Always

These fields prevent 80% of “we never got it” and “finance can’t pay this” loops.

  • Your legal/trading name and contact email
  • Client name and billing address
  • Unique invoice number and issue date
  • Description of work + line amounts
  • Currency, total, and due date
  • Payment method: bank details and/or pay link

By market

UK/NI often need sort code + account number and UK VAT treatment when registered. ROI commonly needs IBAN/BIC and Irish VAT when registered. If you are not VAT-registered, say so simply rather than inventing a number.

Optional but strong

Payment terms in days, PO number, and a one-line late-payment reference appropriate to the contract’s jurisdiction. Keep templates boring — boring gets paid.

Next step

Tools first, lectures second. Numbers beat awkward follow-ups.

Use invoice templates
