As of 13 August 2026, AI can create a business invoice.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, no skill needed, and roughly 15 minutes until you can act on the result.

   How to actually do it

   1. Open a blank document or spreadsheet and gather your business details, customer billing details, invoice number, invoice date, supply date, payment terms and payment information.
   2. Copy the line items from your quotation, order record or contract, including descriptions, quantities, unit prices, discounts and any agreed VAT rates.
   3. Paste the information into the prompt, stating clearly whether the business is VAT registered and leaving unknown fields marked as missing rather than guessing.
   4. Ask the chatbot to produce the calculation table and formatted invoice using the prompt exactly as written.
   5. Compare every description, quantity, price, subtotal, VAT amount, total, date, invoice number and payment detail against your order records and accounting records.
   6. Check the invoice format and VAT wording against current GOV.UK guidance, or ask an accountant to check it if the transaction or VAT treatment is unusual.
   7. Paste the verified invoice into your document or invoicing system, export it as a PDF if appropriate, and send it to the customer using the agreed contact details.

   Calculate the line totals, subtotal, discounts, VAT and grand total only from the supplied figures. Show the calculation in a simple table, then provide a clean invoice that can be pasted into a document. Mark every figure or field that needs my confirmation. Use plain UK English. Do not describe the invoice as legally compliant unless the supplied information and current official guidance support that conclusion.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
