Tradie Invoice Template Australia: What Every Invoice Needs (Free Example)

Quote vs invoice: what's the difference?

A quote is an offer — what the job will cost if the customer says yes. An invoice is the bill you send once the work's done (or as a deposit request), asking to actually be paid. They look similar, but an invoice has stricter legal requirements, especially if you're GST-registered.

What the ATO requires on a tax invoice

If you're registered for GST, any invoice over $82.50 (including GST) must be a tax invoice, and it legally needs:

1. The words "Tax Invoice" stated clearly
2. Your identity — business name and ABN
3. The date the invoice was issued
4. A brief description of the goods or services supplied
5. The GST amount payable — or a statement that the total price includes GST
6. The total amount payable

If you're invoicing a business customer for more than $1,000, you also need to include their identity or ABN.

None of this is optional if you're GST-registered — get it wrong and your customer's accountant may bounce the invoice back to you, delaying payment.

What to include beyond the legal minimum

The legal requirements are the floor, not the ceiling. A genuinely professional invoice also includes:

• Itemised line items — labour and materials broken out separately, not lumped into one number. Customers pay faster when they can see exactly what they're paying for.
• Payment terms — due date, and accepted payment methods (bank transfer, card). "Due on receipt" or "Net 7 days" is standard for trade work; avoid vague terms like "ASAP."
• Bank details — BSB and account number front and centre. Every extra click a customer has to make to pay you is a delay.
• Invoice number — sequential numbering (INV-0001, INV-0002...) makes your books far easier at tax time and looks more professional than a one-off document.
• A late payment clause — even a simple line like "A 1.5% monthly fee applies to overdue invoices" meaningfully improves on-time payment rates, even if you never actually enforce it.

The invoicing mistakes that delay payment

Sending it too late. Every day between finishing the job and sending the invoice is a day the customer's enthusiasm (and memory of why they needed you) fades. Invoice same-day or next-day, always.

No clear due date. "Please pay soon" isn't a due date. Put an actual date on it.

Making customers hunt for how to pay. If your bank details are buried in a footer, or you're asking people to call you for payment info, you're adding friction. Put them in the main body.

Never following up. Most overdue invoices aren't a customer refusing to pay — they've just forgotten. A polite reminder at 3–5 days overdue collects the large majority of late payments without any awkwardness.

From quote to invoice in one step

If you already sent a professional quote, invoicing should just be converting that same document once the job's done — not starting from scratch. SmokoHQ auto-generates tax-invoice-ready invoices with your ABN, itemisation, and GST handled automatically, and can convert an accepted quote straight into an invoice. Try it free.

The bottom line

An invoice that's clear, itemised, and easy to pay gets paid faster than one that's technically correct but a hassle to act on. Nail the ATO requirements first, then optimise for how quickly a busy customer can click "pay."
