How to pay

Bank details or pay link, and when payment is due.

Not registered for GST? Change "Tax invoice" to "Invoice" and leave the GST line out. Customer hasn't paid? Here's how to chase an unpaid invoice.

What an invoice should show in Australia

  • If you're registered for GST, call it a tax invoice. If you're not registered, don't use the words "tax invoice". ato.gov.au
  • A tax invoice under $1,000 must show that it's a tax invoice, who you are, your ABN, the date, what you sold with the quantity and price, the GST (or "Total price includes GST" when the GST is exactly one-eleventh of the total), and how much of each sale is taxable. ato.gov.au
  • For sales of $1,000 or more, it must also show the customer's name or ABN. ato.gov.au
  • If a customer asks for a tax invoice, give it within 28 days, unless the sale is $82.50 or less including GST. ato.gov.au
  • Also worth adding: a unique invoice number, your contact details, and when and how you want to be paid. business.gov.au

In New Zealand

  • Since 1 April 2023, New Zealand doesn't require a "tax invoice". You keep and give "taxable supply information" instead. business.govt.nz
  • Over $200 up to $1,000: your name or trade name and GST number, the date, a description, and either the amount before GST, the GST and the total, or the total with a statement that it includes GST, if everything is at the standard rate. ird.govt.nz
  • Over $1,000: also the buyer's name and an identifier such as their address, phone, email or NZBN, if the buyer is GST registered. ird.govt.nz
  • If a GST-registered buyer asks, give it within 28 days for sales over $200. ird.govt.nz

Tips for plumbing invoices

  • Keep the hot water unit on its own line, separate from the labour to fit it.
  • Say whether the price includes after-hours or weekend rates.

Questions about plumbing invoices

What should a plumbing invoice include?

The work you did, each on its own line, such as call-out fee, labour, finding and clearing the blockage, parts. Then "Tax invoice" if you're registered for GST, your ABN, the date, the GST and the total, and when and how you want to be paid. Source: ato.gov.au, business.gov.au.

What's worth adding to a plumbing invoice?

List the brand, model and size of a new hot water unit, so the customer has it for the warranty.

Do I need to give a plumbing compliance certificate?

In New South Wales, at the end of all plumbing and drainage work you complete a Certificate of Compliance and give a copy to whoever arranged the work. In Victoria you need one when the work is worth more than $750, including materials, labour and GST, and for some work at any value, and it goes to the customer within five days of finishing. Source: nsw.gov.au, bpc.vic.gov.au.
