Where AI actually helps a small business
And the three places it will cost you money
AI tools are good at drafting, summarising, explaining and comparing. They are unreliable at arithmetic, at anything requiring current South African tax rates, and at knowing what they do not know. Use them where a wrong answer is obvious and cheap to fix, not where it is invisible and expensive.
Who this is for: Owners who keep hearing they should 'use AI' and want to know where to actually start.
Start with the writing you already avoid
Quotes, follow-up emails, job adverts, standard operating procedures, a policy for the staff handbook. These are jobs where a decent first draft in thirty seconds beats a perfect document you never write. You are the expert; the AI is the typist who never gets tired.
Try this prompt
Draft a short, polite follow-up email to a customer whose invoice is 30 days overdue. We have a good relationship and I want to keep it. Keep it under 120 words, South African English, no American phrases.
Use it to explain things to you, not to decide things for you
Asking what a clause in a lease means, or what a term on your financial statements refers to, is a good use. Asking whether to sign the lease is not. The first is explanation, which it does well; the second is judgement about your circumstances, which it cannot have.
Try this prompt
Explain what this clause in a commercial lease means in plain English, and list the questions I should ask my attorney about it: [paste the clause].
Turn long documents into something you will actually read
A 40-page supplier contract, a municipal notice, a long policy document. Ask for a summary and the three things that could hurt you. Then read those parts properly yourself.
Try this prompt
Summarise this document in 10 bullet points, then list anything that creates an obligation, a cost, or a deadline for me: [paste the document].
Use it as a sounding board before a decision, not instead of one
Ask it to argue against your plan. 'Here is what I am thinking of doing. Give me the five strongest reasons this fails.' It is genuinely useful for finding the hole you have talked yourself past.
Try this prompt
I run a [type of business] in Amanzimtoti and I am thinking of [plan]. Give me the five strongest arguments against it, and what I would need to be true for it to work.
Know the three places it costs you money
One: arithmetic and anything involving your actual figures — it will produce a number that looks right and is not. Two: current South African tax rates, thresholds and deadlines — these change with the Budget and the model may be working from old information. Three: anything you send to a client or SARS without reading it properly, because the mistakes are fluent and confident, which is exactly what makes them easy to miss.
Before you do this
- An AI answer about SARS rules may be a year out of date and will never say so. Confirm anything with a deadline or a rand figure attached.
- It cannot see your books. If it quotes a figure about your business, it made it up.
