A garage owner rang us this spring. A competitor two streets away had launched an app and he wanted to know what one would cost. We asked one question first: how often does the same customer come through your door? Twice a year, he said — the annual test and a service. After that the conversation was not about apps any more.

That one question decides more than any feature list. Here is how to answer it for your own business, and what the honest alternatives are.

What an app genuinely does that a website cannot

Four things, really. It sits on the home screen, so opening it is one thumb-tap rather than a search. It can send a notification to a locked phone. It works with no signal at all — useful in an underground car park or on a delivery round out of town. And it reaches deeper into the phone: scanning barcodes continuously, tracking a route in the background, holding a payment card.

Everything else people ask for — ordering, booking, a loyalty balance, a menu, photos, a form — a mobile website does just as well. If your whole wish list sits in that second group, you are asking for an app because it feels more serious, not because you need one. That is an expensive feeling.

The frequency test

Ask how often one customer touches your business in a normal month.

Weekly or more — a lunch spot, a gym, a hairdresser with regulars, a wholesaler whose buyers reorder — and an app can earn its keep. People will accept the install because they will use it dozens of times.

Once a month — borderline. It depends on whether the app saves real effort every single time.

A few times a year — a garage, a dentist, a plumber, a wedding venue — no. Nobody keeps an icon on their home screen for something they use in March and September. They will install it, use it once, and delete it when the phone runs out of storage. You will have paid for a channel that reaches nobody.

What an app costs after it is built

The build price is the part everyone quotes. The running cost is the part that surprises people.

You need a developer account with both stores — Apple charges roughly €99 a year, Google a one-off of about €25. Every release goes through review, which takes hours to days and occasionally comes back rejected over something small. Phone operating systems change once a year, and an app nobody touches will eventually stop working or stop being accepted. Budget for a small maintenance release every few months even if you change nothing.

And then the hardest cost of all: getting it installed. A website you can send by link, by text message, by a QR code on the counter, by a Google result. An app needs a deliberate decision, a store password and 80 MB of someone's phone. In our experience that is where most small-business apps quietly fail — not in the build.

The middle road: a website that behaves like an app

There is a version in between that most owners are never offered. A modern mobile website can be saved to the home screen with its own icon, open full-screen without a browser bar, remember who you are and keep working on a poor connection. In the trade it is called a progressive web app — in practice it is your website, with a shortcut.

You keep the link, the Google listing and one codebase for both iPhone and Android. Notifications are possible but fiddlier, especially on iPhone, and people have to add it deliberately. For a loyalty card, a repeat order, a booking or a menu, it is usually enough — and it costs a fraction.

What to do this week

  • Open your website statistics and write down what share of visits come from a phone. If it is over half — and it usually is — your mobile site is your shopfront, app or no app.
  • Count how many times your best customer bought from you in the last twelve months. Put that number on paper before anyone quotes you for an app.
  • Take out your own phone, book or order from your own site, and time it. Anything over ninety seconds is a fix that pays back faster than any app would.

If you work through that and the frequency really is there, an app is a reasonable next step — and we are happy to think it through with you at ITSysPro before you spend anything.
