For most local businesses, a website is enough. If customers need to find you, see what you do, and call, book, or buy, a well-built site handles all of it: in our pricing, a custom marketing site is $3,500–$8,000 and a customer-facing app is $15,000–$45,000. An app earns that difference in two situations: the same people use it often, or it has to do something only a phone app does well.
That's the whole answer in two sentences. The rest of this post is how to tell which side you're on, plus a middle option that gets skipped in most of these conversations.
What's the actual difference?
People say "app" to mean three different things, and the price depends on which one you mean.
| Website | Web app | Mobile app | |
|---|---|---|---|
| What it is | Pages people read | Software in the browser: logins, accounts, data | Software installed from the App Store or Google Play |
| How customers get it | Search or a link | Search or a link; can be added to the home screen | Find it in a store, download, install |
| Built for | All devices at once | All devices at once | iPhone and Android, often separately |
| Updates | Live the moment you publish | Live the moment you publish | Go through store review, then users update |
| Typical cost (our pricing) | $3,500–$8,000 marketing site; $6,000–$15,000 with booking or e-commerce | $15,000+ as a custom web application | $15,000–$45,000 customer-facing app |
| Best for | Being found and contacted | Customers or staff who log in and do something | Frequent use and phone-only features |
The column most owners haven't heard of is the middle one, and it's where a lot of "we need an app" projects should actually land.
When a website is enough
If your customers come to you once in a while, a website is almost certainly the right call. A plumber, a dentist, a restaurant, a law office: people look you up, check that you're real, and get in touch. Nobody installs an app for a business they visit twice a year. Asking them to is a hurdle between them and the phone call.
A website also handles more than people expect. Online booking, deposits, payments, a product catalog, and a customer login can all live on a site. If the thing you're picturing is "customers can book from their phone," that's a booking site, not an app, and it costs a fraction of one (here's what websites cost).
When does a mobile app earn its cost?
An app is worth considering when at least one of these is true:
- The same people use it every week or more. Loyalty programs with real regulars, a gym's class booking, a service your customers check constantly. Frequent use is what makes the download worth it to them.
- It needs the phone's hardware in ways a browser handles poorly. Tracking location in the background, working with Bluetooth devices, heavy camera use, or working properly with no signal.
- Your own staff use it in the field. Crews filling out job forms, taking photos, and collecting signatures on site. If they work where cell service is unreliable, and parts of the Adirondacks qualify, offline support matters. That tends to favor a real app.
- Being in the app store is part of how customers expect to find you. For some consumer businesses it is. For most local service businesses it isn't.
If none of those fit, an app is probably an expensive way to do what a website already does.
The middle option: a web app
A web app is built like a website and works like software. Customers log in, see their account, place an order, check a status, upload a document. There's no store and no download: it works on any phone or computer from one build, and updates go live immediately.
Two details close most of the old gap with installed apps. First, customers can add a web app to their home screen, where it opens full-screen with its own icon. Second, since iOS 16.4, iPhones can receive push notifications from web apps that have been added to the home screen. The catch is that people have to add it first, and many never do. So if notifications are central to your idea, factor that in honestly.
Where a web app still falls short is the hardware list above: background location, Bluetooth, and serious offline use. If your idea depends on those, you need a real app. If it doesn't, a web app often gets you most of the value for one build instead of two.
On the build price, a web app and a mobile app start in the same place in our pricing, because the work behind the screen (accounts, data, payments) is much the same. The savings come after launch: one version to keep updated instead of two, no app store review, and no yearly developer fee.
What each one costs to keep running
The build price isn't the whole bill.
- A website needs hosting, updates, and someone to call when something breaks. It's the cheapest of the three to keep alive (what maintenance should cost).
- A web app adds the server side that stores your customers' accounts and data. Cloud hosting for a small-business app typically runs $25–$200 a month, depending on usage.
- A mobile app has the same hosting plus store costs. For example, Apple's developer program is $99 a year. The bigger cost is less visible: Apple and Google release new phone software every year, and apps need updates to keep working well on it. An app nobody updates slowly gets worse, even if you never change a thing.
A three-question test
- How often will one customer use it? Monthly or less: website. Weekly or more: keep going.
- Does it need something only an installed app does well? No: a web app will likely do. Yes: an app is on the table.
- Could a website prove the idea first? Usually it can. If customers use the web version heavily, you'll build the app later knowing exactly what it needs, and that makes it cheaper (here's what apps cost, tier by tier).
If you're still unsure, that's what a scoping conversation is for. Our app development service starts with a free one, and "a website will do" is a perfectly normal answer for us to give. Better to hear that before you spend $15,000 or more than after.
