Quote with GST calculated properly and your ABN in the right place — then convert it into a valid tax invoice the moment the client says yes. Built for sole traders, tradies and small businesses billing in AUD.
Free · GST and ABN handled · Converts to an ATO-compliant tax invoice
Include it on the quote. It signals you're a legitimate registered business and carries across to the tax invoice.
If you're registered, show the 10% GST. If you're not, don't charge it — and say the price includes no GST so there's no confusion.
Labour, materials and callout separated out. Itemised quotes get accepted; lump sums get negotiated.
"Valid for 30 days" protects you from material price movement and prompts a decision.
State the deposit and payment window up front — agreed before the job, not chased after it.
What's not included: rubbish removal, permits, making good. This is where most AU trade disputes start.
Entered once and remembered. Your ABN appears on both the quote and the invoice it becomes.
Registered for GST? Switch it on and 10% is calculated for you. Under the $75,000 threshold? Leave it off and the quote is labelled correctly.
Add line items, validity period, deposit and exclusions. Totals calculate themselves.
Email the quote. When accepted, convert it to a tax invoice that meets ATO requirements.
Convert your quote into an ATO-compliant tax invoice with GST and ABN already in place.
Create an invoiceIf you're registered for GST you must show it, and it's best practice to state whether your prices include or exclude GST — ambiguity here is a common source of disputes. If you're not registered, don't charge GST, and say the price includes none.
You can quote without one, but you should get an ABN if you're operating a business. Without it, business clients may be required to withhold 47% of the payment. An ABN is free from the Australian Business Register.
A quote is generally an offer at a fixed price, and once the client accepts it you're usually bound to that price. That's why validity dates and clear exclusions matter — and why you should give an estimate instead when the scope isn't settled.
A quote is what a job will cost, sent before the work. A tax invoice is the request for payment after it, and for sales over A$82.50 including GST it must carry specific details — the words "Tax invoice", your identity and ABN, the date, a description, and the GST amount.
Convert it in InvoiceSonic. The client, line items, GST and your ABN all carry across into a numbered, ATO-compliant tax invoice you can send straight away.
