You need to decide what problem the app solves, who will use it, and how much you can spend before talking to a developer
Building an app for your business is not the same as building a website. An app lives on a phone or tablet, works offline sometimes, and costs more to build and maintain. Before you contact a developer, you need to know what you actually need the app to do, who will use it, and whether an app is the right tool at all. Many business owners discover halfway through that a website or a simpler tool would have solved the problem for a fraction of the cost.
The first step is to write down the specific job you want the app to do. Not "increase sales" or "improve customer experience" — those are business goals. Write the actual task: "Let customers order takeout from their phone and pick it up in 30 minutes" or "Let field technicians log service calls without returning to the office." The clearer you are about this one job, the cheaper and faster the app will be to build.
Key Takeaways
- Write down the specific task your app needs to do before you talk to any developer, because vague goals lead to expensive rewrites.
- Decide whether you need an app at all — a website, a text message system, or existing software might solve the problem for less money.
- Choose between native apps (built separately for iPhone and Android), cross-platform apps (one codebase for both), and web apps (run in a browser), based on your budget and how many people will use it.
- Budget for ongoing costs after launch: hosting, updates, bug fixes, and new features typically cost 20 to 40 percent of the original build price each year.
- Get a written contract that specifies what the app will do, how much it costs, when it launches, and who owns the code when it is finished.
Decide whether you actually need an app
Many business problems do not need an app. Before you commit to building one, ask whether an existing tool already does the job. If you need customers to book appointments, a calendar tool like Calendly or Acuity Scheduling might be enough. If you need to collect information from customers, a form tool like Typeform or Google Forms works on phones and costs almost nothing. If you need staff to access information while away from the office, a website that works on mobile browsers might be cheaper and easier to maintain than an app.
An app makes sense when you need features that a website cannot do well: offline access (the app works even without internet), push notifications (the app sends alerts to the phone), or integration with phone hardware like the camera or GPS. If your business does not need those things, start with a website or a simpler tool. You can always build an app later if the business grows and the need becomes clear.
Understand the three types of apps and their trade-offs
Native apps are built separately for iPhone (using a language called Swift) and for Android (using a language called Kotlin or Java). Each version is built from scratch, so native apps cost roughly twice as much as other options. The payoff is that they run fast, feel natural on each phone, and can use all the phone's features. If your app needs to be very fast or needs deep access to the phone's camera, location, or sensors, native is the right choice.
Cross-platform apps are written once in a framework like React Native or Flutter, then compiled to run on both iPhone and Android. They cost less than native apps because the developer writes the code once instead of twice. They are slower than native apps and sometimes feel less natural on the phone, but for most business tasks the difference does not matter. If you have a small budget and need the app on both phones, cross-platform is usually the practical choice.
Web apps run in a phone's browser, like a website. They are the cheapest to build and the easiest to update, because you change the code once and everyone sees the change when ready. The downside is that they cannot work offline, cannot send push notifications, and cannot access some phone features. Web apps work well for internal tools (staff using it at work) or for straightforward customer-facing tasks like checking an order status.
Understand what developers will ask you and why
When you meet with a developer or development company, they will ask questions that seem obvious to them but might feel strange to you. They are asking because the answers change the price and the timeline. Write down your answers before the meeting so you do not have to guess.
| What they ask | Why it matters |
|---|---|
| How many people will use this app? | A tool for 10 staff members costs less to build and host than one for 10,000 customers. The developer needs to know how much server power to plan for. |
| Do users need to create accounts and log in? | User accounts add weeks to the timeline and cost because the developer has to build find login, password recovery, and data storage. |
| Does the app need to connect to your existing software? | If the app needs to pull data from your accounting software, your customer database, or your inventory system, the developer has to build that connection. This is often the most expensive part. |
| What phones and versions do you need to support? | Supporting older phones and older versions of iOS or Android takes extra time. If you only need to support the current version of each phone, the app is cheaper and faster to build. |
| When do you need this launched? | A tight important date means the developer has to turn down other work or hire more people, which costs more money. Realistic timelines are cheaper. |
Get a written contract that specifies what you are paying for
Before work starts, you and the developer need a written agreement. This is not about not trusting the developer — it is about both of you being clear on what "done" means. The contract should say what the app will do (the specific features), how much it costs, when the first version launches, and what happens if the scope changes.
The contract should also say who owns the code when the app is finished. Some developers retain ownership and license it to you; others transfer ownership to you. If you own the code, you can hire a different developer later to make changes. If the developer owns it, you are locked in. For a business app, you usually want to own the code or have a license that lets you move to another developer if needed.
Ask the contract to specify what happens after launch. Does the developer fix bugs for free? For how long? Who pays for hosting? Who makes updates when your phone's operating system changes? These costs add up, so get them in writing.
Budget for the year after launch, not just the build
The cost to build an app is only the beginning. After launch, you will have ongoing costs: hosting the servers that run the app, fixing bugs that users find, making updates when Apple or Google changes their phone operating systems, and adding new features as your business grows.
Plan to spend 20 to 40 percent of the original build cost each year on maintenance and updates. If you built the app for $50,000, budget $10,000 to $20,000 per year to keep it running. Some of this is predictable (hosting usually costs the same each month). Some is not (a major operating system update might require weeks of work to keep the app compatible).
If you cannot afford the ongoing costs, you cannot afford the app. Many business apps fail not because the original build was bad, but because the business ran out of money to maintain it and the app became broken and outdated.
Know what to look for in a developer or development company
You can hire a freelancer, a small agency, or a large development company. Each has trade-offs. Freelancers are usually cheaper but may disappear or take on too much work. Small agencies are often faster and more flexible but may not have the depth to handle complex integrations. Large companies are more stable but more expensive and sometimes slower to respond.
Regardless of size, ask to see apps they have built before. Ask for references from past clients and actually call them. Ask what happens if the developer gets sick or quits — will someone else be able to maintain the app? Ask whether they use version control (a system that tracks changes to the code) and whether they write tests (automated checks that the app still works after changes). These practices matter because they make the app easier and cheaper to maintain later.
If a developer promises to build your app very fast or very cheap, ask why. Sometimes they have a good reason (they have built something similar before, or they are using a template). Sometimes they are cutting corners that will cost you later (skipping security, not writing tests, not documenting the code). The cheapest option is rarely the best option.
Frequently Asked Questions
How much does it cost to build an app?
A straightforward app for a small team might cost $10,000 to $30,000. A medium app with user accounts and connections to your existing software might cost $50,000 to $150,000. A complex app with many features might cost $200,000 or more. The price depends on what the app does, how many people will use it, and how fast you need it built. Get quotes from multiple developers before deciding.
How long does it take to build an app?
A straightforward app might take three to six months. A medium app might take six to twelve months. A complex app might take a year or more. The timeline depends on how clear your requirements are, how many changes you make during development, and how busy the developer is. Realistic timelines are cheaper than rushed ones.
Can I change my mind about features after work starts?
Yes, but changes cost money and time. Every change means the developer has to rewrite code and test it again. The contract should say how changes are handled — usually you pay extra for changes that are not in the original plan. The more detailed your original plan, the fewer expensive changes you will need later.
What if the app does not work after it launches?
The contract should say who fixes bugs and for how long. Usually the developer fixes bugs found in the first 30 to 90 days for free, then you pay for fixes after that. Make sure this is in writing before work starts.
Do I need to hire the developer to maintain the app, or can I hire someone else later?
That depends on the contract and who owns the code. If you own the code and the developer used standard tools and practices, you can hire someone else to maintain it. If the developer owns the code or used custom tools, you may be locked in. Discuss this before you hire the developer.
