Mobile app development cost for a small service business

Why most app cost guides don’t fit your business

Search for mobile app development cost and most of what you find comes from app agencies. One guide puts a basic app at $25,000 and an enterprise app at over $400,000. Another says $40,000 to $150,000, sometimes more than $300,000. Those numbers aren’t wrong for what they price. They just price something else.

Those guides mostly price apps launched to the public. One uses Airbnb, Tinder and Uber as its examples. Apps like those need sign-ups from strangers, two app store versions, heavy traffic, marketing and a team to run them. The guides we read also list hourly rates by country, which tells you who they’re written for.

A small service business usually needs something narrower. Your users are people you know: your crew, your office and your own customers. The app does a few jobs well, like showing today’s jobs or taking a booking. That’s a smaller build, and it should be priced like one.

Neither guide we cite links to the data behind its price ranges, when we checked in October 2026. So treat any range, ours included, as a starting point for a written quote, not a price.

First decide: a store app, a web app, or no new app

This choice moves the price more than any single feature. There are three ways to put your business on a phone, and each costs differently to build and to keep running.

For example, a property manager who wants tenants to send repair requests with photos rarely needs a store app. Tenants won’t download an app to report a leak once a year, but they will tap a link in a text.

Apple’s rules also cut both ways. Apple says a store app should offer more than “a repackaged website.” Wrapping your website in an app just to get it on the store can be turned down. For an app only your own staff use, Apple offers private “custom apps.” They’re shared through your business’s Apple Business account (formerly Apple Business Manager), with redemption codes or device management, instead of the public App Store. Those still go through Apple’s review.

Here are the three options side by side:

• A web app. It runs in the phone’s browser from a link, on iPhone and Android alike. People can add it to their home screen, where it gets an icon and can open without the browser bar. There’s one version to build, no store review, and an update reaches everyone at once.
• A store app. It’s downloaded from Apple’s App Store or Google Play. It fits best when the app leans on the phone itself: hours without signal, all-day barcode scanning, or tracking a route in the background. A web app can handle some of this, so ask your builder which your list needs. A store app means developer accounts, reviews, listings and more phones to test.
• No new app at all. Many off-the-shelf field service apps come with a phone app for crews. If one fits how you work, paying to rebuild it buys you nothing new. Our guide to custom software or an app off the shelf helps you decide.

What drives mobile app development cost

Once you know which kind you need, these are the things that move the number. Each one is simply more to build and test. None of them means the idea is a bad one.

When you picture “the app,” you probably picture the phone screens. The office side is often just as much work, and it’s the part owners most often leave out of their list:

• The office side. Every crew or customer app needs screens where the office creates jobs, assigns them and sees what came back from the field.
• Kinds of users. A tech, a dispatcher, an owner and a customer each see different screens and have different rules about what they can see and change.
• Working without signal. Showing today’s jobs needs a connection. Letting a tech finish a job in a basement and send it later means saving work on the phone, then sorting out clashes when two people changed the same job.
• Photos, signatures and files. Each needs storage, a way to upload on a weak signal, and a place where it shows up on the job.
• Payments. Sending a payment link is simpler than taking a card on site, deposits, partial payments and refunds.
• Connections to other apps. QuickBooks Online, Stripe, Square or Google Calendar each need their own setup and testing.
• Both app stores, and how they’re built. Two store versions mean two listings, two reviews and testing on more phones. Many builders write one app from a shared code base that runs on both, which costs less than two separate apps. Ask which one your quote assumes. A web app skips most of this.
• Moving old data in. Customers spread across a notebook, three phones and an old app take real time to clean up before day one.
• Logins and access. Who can see which customers and jobs has to be checked on every screen, not just hidden from the menu.
• Who builds it. A quote from one independent developer and one from a firm can differ a lot, partly because they include different things: testing, project management and fixes after launch. A no-code tool costs less to start but has its own limits. Ask each who fixes problems when someone is away, and whether another developer could pick up the code.

What this looks like in four kinds of business

Here is how those drivers play out in a few trades. These are made-up examples to show the thinking, not quotes.

Notice that the store app shows up only once. For most service businesses, the phone is a window into the office’s system, and the system is where most of the cost sits.

• A 6-truck HVAC company. Techs need today’s jobs, the equipment at each address, photos, a signature and a card payment on site. Some basements have no signal. That points to a store app that works offline, plus office screens, connected to QuickBooks Online. It’s the biggest build of the four.
• A property manager with 40 units. Tenants send repair requests with photos, and each vendor sees only the jobs assigned to them. A web app opened from a text link does the job, with no store app to keep up.
• A café taking catering orders. Customers order a few times a year, so few will download an app. An order form on the website, deposits through Square or Stripe, and a kitchen list for staff do more for less.
• A furniture showroom with a delivery crew. Drivers need the day’s stops, addresses and a signature at the door. A web app on their phones usually covers it. If they scan every item onto the truck, a store app starts to earn its cost.

