Ask me how much a custom web app costs and I'll ask you back: how much does a car cost? How much is a house? How much is a trip to Italy?
It all depends on what you want. That's not a dodge — it's the truth, and anyone who gives you a flat price before understanding your business is either guessing or planning to surprise you later. There's no “give me this amount of money and you'll get anything you want.” That's not how software works.
But I also know why you searched this question: you want real numbers before you talk to anyone. So I'm going to give you mine — what I charge, what pushes the price up, when you shouldn't build an app at all, and the two expensive myths I keep watching business owners fall for.
What actually determines the price
The cost of a web app comes down to a few honest questions:
- Do you want a template, or a fully custom build?
- What functionality does it actually need to do?
- What are your business rules — the specific ways your business works that the software has to follow?
That last one is the sleeper. Two apps can look identical on the surface, but if yours has to follow complex rules about who can see what, when payments fire, or how bookings cascade, the build is a different animal. If you're still fuzzy on the difference between a website and a web app, I broke that down in what's the difference between a website and a web app — read that first if you're not sure which one you're actually pricing.
My real starting number: $6,000
I start custom web app projects at $6,000. Here's why that's the floor and not a penny lower.
If you want a web app, you don't actually want “just a login page for users.” You want a secure way to collect user information. You want functionality that works. You want a scalable site that also has SEO built in — because an app nobody can find is a very expensive secret.
At $6,000 you're getting a solid foundation — including the ability to do things yourself without calling the developer every time. Modifying users, viewing user information, managing your own data. A build that makes you dependent on the developer for every small change isn't a foundation; it's a leash.
What pushes the price up from there
From that $6,000 floor, here's what actually moves the number:
- Third-party integrations. Connecting your app to warehouses, CRMs, calendars, or anyone else's system takes real engineering — and it's where cheap builds break first.
- Performance optimization for background tasks that run heavy data manipulation. If your app crunches serious data behind the scenes, it has to be built for it.
- Payments. Collecting money means security, compliance, and edge cases.
- Custom pipelines and stacked functionality. Every workflow your business needs is something that has to be designed, built, and tested.
None of this is padding. It's the difference between an app that demos well and an app that runs your business.
When I tell people NOT to build a web app
Here's something that might sound strange coming from someone who builds web apps for a living: most of the time, you don't need one yet.
You could often go simpler — a static site with an internal tool connected to it. We don't just build websites; sometimes the right answer is a simple desktop app that takes care of your needs long-term. Even payments don't automatically mean you need a full web app: if you don't need to collect heavy information and there isn't a lot of business logic, a well-built static site handles it fine.
The signal that you've outgrown the simple option is business rules: when your operations have rules that spreadsheets, plugins, and off-the-shelf tools keep fighting against, that's when custom makes sense. Until then, save your money — I'd rather tell you that now than invoice you for something you didn't need. (That's the same math I walk through in how much a website costs — match the build to the role it plays in your business.)
The monthly cost nobody budgets for
A web app is not “build once and walk away.” My monthly maintenance covers the server itself, SSL certificates, monitoring the logs and performance, and small updates to the site — included, so the customer isn't billed again for every little thing. In reality, clients save money on the monthly, because the alternative is paying à la carte every time something needs attention.
And here's the horror story that plays out in my inbox over and over. New customers ask what my builds cost, I tell them, and they say: “that's expensive.” Dig one layer deeper and it's never really about my price. It's because they already paid someone — a college student, a friend-of-a-friend, an offshore freelancer — who did cheap, unreliable work and then disappeared. No support, no care, not one follow-up. Now their site is broken or embarrassing, and when they hear my quote, they're mentally adding it to what they already spent.
I understand why they do that math. But the real lesson is brutal: the cheap build wasn't cheap. It cost everything they paid for it, plus everything it takes to do it right the second time. Hiring a professional team that develops the tools you need and takes care of your site is genuinely expensive — my whole model is making that simpler and less expensive with the same level of care. If you're comparing developers right now, here's what you should expect from anyone you hire before you sign.
How the process actually works
When someone comes to me, we meet or jump on a call and I interview them — because what you want and what you need are two different things. You might tell me you want x, y, and z. But what your business needs right now, and can afford, is x and y. The z can come later, when the business is on its feet and making money. I put that in a phased roadmap so you can see the vision — and see that I'm not trying to grab the money and disappear. I'm trying to be part of the journey.
The practical mechanics:
- Phase one takes one to three months, depending on scope and urgency.
- Payment is flexible — typically 50% up front and 50% at completion, or a 50/20/30 split. We're flexible; we just prefer everything agreed before the project starts.
- Everything gets written out in plain English — what each piece is for, why you need it, how it works with everything else — so you know exactly what you're getting.
- At delivery, we walk through a checklist together, showing you how everything works and that everything we agreed on is there and working.
- You get one month free after launch — good-faith monitoring, so if something unforeseen breaks, we're there.
The two myths that cost business owners real money
The offshore bargain
A company once took my free consultation, then went with an offshore team instead — about five to six times cheaper. That team broke a critical integration with the warehouse the customer used to ship supplies to their own customers. Then they said “it's not our fault” and stopped helping entirely. The company came back to me, and we fixed it — but they paid for that build three times: once for the cheap version, once in broken operations, and once to make it right.
The AI bros
AI is good — if you use it properly, you're an engineer, and you have a team that knows what it's doing. It's dangerous in the hands of people undercutting professional teams by having AI do everything, 24/7, with no human oversight. When it's your customers' data, your business logic, and your financial flows, that's not a corner to cut. Apps built this way ship with vulnerabilities and store sensitive information in the open — in environments anyone can access.
Here's the test I give every business owner: if somebody on the street offers you a Gucci bag for $100, you know something's wrong with that bag — because there's no way a real one costs $100. Apply the same logic to software quotes.
So what should you budget?
If your business genuinely needs a custom web app, real builds start at $6,000 for a secure, scalable foundation with self-serve admin, and grow from there with integrations, payments, heavy data work, and custom pipelines — delivered in phases, so you fund z after x and y start paying for themselves. That's the honest math behind our custom web and cloud builds, and every tier is priced publicly so you don't have to “contact us” just to see a number.
And if you're not sure whether you need an app at all — ask. Telling you “not yet” is free, and it's a much better first conversation than fixing a $100 Gucci bag. Tell me what you're building →
