A proper tradie invoice needs your business and contact details, your ABN, the customer’s details, a clear description of the work, an itemised breakdown of costs, the GST, the total, and clear payment details and terms. Getting these right makes you look professional, keeps you square with the tax office, and — done well — gets you paid faster.
The must-haves
Every invoice should carry your business name and contact details, your ABN, the word “Invoice,” a unique invoice number, the date, and the customer’s name and details. If you’re registered for GST, the invoice needs to show the GST component and be a valid tax invoice. These aren’t optional niceties — they’re what makes the document legitimate.
The description that prevents disputes
Describe the work clearly and itemise it. “Labour and materials — $2,400” invites questions. “Supply and install Rheem 250L hot water system, 2 hours labour, PTR valve and anode kit” leaves no room for confusion and heads off disputes before they start. Clarity gets you paid; vagueness gets you queried.
The payment details that speed things up
Make it obvious how and when to pay. Include your payment terms (when it’s due), your bank details, and ideally a way to pay online in one tap. The easier you make paying, the faster it happens. Burying your BSB at the bottom in small print is a delay you’re choosing.
The extras that mark you as professional
A due date stated plainly, a reference for the customer to use, and a polite thank-you all add up to an invoice that reads like it came from a business that has its act together — which makes customers more comfortable paying promptly.
Stop building invoices from scratch
Every one of these details is the same on every invoice except the job specifics — which is why building invoices by hand is wasted time. TradieO builds compliant, itemised invoices from your voice on site, with your details, ABN, GST, terms, and a pay-now button already in place. You describe the job; the invoice is done.
Frequently asked questions
Do I need an ABN on my invoice?
Yes — if you’re running a business, your ABN should be on your invoices. Without it, customers may be required to withhold tax from the payment.
When does an invoice need to be a “tax invoice”?
If you’re registered for GST, you issue tax invoices that show the GST. If you’re not registered, you don’t charge GST and issue a regular invoice.
What payment terms should I use?
Common terms are net 7, 14, or 30 days. Shorter terms get you paid sooner — many tradies use net 7 or 14.
