. Cheaper developers rarely save money once fixes are counted.
Where can I see prices for a fixed price MVP?
On our pricing page. Each project receives one fixed number after the scope is agreed.
