How much does it cost to build a custom app for a small business in the UK?
Quotes for the same app can differ many times over. Here is what actually drives the number, so you can spot a sensible quote from a silly one.
Prices are a starting point in GBP and depend on scope. You get one fixed price in writing after a free 20-minute call.
A focused app that does one job well for a small UK business usually starts in the low five figures in pounds, built end to end; our app builds start from £10,000 and are priced by scope. Going below that generally means a template or a no-code tool, which can be the right call. Going far above it usually means an agency team and a longer spec than you need. The biggest cost lever is scope, not the hourly rate.
Why quotes vary so wildly
There is no such thing as "an app" for pricing purposes. A booking app for one Pilates studio and a marketplace with payments, messaging and two types of user are both "an app", and one is ten times the other. When you get a quote, you are really being told how much scope the builder heard, how many people they plan to put on it, and how much risk they are pricing in.
What moves the price
An app where one kind of person logs in and does three things is cheap. One where customers, staff and admins all see different things is not.
The moment users sign in, store data or pay, you need a proper backend: authentication, a database, secure storage, and rules about who can see what. This is where a lot of the real engineering lives, and where cheap builds fall over later.
iOS only, iOS and Android, or a web app that runs anywhere. A web app is often the fastest way to prove the idea; a native iOS app is right when it needs the camera, offline use, notifications and the App Store.
Every outside system it must talk to (Stripe, a calendar, accounting software, a maps service) adds work and, more importantly, adds things that can break.
An agency prices in project managers, account managers and juniors. A freelancer prices in only themselves, which is cheaper but riskier if they vanish. We sit in the middle on purpose: the people who do the strategy also do the build.
Realistic ranges
For a small business, an internal tool, such as the custom patient CRM we built for nutritionist Ericka Barbosa, or a simple customer-facing web app typically runs from the low five figures. A native iOS app with accounts, a real backend and App Store release, like Maintivo, is a bigger job and priced accordingly. Anything with two-sided users, payments and messaging is a product, not a tool, and should be budgeted like one. We would rather tell you the honest number on a call than print a price that does not fit your project, and we never charge for discovery.
How to keep the cost sane
Build the smallest version that a real customer would pay for, ship it, then add. Nearly every app that ran over budget did so because version one tried to be version three. A good builder will push back on scope; be suspicious of one who says yes to everything.
Check whether you need an app at all. Sometimes a well-built website with a booking system, or an off-the-shelf tool wired up properly, does the job for a tenth of the money. We cover that decision in custom software or off-the-shelf.
What is included when we build one
Positioning and a plain-English spec, design, the app itself, the backend, App Store submission if it is native, and the marketing site so people can actually find it. Everything is yours under the contract, including the code and the accounts, once the invoices are cleared. Keeping an app running afterwards (updates, security, small tweaks) is £850 a month, and new features are quoted separately. Third-party costs such as an Apple Developer account, API keys and hosting are yours. If you want to see how the process works step by step, read how to get a custom app built.
Related questions
Is no-code cheaper?
Usually yes to start, and it is a good way to test an idea. It gets expensive and limiting once you have real users, so plan for the point where you outgrow it.
How long does it take?
A focused first version is typically weeks, not months. Big scope and slow decisions are what turn it into months.
Do I own the code?
With us, yes. The intellectual property is yours under the contract, and the code and accounts are handed over once every invoice is cleared. Ask any builder this question before you sign.
