What AI can actually do for your small business (and what it can't)

Every week someone asks me whether they should be "using AI" in their business. Usually they've seen a video promising that AI will run their whole company while they sleep. Then they ask me what button to press.

So let me save you some time. Here's what AI genuinely does well for a small business right now, what it does badly, and what none of the videos mention.

Where AI actually earns its keep

Writing that you'd otherwise avoid. Quotations, follow-up emails, product descriptions, a polite reply to a difficult customer. If you run a shop or a service business, you write more than you think, and most of it is repetitive. Tools like ChatGPT or Claude will draft these in seconds. You still read and fix the draft — but fixing is faster than starting from a blank page.

Making sense of documents. Paste in a long contract, a tender document, or a supplier's price list and ask questions about it. "What are the payment terms?" "Which of these items got more expensive since last quarter?" This alone is worth the effort of learning to use these tools.

Customer messages in better English (or better Bemba, or better Nyanja). AI is surprisingly good at adjusting tone. Rough note in, professional message out. For anyone doing business across languages, this is quietly one of the most useful features.

Basic bookkeeping questions. Not doing your books — but explaining them. "What does this VAT rule mean for a business my size?" gets you a decent starting point before you talk to an accountant. Starting point. Not a replacement.

Where it will waste your money

"AI will run my marketing." It will generate fifty generic posts that sound like every other business's fifty generic posts. Customers can smell it. What works is you deciding what to say and using AI to say it faster.

Anything where a wrong answer costs real money. AI tools confidently make things up. They'll invent a tax rate or misquote a law without blinking. Never act on an AI answer about money, law, or contracts without checking the actual source.

Replacing a person you haven't hired yet. If you don't understand a job well enough to check the work, you can't supervise an AI doing it either.

What it costs

The free versions of the major chatbots are genuinely enough for most small businesses. Paid plans run around $20 a month and are worth it roughly when you're using the tool daily. Data is the real cost consideration here — these tools are chat-based and light, but the habit of using them adds up on a bundle.

Where to start this week

Pick one repetitive writing task you do — quotations are perfect. Write your next one the normal way, then ask an AI to draft the same thing and compare. That comparison will teach you more about what these tools can do for your business than any article, including this one.

And if the thing slowing your business down is not writing but tracking — invoices, stock, payments — that's not an AI problem. That's a software problem, and honestly, it's the kind we build.
