AI prompts that actually work for small business

Most prompt lists are content-shaped noise: 'write a marketing plan' and other requests no model can answer well. What works is narrower than people think - and it works because of three things this guide teaches.

The three things every working prompt has

A role that carries context. "You are a bookkeeper who has seen a thousand freelance businesses" beats "act as an expert" - the role narrows the model's whole worldview to the useful slice.
The real inputs, pasted in. The actual invoice text, the real product description, your genuine numbers. A prompt without real inputs is a question asked in the dark.
The output format, specified. "Answer in a table with these exact columns" turns an essay into a tool. Half the value of a good prompt is the shape of what comes back.

Six prompts that beat a hundred generic ones

1. The brutal edit: "You are an editor who cuts fluff for a living. Cut this text by 40% without losing information. Return only the edited text: [paste]."

2. The customer-voice extractor: "Here are 10 real customer messages: [paste]. List the exact phrases they use to describe their problem, ranked by frequency. Do not paraphrase - quote."

3. The quote sanity check: "You are a cautious accountant. Here is my quote and my costs: [paste]. Tell me everything that could make this project lose money, in order of likelihood."

4. The listing rewriter: "Rewrite this product description for someone who has never heard of us. First line must state what it is and who it's for. No adjectives without evidence: [paste]."

5. The meeting prep: "I have a call with [client type] about [topic]. Give me the 5 questions they will most likely ask and one-line honest answers I can defend."

6. The weekly review: "Here is my week's log: [paste]. Tell me the one thing that produced the most value and the one thing I should stop doing. Be specific or say nothing."

A prompt is a tool the way a spreadsheet is a tool: the value is not in having one, but in the one that fits the exact job. Collect the ones that work for YOUR errands, keep them where you can find them, and edit them when the job changes.

What prompts cannot do

They cannot know your customers, your numbers, or your reputation. Every prompt above only works because you paste in what only you have. The model is the engine; the business knowledge is yours - that division of labor is the whole game.
