What should a sole trader invoice include?

What should a sole trader invoice include? In 2026-27, a sole trader invoice needs a unique number, your name and any business name, your address, the customer's name and address, a description, the date of the work, the invoice date, the amounts and the total. GOV.UK says an invoice is required by law when both you and the customer are VAT registered. In our reading, it is still the simplest proof of what you charged, and GOV.UK lists sales invoices among the records the self-employed keep. Yes. GOV.UK says to show your own name and the business name, plus an address where legal documents can be delivered to you. A sole trader's business name must not include 'limited', 'Ltd' or 'plc'. Only if you are VAT registered. HMRC's record-keeping notice says only VAT-registered businesses can issue VAT invoices. If you are not registered, you do not show a VAT number or charge VAT.
