Electrician invoice example: what a correct one looks like

The fastest way to sanity-check your own invoice is against a realistic one. Below is a filled-in example for a typical residential sparkie job (supply-and-install downlights plus a switchboard inspection) showing how the licence number, call-out fee, materials markup and GST-per-line should read.

Every figure follows ATO tax invoice rules: GST is one-eleventh of each GST-inclusive line, shown per item, with the "Tax Invoice" heading and ABN up top.

Trade-specific rules

GST notes for electricians

Electrical Services: one of the largest sole-trader trades in Australia, with most sparkies invoicing a mix of labour, materials at markup, and fixed call-out fees.

  • Include your electrical licence number near your ABN; plan managers, builders and real-estate agents will bounce invoices without it.
  • Materials you on-sell (fittings, cable, breakers) carry GST at your marked-up price, not your trade price; GST is calculated on what you charge the customer.
  • A certificate of electrical safety (or equivalent in your state) is a taxable supply like any other line, so don't leave it off the invoice as a freebie unless you mean to.

Fair questions

FAQ

Is GST added on top of my hourly rate or included?

Either works, as long as the invoice is clear. If you quote $110/hr inc GST, the GST portion is $10 (one-eleventh). If you quote $110 + GST, the line total is $121. The example shows ex-GST rates with GST added.

What if the customer is a builder claiming GST credits?

Nothing changes on your side, but a correct Tax Invoice matters more, because the builder needs it to claim the credit. Invoices of $1,000+ (inc GST) must also show the builder's identity or ABN.

Can I invoice before the certificate of safety is issued?

You can invoice when the work is done under most terms, but many electricians line the certificate up with the final invoice so the paper trail matches. Check your contract terms for staged work.
