AI invoice generator
Tell Siteglade, an AI agent, what you invoice and how, and it builds an invoice template as a spreadsheet with working formulas for line totals, tax and the amount due, with your logo and details. It can also deliver a filled-in invoice as a PDF.
Siteglade publishes this page about its own agent; the example prompts come from its feature pages.
What you get
Spreadsheets come with working formulas, clean formatting and charts, as Excel or CSV files.
- Your name, address, tax number and bank details in the header.
- Line items with quantity, price and line totals.
- Tax and the amount due, calculated by formulas.
- An invoice number and dates in the format you use.
- A second sheet that lists every invoice, if you want one.
How to ask for it
Four steps, from the first sentence to the finished file:
- Write what you invoice: hours, products or fixed fees.
- Add your details, your tax rate and your payment terms.
- Attach your logo and an old invoice if you have one.
- Check the formulas with one test invoice, then use the template.
Prompts to start from
Copy one and change the details to your own:
- “An invoice template for a freelance designer with hourly rates, VAT and payment terms of 14 days”
- “An invoice spreadsheet for my cleaning business with a sheet that lists every invoice and whether it was paid”
What to check before you use it
An agent saves the work, not the responsibility. Check these before the result goes out:
- The tax rate and the legal details your country requires on an invoice.
- Every formula, with a test invoice.
- That invoice numbers never repeat.
