App Development Company Cost: How Agencies Price Work

This guide explains all three so you can read a quote properly and compare bids fairly.

Our own price sheet is public (a simple single-platform app costs $5,000 to $12,000 with us, an iOS and Android app $8,000 to $18,000, and a website plus both apps $12,000 to $25,000), but this article is about reading any company's quote, not only ours. What it will do is show you the pricing models companies use, what a serious quote must contain, the drivers that move the number, and the questions that expose a weak proposal. If you want the wider picture on what an app itself costs, read how much it costs to develop an app first.

What you are paying an app development company for

You are paying for senior people's time, organised into a process that turns a rough idea into a working app on two stores, plus the accountability that comes with a company rather than an individual. The time is the largest part of the cost. The process and the accountability are why a company costs more than the sum of its hourly rates.

A typical build uses several roles, even on a small project: a product lead who scopes and runs the work, a designer, one or more mobile engineers, a backend engineer, and someone who tests. Each role touches your project for a different number of hours, and the mix changes with the kind of app. A content app leans on design. A marketplace leans on backend. A field tool leans on testing on real devices. When you read a quote, you are reading an estimate of those hours, priced at that company's rates, wrapped in that company's margin.

The rest of the cost is the wrapper: project management, meetings, documentation, code review, release handling and the warranty on defects. Companies that skip these look cheaper on paper and cost more by the second month.

The four ways app development companies charge

Companies charge in one of four ways: fixed scope, time and materials, a monthly retainer, or a dedicated team. Each moves the risk somewhere different, and the right one depends on how clear your scope is.

Most first builds do best on fixed scope, because a first version has a clear job and a budget you need to protect. Time and materials suits a second phase once real users are telling you what to build next. Our own model is fixed scope for the build and an optional retainer afterwards, which is described on the pricing page.

What a proper quote contains

A proper quote is a scope document with a price attached, not a price with a paragraph attached. If you cannot tell from the quote exactly what will exist at the end, you cannot compare it with anything. Use this checklist against every proposal you receive:

• A list of screens and user roles. Customer, admin, staff, and what each can do.
• Platforms. iOS, Android or both, and whether the build is native or cross-platform.
• Integrations named one by one. Payments, maps, messaging, your CRM, your booking system. Each one is real work.
• What is out of scope. This list is as important as the one above. A quote with no exclusions has hidden ones.
• Backend and hosting. Who builds the API, where it runs, and whose account it runs on.
• Design deliverables. Wireframes, visual design, a clickable prototype, or all three.
• Testing. Which devices and OS versions, and whether accessibility is checked.
• Store submission. Whether listings, privacy forms and review handling are included.
• Milestones and payment schedule. What you see at each milestone before you pay for it.
• Ownership. Source code, design files, store and cloud accounts in your name at handover.
• Warranty. How long defects are fixed at no charge after launch.
• Change process. How a scope change is priced and approved.

The shortest way to get a quote like this is to send a clear brief. Our guide to writing an app development brief shows what to include on one page.

What moves the number

Six drivers change an app development company's price far more than the category of app does. When two quotes differ a lot, one of these is almost always the reason.

Notice that the company's hourly rate is not on that list. Rates differ between companies, but scope differences swamp rate differences on almost every project. The guide to reducing app development cost works through each driver in more detail.

How to compare quotes from different companies

Compare scope first, price second. Put the quotes side by side and check whether each one includes the same screens, platforms, integrations, backend, testing and store work. In our experience the cheapest quote is usually missing something the others priced in, most often the backend, the store submission, or testing on real devices.

Then look at how each company handles risk. A fixed price with a clear scope and a change process moves risk onto the company. An open-ended estimate moves it onto you. A quote that is far below the others with no exclusions listed has moved the risk onto you without saying so.

Finally, compare the people. Ask who will actually build the app and whether you can speak to them before you sign. A company that fronts a salesperson and hides the engineers is a company you will be chasing for answers later. The article on questions to ask an app development company gives you a script for that call, and if you are weighing a company against a single contractor, read app development company vs freelancer.

Costs that sit outside the build

The build quote is not the total cost of owning an app, and a good company will tell you that unprompted. Budget separately for these, because none of them is optional once the app is live:

• Developer accounts and store fees. Apple and Google each charge for a developer account, and the stores take a share of in-app payments.
• Hosting and third-party services. Cloud hosting, push notification services, maps, email and SMS providers all bill monthly on usage.
• Maintenance. New iOS and Android versions arrive every year, store policies change more often, and libraries need updating. See what app maintenance involves.
• Analytics and monitoring. Crash reporting and product analytics tools, many with free tiers that end as you grow.
• Marketing and launch. Store listing assets, a landing page, and whatever it takes to get the first users.
• Your own time. Someone on your side has to make decisions, test builds and answer questions every week.

Warning signs in a proposal

A weak proposal usually shows itself before you sign. These are the signs we would walk away from if we were the buyer:

• A price with no scope document, or a scope that fits in two sentences.
• No list of exclusions.
• A promise of a specific outcome, such as a ranking, a download count or a revenue figure.
• Payment mostly up front rather than on milestones you can check.
• Source code, store accounts or hosting that stay in the company's name.
• No named engineers, or engineers you are not allowed to talk to.
• A timeline that is far shorter than everyone else's for the same scope.
• No mention of testing, warranty or what happens after launch.

If you are also deciding whether to build the team yourself instead of hiring a company, the trade-offs are set out in in-house vs agency app development.

Get a fixed-scope quote

The fastest way to find out what your app would cost is to ask for a quote that meets the checklist above. Send us a one-page description of who the app is for, the three things it must do, the systems it must connect to and any hard deadline. A senior engineer replies within 24 hours with questions, and you get a written scope and a fixed price before any work starts. Start on the contact page, or read how our pricing works first.
