Here are the numbers up front, from our own pricing: an internal tool that replaces spreadsheets or paper for one core workflow typically runs $8,000–$20,000. A customer-facing app—accounts, payments, the one thing it must do exceptionally well—typically runs $15,000–$45,000. Ongoing development after launch runs $2,000–$6,000 a month if you want steady improvement.
Those are wide ranges, and the honest reason is that "an app" varies more than almost anything else a small business buys. The rest of this guide is about what moves you toward the low or high end—and whether you need an app at all.
The three tiers, and what each really is
| Tier | Typical range | What it is |
|---|---|---|
| Internal tool | $8,000–$20,000 | Replaces spreadsheets, paper, or group texts for one workflow—scheduling, job tracking, quoting |
| Customer-facing app | $15,000–$45,000 | A mobile app or web portal your customers log into, with accounts and usually payments |
| Ongoing development | $2,000–$6,000/mo | A retainer after launch: features, fixes, and support at a predictable monthly cost |
The tiers differ less in code than in stakes. An internal tool can have rough edges on day one because your own staff will tell you what's wrong. A customer-facing app can't—every rough edge costs you a customer who won't report the problem, they'll just leave.
What actually drives the price
Four questions decide most of the range:
One platform or several? A web app that works on every phone's browser is one build. Native iOS plus Android plus web is closer to three. Many local businesses that ask for "an app" are better served by a web app first—no app-store approval, no forced updates, one thing to maintain.
Do people log in? Accounts mean stored personal data, password resets, and security obligations. Payments raise the stakes again. Each is routine engineering, but it's real scope—this is usually the line between the two tiers.
What does it connect to? An app that talks to your calendar, your payment processor, and your accounting software is doing three integrations, and each one is negotiated with someone else's system. Integrations are the most commonly underestimated line item in any quote.
How polished must launch day be? Software can be genuinely done at 80% polish if the core workflow is solid. Chasing the last 20% before anyone has used it is the most expensive way to find out which 20% mattered.
The question before the question: do you need an app at all?
Often, no—and it's better to hear that from a developer before you spend. If your goal is being found and contacted, a strong website does that for a fraction of the price (here's what websites cost). If your goal is automating repetitive office work, an automation project is usually cheaper and faster than a custom tool.
An app earns its cost when there's a workflow at the center of your business that generic software genuinely can't handle—when you're running the operation out of spreadsheets that only one person understands, or your customers need to log in and do something, not just read.
How to keep a first version affordable
The single best cost control is scope discipline: build a lean first version that does one thing end-to-end, ship it to real users, and let their behavior—not a brainstorm—decide round two. In practice that means:
- One core workflow, complete and reliable, instead of five half-built ones.
- Boring choices everywhere else: standard log-in, standard payments, proven components.
- A weekly working build you can click through, so surprises surface in week two, not month four.
This is also a useful filter when comparing quotes. A developer who pushes back on your feature list before quoting is protecting your budget. One who quotes the everything-app without questions is quoting a number, not a plan.
What ongoing costs look like
After launch there are two separate costs people tend to blur together. Running costs—hosting, app-store fees, third-party services—are typically modest for a small-business app, on the order of tens of dollars a month, and any honest quote discloses them up front. Development costs are a choice: a finished internal tool can coast for years, while an app that's central to growth usually justifies the $2,000–$6,000/month retainer to keep improving.
Either way, insist on owning everything—the code, the accounts, the app-store listings. Whoever builds it should be easy to keep and possible to replace.
