Ask five developers what a custom app costs and you’ll get five very different answers. That’s not because anyone is being cagey. It’s because “an app” can mean anything from a simple booking form to a full platform with logins, payments, and reporting. Here’s what actually drives the price, so you can have a clearer conversation.
The biggest cost factors
- Number of features: every screen, form, and report adds work
- Who uses it: just your staff, your customers, or both, each with different permissions
- Logins and security: accounts, roles, and protecting sensitive data
- Integrations: connecting to payments, accounting, email, calendars, or existing software
- Web, phone, or both: a web app that works on phones is usually less expensive than separate phone apps
- Design polish: simple and functional costs less than highly customized
- Data migration: moving existing spreadsheets or records into the new system
Ongoing costs to plan for
- Hosting and security updates
- Bug fixes and small improvements
- Support when something goes wrong
- New features as your business changes
A good estimate spells these out, not just the build price.
How to keep the first version affordable
- Solve one problem first. Pick the most time-consuming task and build only what’s needed for it.
- Skip nice-to-haves. Keep a list for later instead of building them now.
- Use proven building blocks for common pieces like logins and payments instead of building them from scratch.
- Launch, learn, then grow. Real use shows you what actually matters.
Questions to ask before you build
- Who owns the code and the data?
- What happens if I want to change developers later?
- What’s included in ongoing support?
- How will my team be trained?
- What’s the plan if we need to add features?
Is an off-the-shelf tool cheaper?
Often, yes, at least at first. If an existing product fits how you work, use it. Custom makes sense when your process is unique or existing tools cost you time by forcing workarounds. I wrote more about that decision in when to replace spreadsheets with a custom app.
Questions I hear a lot
Can you give a rough price without a meeting?
Not responsibly. A short conversation about what the app needs to do makes a real estimate possible.
How long does a first version take?
Small, focused apps can be built in weeks; larger platforms take longer. Starting small keeps timelines short.
If you want a second set of eyes
If you have an idea and want an honest take on what it would involve, I’m glad to talk it through. Here’s how I approach custom apps and platforms.
