Fixed price app development

One published price, one fixed deadline, and the overrun risk sits with us rather than you. How fixed pricing works and where its limits are.

The App14 team1 min read

The price is published, the deadline is fixed, and if the work takes longer than we thought, that is our problem.

The row that matters is the first one. Under time and materials, the person with the least control over how long the work takes carries all the risk of it taking longer. That is you.

The trade you are making

How we hold the line without billing you for changes

Three mechanisms, all agreed on day one.

Scope in writing. What is in, and just as importantly, what is out.

A version-two list. Anything you think of later goes here at no cost. It is not a bin; it is the input to whatever you build next, informed by real users.

A trade, not a bill. If something must go in mid-sprint, we tell you what comes out to make room. You decide. Nobody sends an invoice you did not expect.

Common questions

What happens if the work takes longer than expected?

That is our problem, not yours. The price does not change. This is the entire point of a fixed price and it is why we insist on fixing the scope first.

Can the price go up mid-project?

Not for the agreed scope. If you ask for something outside it, we either put it on a version-two list at no cost or quote it separately, agreed with you before any work happens.

Is fixed price worse for me than time and materials?

It is worse if your requirements are genuinely unknown, because you will pay for our uncertainty margin. It is better in every other case, because the risk sits with the party who can actually control it.

The App14 team · Design and engineering, Appetite Studio

App14 is the 14-day app sprint run by Appetite Studio, a London-registered design and engineering studio. We design, build, and ship production iOS and Android apps in two weeks, at a published fixed price. Everything we write here comes out of work we have actually delivered: the prices are our real prices, the timelines are our real timelines, and the limits are the ones we genuinely hold to.

Our articles are drafted with AI assistance and reviewed by the App14 team before publication. The prices, timelines, delivery record, and client outcomes described are our own.
