Who it’s for

Business owners, freelancers, bookkeepers and anyone tracking money.

Adapt it to your industry

  • Restaurant: weekly food-cost summary from invoices
  • Freelancer: sort expenses for tax time
  • Agency: monthly profit per client in one sheet

Step by step

  1. Export the data you have (bank CSV, invoices, sales report) without account numbers.
  2. Open ChatGPT, Claude or Grok, upload or paste it, and paste the prompt below.
  3. Ask for categories, totals and a short summary of anything unusual.
  4. Spot-check 5 lines by hand; correct the AI where it is wrong.
  5. Ask for a Google Sheets template with formulas so you can repeat it monthly.
  6. Have an accountant check anything that affects taxes.
