What is AI good for if you're a tradesman?

AI is genuinely good at the writing that eats your evenings - turning rough site notes into a quote, chasing people who haven't paid and answering the same enquiry for the twentieth time - but it has no business near your prices, the regulations or your certificates.

It helps to know how much time is at stake. A micro business affected by late payment spends around 75 hours a year chasing it. That figure comes from research London Economics carried out for the Department for Business and Trade, published in July 2025, and it only counts time spent chasing unpaid bills, not the invoicing itself.

Seventy-five hours is roughly two working weeks of evenings. The encouraging part is that a good share of those hours isn't an AI problem at all. It's a setting in software you already pay for.

Start with the software you're already paying for

Before you buy anything, have a look at the payment reminder settings in your job management software. Tradify, to take one example, describes on its invoicing page a payment reminder feature that sends emails "that will automatically follow up on invoices that haven't been paid". Check whether it's included in your plan and whether it's switched on - it's easy to miss.

The same goes for the links between your systems. Tradify runs a two-way sync with Xero. A sync is like two diaries that copy each other: change one and the other updates. In Tradify's words, "whatever you update in Tradify will update in Xero and vice versa", covering invoices, bills, payments, suppliers and customers. Commusoft publishes a longer list of connections, including Xero, QuickBooks, Sage, Stripe, GoCardless, Google and Outlook calendars, and Zapier, a service that passes information between apps that don't talk to each other directly.

If working out which of those settings and connections you've got, and which are switched on, is the bit you'd rather not do, we're happy to go through it and set up the reminders and connections for you.

Why "we'll plug AI into your job software" deserves a question

Software vendors aren't always precise about what their connections can do, so it's worth being precise for them. Many programs have what's called an API. Think of it as a back door that other programs are allowed to knock on to read or add information. A Zapier connection or an accounting sync isn't the same as that door being open to anything you like.

Commusoft's own developer site says clients building their own internal applications need "an appropriate subscription", and marks access for third-party partners as "coming soon". We couldn't find any published API documentation on Tradify's own site at all. So if someone offers to wire an AI assistant straight into your job software, it's fair to ask them to show you the vendor's documentation for it before you pay.

The evening job is mostly writing things down

This is where AI genuinely earns its place, and the pattern is consistent: the work is typing, not thinking.

You come off site with notes. "CU full, needs 10-way, two RCBOs, spur for the kitchen island, access round the side gate, wants it done before the 14th." That has to become a paragraph a customer can read and say yes to. It takes twenty minutes because you're tired, and on some nights it doesn't happen at all.

Handing those notes to an AI model and getting back a written quote is the single most useful thing on this list. A model is the engine behind tools like ChatGPT and Claude: you give it text, and it writes text back. You don't even have to type the notes. Voice mode in the Claude apps is available on every plan, including the free one, on mobile, desktop and web, though it's still labelled beta. You can speak the notes in the van and tidy the quote at the kitchen table.

The same approach covers the rest: the follow-up on a quote nobody chased, the reply to the latest person asking whether you do EICRs, and the job sheet written up properly rather than as four words and a photo. None of it is clever, but all of it stacks up.

If you'd like quotes and follow-ups to come out of your notes without you copying and pasting between apps, we can set up that automation so the draft is waiting for you to check.

Where AI doesn't help, and where it could get you into trouble

Anything that needs physical judgement is out. It hasn't seen behind the plasterboard, it can't smell gas, and it has no idea whether those joists will take the load.

Anything where being wrong about a regulation matters is riskier still, because the model will be confidently wrong rather than saying it doesn't know. Consider what it would have to keep straight. The wiring regulations move: the IET gives 15 October 2026 as the end date for Amendment 3:2024 to BS 7671 (the Brown Book), with Amendment 4:2026 (the Orange Book) replacing it and installers allowed to work to either edition up to that date. Meanwhile Approved Document P, which covers electrical safety in homes, is the 2013 edition and hasn't changed since. A model has no reliable way of telling you which version of which document it's quoting back at you, and it won't flag the difference.

The consequences land on you, not on the software. Under a competent person scheme you self-certify: GOV.UK says a registered installer "can self-certify that their work complies with building standards", they'll "tell your local authority about work on your behalf" where that's needed, and the customer gets a certificate "within 8 weeks of completion". That's your registration on the paperwork. On gas the line is firmer still. HSE states that "anyone employed to work on gas appliances in domestic premises must be a Gas Safe registered engineer and competent in that area of gas work", and it warns that breaking the gas safety regulations "could result in a substantial fine and/or a custodial sentence".

So use it for the wording of a quote, and not to check whether a job is notifiable.

Keep it away from your prices

AI doesn't know your merchant discount, your travel time, what that customer was like last year, or that the last two jobs on that street both turned into three days. It'll still give you a number, because it always gives you a number, and the number will look believable.

Let it write the description and the terms, and put the figure in yourself.

Scheduling and records help, but less than they sound

Rearranging a day around a cancellation is mostly a people problem. AI can draft the six messages to the six customers who might be able to move, but it can't make any of them answer the phone. That's worth having, but it saves minutes rather than evenings.

Records are worth more, with one condition. Being able to ask a question in plain English and get back the certificate from a job three years ago is genuinely useful, but only if the certificate is stored somewhere a computer can read. If your records live in a WhatsApp thread and the glovebox, getting them filed is the real project, and AI is the part you add afterwards.

Work it out using your own hourly rate

Take what an hour of your time is worth on the tools, count the evenings you spend on paperwork honestly for a fortnight, and multiply. That's the figure that matters for your business.

The 75 hours at the top of this page is an average of what business owners told a survey, not a stopwatch reading, so your own count is the better guide.

For a sense of whether late payment is likely to be your problem: in the Longitudinal Small Business Survey figures reproduced in that report, 10.1% of construction SMEs called late payment a big problem and 31.9% a small one.

What we'd suggest doing first

Three things, in this order.

First, turn on the automatic payment reminders in the software you already have. If it's in your plan it costs nothing extra, and it could well be the biggest single saving on this list.

Second, pick one writing job - quotes or follow-ups, not both - and try it with an AI tool for a month. Keep your notes rough, and judge it on whether the quotes actually go out on the day of the job.

Third, leave it there for a while. Don't let it near a regulation, a price or a certificate. That might sound like a small result, but an hour or two of your evenings back each week, from one thing that reliably works, is a better start than a big system nobody uses.

If you'd like to see what else can be taken off your plate, there's more on what we set up for small businesses and on what it costs. And if you'd rather someone else set up the reminders and the quote drafting, we're happy to do that for you.
