Is there one job in your business where AI is actually worth trying — and if so, which one?

That is the only question this answers. You finish with a written, dated answer and the reasoning behind it.

Two hours, across one day and a night. You write down where your week actually goes — from your records, not your memory — read nine straight judgements about plumbing, score your own list, run the top three past a safety check, and write one page you keep.

If you cannot spare a whole evening there is a twenty-minute route in the opening pages. And if your invoicing is already handled, those lines score low and the book sends you elsewhere in your week.

Most AI advice for small businesses is written for offices, by people with something to sell at the end of it. This names no software, recommends none, and has nothing to buy afterwards — no affiliate link, no upsell, no follow-up.

“Not yet” is a real answer. If you finish and decide against it, the book has done its job — it says so on page ii.

For owner-operators: sole traders, two trucks, four trucks, still on the tools and still doing the paperwork in the evening. Refrigerant work requires EPA Section 608 certification, which a plumbing licence does not confer — the book treats it as a hard stop.

Includes The Retirement Question — what a replacement market actually means for this trade, and where the EPA Section 608 boundary sits.
