01Why half-bot

  • Accepting card payments and tracking who paid needs real software.
  • For a few invoices a month, a template can be enough.

02The prompt

Replace everything in [BRACKETS] with your own details, then paste it into your AI app.

prompt.txt
Create an invoice template for [Google Sheets / Excel / Google Docs].

My business name and contact email: [DETAILS]
What I bill for: [e.g. hourly design work, fixed-price projects]
Payment terms: [e.g. due in 14 days]

Include: invoice number, dates, client block, line items (description, quantity, rate, amount), subtotal, tax line (leave the rate as a blank cell I fill in), total, and payment instructions.
Give me the exact layout and every formula. Explain for a beginner.

03Steps

  1. Build the template once.
  2. Duplicate it for each new invoice and update the invoice number.
  3. Export to PDF to send.

04What can go wrong

  • Check your local sales tax rules. Don't let AI guess your tax rate.
