Custom software for small businesses, now that AI made it affordable

For years, small businesses had two choices. Use off-the-shelf software that does 70% of what you need and annoys you about the rest, or pay for custom software that cost more than the van.

AI has quietly opened a third option. A good vibe coder can now build a tool shaped exactly around how your business works, in days rather than months, for a price that makes sense for a business your size.

Signs you need something custom

You don’t need custom software for the sake of it. You need it when you notice:

• The same information typed in twice, from one system into another, or from paper into a spreadsheet.
• A spreadsheet only one person understands, who is also the person who goes on holiday.
• Customers ringing to ask things a web page could answer: prices, availability, “where’s my order”.
• Three apps doing one job badly, each with its own subscription.
• A process that lives in someone’s head and goes wrong every time they’re off sick.

If two or more of those sound familiar, there’s probably a tool worth building.

Twelve tools worth having built

Facing your customers

1. A quote calculator that gives an honest price range in thirty seconds, instead of a callback in three days.
2. A booking page that understands your real rules: buffer times, deposits, staff who only do certain jobs.
3. An order tracker so customers can check progress themselves instead of ringing.
4. A menu or price list you can update from your phone in a minute.
5. A loyalty or referral tracker that doesn’t need a plastic card or a third-party app.

Running the place

6. A staff rota that knows who can work when, who’s trained on what, and who swapped with whom.
7. A stock tracker that warns you before you run out, not after.
8. A job sheet app for trades: photos, notes, materials used, the customer’s signature, sent straight to the office.
9. A daily checklist for opening, closing or cleaning, with a record of who did what.

Seeing what’s going on

10. A dashboard that pulls your sales, bookings and costs into one screen you’ll actually look at.
11. Automatic reports that land in your inbox every Monday morning without anyone building them.
12. A tidy customer list that merges the contacts scattered across your email, phone and booking system.

None of these are moonshots. That’s the point. Each one saves a few hours a week, and a few hours a week adds up to weeks a year.

How to get one built

1. Write down the problem, not the solution. “We spend six hours a week answering ‘is my car ready?’ calls” is a better brief than “we need an app”.
2. Get a few makers to pitch. Describe the problem and ask makers to pitch with how they’d solve it and what it would cost. Favour the ones who’ve built something similar before. A maker who’s built a booking tool will be faster and better at yours.
3. Start small. Build the one feature that saves the most time. Use it for a month. Then decide what’s next.
4. Pay in milestones, held in escrow. You only release payment for work you’ve seen and are happy with.
5. Own everything. The code, the hosting and the accounts should all be in your name. Our hiring guide has a handover checklist.

What it’ll cost

It depends on the size of the job, but most of the tools above fall into the “few days to two weeks” range for a capable vibe coder. Our guide on what it costs to hire a vibe coder breaks down the price and the running costs, so you can sanity-check any quote.

The useful comparison isn’t against other quotes, though. It’s against what the problem costs you now. If a tool saves five hours of staff time a week, it pays for itself surprisingly quickly.

Or start with something already built

Sometimes the tool you need already exists, built by someone who had the same problem. Browse projects on Vibers before commissioning anything. You might find a template that gets you 90% of the way for a fraction of the price, plus a maker who’d happily adapt the last 10% for you.
