As of 13 August 2026, AI can create an invoice for your UK freelance work.

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 invoice template and gather your trading name, address, contact details, company number if applicable and VAT registration status.
   2. Copy the client's legal or trading name, billing address and any purchase order or billing reference from the agreed work instructions.
   3. Gather the signed agreement, quote, timesheet or message confirming the services, dates, quantities, rates, expenses, currency and payment terms.
   4. Paste the gathered information into the prompt and replace every bracketed slot before asking the chatbot to create the invoice.
   5. Compare each invoice line, rate, date, subtotal and total with your agreement or timesheet, and recalculate the totals independently.
   6. Check the seller and client details, invoice number, due date, VAT treatment and payment details against your records and current GOV.UK guidance.
   7. Paste the checked invoice into your document or invoicing system, export it as a PDF, name it with the invoice number and send it to the client using the agreed contact method.
