I’ve spent the best part of 20 years doing the books for farmers, tradies, and small business owners across New Zealand. So when something new turns up promising to save you time and money, my first thought usually isn’t excitement. It’s: right, what’s the catch? Who’s going to get burnt?
AI is the latest of those, and honestly, most of the hype around it is rubbish. But underneath the noise there’s a genuinely useful tool here — if you know which jobs to give it, and which ones to keep it well away from.
So let me walk you through it: five jobs I’d happily hand to AI, and the hard nos I wouldn’t touch.
Five jobs I’d happily hand to AI
1. The emails you keep putting off
Every business owner has a list of messages they’re avoiding. The overdue invoice chase. The reply to a shirty customer. The quote follow-up that’s been sitting there for a fortnight.
This is the safest and most useful thing AI does. You tell it the situation and the tone you want, and it gets you from a blank screen to a near-finished draft in seconds. You read it, fix the bits that don’t sound like you, and send it.
It’s not writing better than you. It’s getting you past the bit where you stall. I’d let it near this all day long.
2. Turning what you know into content — with a hand firmly on the wheel
You’ve been in your trade for years. You know how things work, you know your customers, and you know what they need to understand. That knowledge is the raw material for the blog post, the website, the newsletter you keep meaning to start.
AI is good at this — but only as the writer, not the expert. The expertise has to be yours. If you ask it to invent content about something it doesn’t actually understand, you’ll get something that sounds confident and is quietly wrong.
Talk through what you know, let it do the shaping, and the result is genuinely yours.
3. Making sense of a long document — to understand, not to decide
Plenty of business owners are buried in reading. Supplier contracts, insurance policies, a new IRD rule, a lease you’re expected to have an opinion on by Friday.
You can paste the document in and ask for the key points in plain English, or what to be wary of before you sign. That can save you real time.
But here’s the line, and it’s an important one: use it to understand the document faster, never to make the decision. It can misread things, and it knows nothing about your actual situation, so it can get it wrong. Get on top of the document with it — then take your real questions to your accountant, your lawyer, or another professional.
4. Writing your social posts
Marketing is a job most small business owners quietly dread. You know you should be posting on Facebook, Instagram, or wherever your customers are — but actually sitting down to write the things is miserable, so it doesn’t happen. Then six weeks go by and the page looks dead.
This is a genuinely good use for AI. You take one idea — a job that’s finished, a question a customer keeps asking, a seasonal reminder — and AI turns it into a handful of posts in your voice. A finished fencing job becomes a before-and-after caption. A common “do I need to sort this before winter?” question becomes a helpful post that quietly shows you know your stuff.
The trick is the same as before: give it the substance, let it handle the wording. You’ll get tens of posts out in one afternoon instead of staring at an empty box every week. You still need to read each one and make sure it sounds like you, not a marketing robot. But a page that’s actually alive does quietly bring the work in.
5. The wording you type 40 times a year
Every business has writing that repeats. The standard quote intro, the job-done text, the same explanation you’ve typed 200 times before. Once you’ve shown AI your style, it can churn out consistent versions of these quickly.
For a business with no admin person and no spare hours, this is where the time actually adds up. Not one big saving — 10 minutes off a dozen small jobs a week.
The lines I definitely wouldn’t cross
Here’s the part the hype merchants skip. As an accountant, these are the hard nos.
Never let it do your numbers. Your GST, your tax, your payroll — anything with a dollar sign. It’s confidently, plausibly wrong often enough that I wouldn’t trust it with a single calculation without checking it myself.
Never paste in anything you wouldn’t email. Client details, IRD numbers, personal information. Remember: this is not a vault.
Never let it replace the advice. It’s not your accountant and it’s not your lawyer. It’s the first draft of a decent explainer. The judgment and the signature stay with you.
So where does that leave us?
AI isn’t magic, and it isn’t a threat. It’s a keen junior who’ll knock out a quick first draft and occasionally get things badly wrong. Use it for the right handful of jobs, with you still holding the pen, and it’ll quietly give you a few hours back each week.

Until next time, keep it boring.
