What to put on a plumber invoice

  • Your business name, contact details and business number (for example your ABN in Australia)
  • Your customer's name and the job address
  • An invoice number that goes up each time, the date, and when payment is due
  • Each item of work or materials, with quantity, price and amount
  • The tax amount, if you're registered for GST or VAT
  • How to pay you, and the reference to use

If you're registered for GST or VAT, your country may require extra details on a tax invoice (in Australia, for example, the words "Tax invoice", your ABN and the GST amount). Check with your accountant.
