AI for a one-person trade business: a worked example

This is an illustrative example, not an interview. “Mike” and “ABC Electrical” are placeholders. The situation is real and common, the tasks are real, and the arithmetic is shown so you can put your own numbers in. Nothing here is a measured result from a specific company. When Torus publishes a case study, it names the company and prints their figures.

With that said, this is the shape of the problem for tens of thousands of UK sole traders, and it is a better place to start than a tool list.

The business

Mike is an electrician working domestic jobs, mostly rewires, consumer unit replacements, EICR inspections and the steady drip of small callouts. He works alone on site. Two part-time people help: one doing books a few hours a week, one who answers the phone when she can.

He is good at the electrical work. Everything else happens in the van, at lunch, or after dinner.

Where the day actually goes

The trap in a business like this is that the admin is invisible. It never gets a line in the accounts because it is done in gaps.

Task	Roughly
Missed calls, returned later	30 to 60 min/day
Quotes written up	3 to 5 hours/week
Invoices, and chasing them	2 to 3 hours/week
Scheduling and rescheduling	3 to 4 hours/week
Certificates and job paperwork	2 to 3 hours/week
Asking for reviews, updating listings	rarely happens
Records for tax	a weekend, quarterly

That is comfortably a day a week, and it is unpaid.

The one that costs real money

Everything above is annoying. Only one of them loses revenue directly.

When the phone rings while Mike is under a floor, it goes to voicemail. Some of those callers leave a message. Some ring the next electrician on the list. He never finds out which.

That is the number to attack first, and the arithmetic is worth doing properly with your own figures rather than accepting anyone’s benchmark:

Calls missed per week            × how many were new work
× your conversion rate on new enquiries
× your average job value
= the weekly cost of not answering

For a domestic electrician with a mid-hundreds average job value, recovering even one job a week is a materially different year. That is the case for automating the phone before anything else, and it does not depend on a productivity percentage.

The seven jobs AI can take

Roughly in order of what to try first.

1. Answering the phone. An AI receptionist takes the call, captures name, address, what is wrong and how urgent, and texts Mike a summary. It does not diagnose and does not quote. The purpose is that a new caller speaks to something rather than nothing.

2. Turning a job into a quote. Mike dictates two sentences in the van. The assistant produces a formatted quote against his standard prices. He checks and sends. This is the task where AI is closest to genuinely good, because the input is a description and the output is a document.

3. Invoicing on completion. Most trade accounting software will now draft the invoice from the job record. The saving is not the typing; it is that invoices go out the same day rather than at the weekend, which moves cash in sooner.

4. Chasing payment. A polite scheduled reminder sequence, automatic. Most sole traders under-chase because chasing feels rude, and a system has no such feeling.

5. Asking for reviews. A message after payment, with a direct link to the Google Business Profile. This is the highest-leverage marketing available to a local trade and almost nobody does it consistently, because the moment to ask is exactly when you have moved on to the next job.

6. Scheduling. Reading the diary, offering real slots, confirming and sending reminders. Reduces the no-shows and the four-message exchange about Thursday.

7. Paperwork and records. Pulling receipts and job data into something an accountant can use, and drafting the routine parts of certificates. Not signing them. An electrical certificate carries professional and legal responsibility, and that stays with the person qualified to hold it.

Where the productivity number comes from

A realistic target for a business like Mike’s is 30 to 40% of the admin time back, not 30 to 40% of the working week. The distinction matters, and content that blurs it is selling something.

If admin is a day a week, that is three to four hours returned. Two ways to take the gain:

• Sell it. Three more hours on site is three more chargeable hours.
• Keep it. Three hours not working on a Sunday.

Both are real. Only the first appears in the accounts, which is why the second gets dismissed and then quietly decides whether someone stays in business.

The cash effect that is usually larger than either: invoices going out on the day instead of at the weekend. For a business with weeks of work in progress, pulling that forward is a one-off cash improvement worth more than the hours.

What to be careful about

Never let it quote a price it made up. Quoting from your own rate card is fine. Inventing a number is how you end up honouring a price you would not have given.

Never let it sign or certify. Notification and certification carry responsibility that does not transfer to software.

Tell people they are speaking to an AI. For a local trade the relationship is the asset, and being caught pretending is more expensive than any hours saved.

Customer details go in. Names, addresses, phone numbers, sometimes photos of a property. That is personal data, so check your vendor contract, and take twenty minutes on whether you need a DPIA. For most small trade setups the answer is no, but the note saying you checked is the thing worth having.

What Mike should do first

One thing, two weeks, a number.

Answer the phone. It is the only item on the list that directly loses revenue, it is measurable in a fortnight, and it needs no change to how he works. Count the enquiries that reach him during the trial and compare it with the fortnight before.

If that works, invoicing and review requests next, because they compound: paid sooner, and a steadily better local listing.

Everything else can wait. The method behind that sequencing is in where to start with AI: highest cost, lowest judgement, one at a time.
