AussieInvoice verifies ABNs against the public Australian Business Register as you enter them, filling in the legal entity name, ACN and GST registration status for you to review before saving. Most invoicing tools accept whatever ABN you type without checking it, which is how the wrong legal name reaches a tax invoice.
An Australian tax invoice has to carry the supplier's identity and ABN, and for sales of $1,000 or more it also has to identify the buyer. If the ABN is mistyped, or if it belongs to a trading name rather than the legal entity, the document is wrong in a way that only surfaces later — usually when your customer's bookkeeper refuses it, or at BAS time.
The failure is quiet. A mistyped ABN looks exactly like a correct one, and nothing in a typical invoicing tool objects. You find out weeks later when payment is held up.
Checking the ABN against the Australian Business Register at entry catches it immediately, and confirms something the number alone does not tell you: whether that entity is currently registered for GST.
You enter the ABN. AussieInvoice queries the public ABR record and returns the registered legal name, the ACN where the entity is a company, and the entity's GST registration status.
Those values are presented for you to review, not silently written. You confirm they match the business you are invoicing, then save. The review step matters: the ABR is the source of truth for the registration, but only you know whether it is the right registration.
The same details then flow into the invoice, so the legal name on the document matches the register rather than whatever was typed into a contact form months ago.
Yes. GST registration status is part of the public ABR record, and it is the part most often assumed rather than checked.
This matters in both directions. If you are not registered for GST, your invoice must not be headed 'Tax invoice' and must not show a GST amount. If your customer is not registered, they cannot claim a credit for the GST you charge — which occasionally surfaces as a dispute rather than a payment.
Guided ABR lookup inside the invoice flow is uncommon. The large accounting platforms — Xero, MYOB, QuickBooks — store an ABN field on the contact record, and validate its format, but do not walk you through confirming the entity against the register as part of creating the invoice.
AussieInvoice does the lookup as a step in setting up your own business profile and your customer records, because getting the entity right once is what keeps every later invoice correct.
If you are choosing between tools on this specific point, check whether the ABN field is validated for format only, or actually resolved against the ABR. They are very different things and the interfaces look identical.
