AI for coffee shop owners: a practical, safe start

Most AI advice for cafes is about Instagram captions. The bigger win is the back office: numbers, email, bills, schedules and reviews. Here's a practical start using the assistant you may already pay for.

Start with rules, not prompts

Give your assistant a short rulebook it reads every time: your cafe's name, your voice, your targets, and what it may never do. In ChatGPT or Claude, put it in a Project. In Gemini, put it in a Gem.

Four jobs worth handing over first

• Daily numbers. Paste yesterday's POS report and get sales, labor %, discounts % and average ticket with anything off target flagged.
• Inbox sorting. Sort vendor, catering and staff emails into Needs me, Today, This week and Ignore, with drafts for you to send.
• Price creep. Compare two invoices from the same vendor to catch increases.
• Review replies. Draft calm, specific replies in your voice. You post them yourself.

Safety rules that matter

• Draft only. Nothing sends, pays or orders without you.
• Never paste passwords, card numbers or bank account numbers.
• Connect email only through the assistant's official connector, and turn it off anytime.
• It's not your accountant. Use it to organize numbers, not to make tax calls.

Where people get stuck

Most owners try a few prompts, get busy, and stop. What works is turning prompts into routines: the same job, at the same time, handing you the same short result.
