What to Include on a Plumber Invoice
A plumber invoice should cover these fields, plus a few billing norms specific to how plumbers typically operate in Australia.
Fields to include
- ABN: Your Australian Business Number must appear on every tax invoice — leaving it off risks 47% no-ABN withholding on the payment.
- GST treatment: Show the GST amount separately, or state that the total price includes GST if it is exactly 1/11 of the price.
- Invoice number: A unique, sequential number for every invoice you issue makes reconciliation and BAS preparation far easier.
- Payment details: Include a due date and your BSB/account number (or payment link) so clients can pay without asking.
How Plumbers typically bill
- A call-out fee is charged separately from labour, with an after-hours surcharge for emergency jobs.
- Small jobs are usually billed as a fixed price; larger installs (bathroom re-plumbs) are quoted and invoiced in stages.
- Insurance work is invoiced with the claim reference number and insurer details included.
- Compliance certificates for regulated work are billed as their own line item, separate from labour.
Licensed plumbers must show their state licence number on invoices, register for GST at $75,000 turnover, and lodge a Taxable Payments Annual Report for payments made to subcontractors.
Common Mistakes to Avoid
Watch out for these common errors when preparing a plumber invoice:
- Leaving off the ABN, which can trigger 47% no-ABN withholding on the payment.
- Mixing GST-inclusive and GST-exclusive prices on one invoice without labelling which is which.
- Reusing invoice numbers, which makes it harder to reconcile payments and complicates your next BAS.
Frequently asked questions
Do plumbers need to include a licence number on invoices?
Yes. In most states and territories, licensed plumbers must display their licence number on all invoices, quotes, and advertising. Check your state regulator for specific requirements.
How should a plumber invoice for emergency call-outs?
List the call-out fee, after-hours surcharge (if applicable), labour, and materials as separate line items. Include the date, time of arrival, and a description of the fault and repair.
What warranty obligations apply to plumbing work?
Statutory warranties under Australian Consumer Law apply. In most states, plumbing work carries a minimum warranty of 6 years for major defects. Specify your warranty terms on quotes and invoices.
Do I need an ABN on my invoice?
Yes. If you have an ABN, it must appear on every tax invoice. Without an ABN, the payer may withhold 47% of the payment.
When is a tax invoice required?
A GST-registered business must issue a tax invoice for any sale over $82.50 (including GST) when the buyer requests one.
What if my invoice is for less than $1,000?
Sales under $1,000 need seven details: the words "tax invoice", your identity, your ABN, the issue date, a description of what was sold, the GST amount (or a statement that the price includes GST), and which items are taxable. Sales of $1,000 or more must also show the buyer's identity or ABN.