What you keep paying after launch

An app isn’t paid off at launch. Phones get new software every year, connected apps change how they work, and someone has to keep it all running. One agency guide we read suggests budgeting 15–⁠25% of the build price a year for upkeep; another says about 20%. A monthly figure in writing beats any rule of thumb, so ask for one.

A good support plan spells out fixes, updates, reply times and what costs extra. Our guide to who handles software maintenance and support covers what to get in writing.

Here is what to budget for, with fees as listed when we checked in October 2026:

• Apple’s App Store. The Apple Developer Program costs $99 a year.
• Google Play. A one-time $25 registration fee.
• Card payments. Stripe, for example, lists 2.9% + 30¢ per successful online payment on US cards, with no monthly fee. It lists different rates for cards taken in person or typed in by hand.
• No App Store cut on your work. Apple’s rules say payments for goods or services used outside the app, like a repair or a catering order, must not go through in-app purchase. So your card processor’s fee applies, not Apple’s in-app purchase cut.
• Hosting and care. The server your app talks to, backups, updates when Apple or Google release new phone software, and fixes. A fair quote lists this as a monthly line.
• The apps you keep. QuickBooks Online or Square stay on their own bills.

Ways to spend less without a worse app

Most savings come from building less at first, not from cheaper hours. A smaller first version also teaches you what your crew actually uses before you pay for the rest.

If you want to know what happens between the quote and launch day, how a mobile app gets built, step by step walks through it.

• Start with a web app. One version covers iPhone and Android, and you can move to a store app later if your crew truly needs one.
• Build one job from start to finish first. For example, “a tech sees today’s jobs and marks each one done,” before quotes, payments and reports. Our guide to scoping your first software release shows how to pick it.
• Keep the apps that already work. Connect to QuickBooks Online or Square instead of rebuilding them inside your app.
• Clean your customer list before the build. One tidy spreadsheet is cheaper to bring in than three phones’ worth of duplicates.
• Ask for a fixed price for a written list. An hourly estimate can grow. A fixed price puts the risk of a slow week on the builder.
• Build for the team you have. Plan for your next few hires, not a second location you might open one day.

Questions to ask before you accept an app quote

Have each builder price the same written list, then ask these. Good answers are specific, and they belong in the agreement. Our guide to choosing a custom software company covers the wider questions about the team itself.

• Store app or web app, and why that one for my crew or customers?
• Can a web app handle each phone feature on my list, like the camera, signatures or maps, on both iPhone and Android? Get that answer in writing.
• Does the price cover iPhone and Android, and which phones do you test on?
• Are the office screens included, or only the phone app?
• What happens when a tech loses signal halfway through a job?
• Whose name are the Apple and Google developer accounts in? They should be in your business’s name.
• Who owns the code, and from what date?
• What will I pay every month after launch, and what does it cover?
• When Apple or Google release new iPhone or Android software, who updates the app, and is that in the monthly price?
• Is this a fixed price, and how are changes priced?

What an app costs with us

We build custom business software for service businesses, and a crew or customer app is usually one part of it. These are our prices as of October 4, 2026.

What we build works in the browser on phones, tablets and computers, so many owners don’t need a store app at all. If your team needs an app on their home screen, we can build that too. In the examples above, the property manager would usually fit the one-system range. A build like the HVAC company’s, with office screens, payments and a crew app, is the full-system range. The café may need only a focused fix if one order form is enough.

Every launch includes 30 days of fixes. Hosting and care are a monthly line, priced in your quote, and card fees go to your card processor. You own the code we write once the project is paid in full. Hosting runs on our account, and you can take it over after payment. We connect to QuickBooks Online, Square, Stripe, Shopify, Google Calendar, Gmail or Outlook, and check anything else before we quote.

The first call is free, and you get a fixed price in writing within 48 hours of it. If an off-the-shelf app already does what you need, we’ll say so. See how we build custom business software, or read what custom software costs for more on what moves the number.

• A focused fix, $750–$3,000 over 1–⁠2 weeks. For example, one new form or report, or a connection between two apps you already use.
• One business system, $6,000–$18,000 over 6–⁠10 weeks. For example, scheduling and invoicing for a crew of 5 to 10, connected to QuickBooks Online, that crews open on their phones.
• A full system, $18,000–$40,000 over 10–⁠16 weeks. Customers, jobs, quotes, invoices, payments and a crew phone app, together.
