What's checked

Five things make it a tax invoice.

Miss one and it is just an invoice — and the business you sent it to cannot claim the GST credit. Bilby will not issue a document that is missing any of them.

Per the ATO's tax invoices guidance. Sales of $1,000 and over must also carry the buyer's identity or ABN, and itemise GST per line.

The words “Tax invoice”

On every document. Not “Invoice”, not “Statement”, not “Receipt”.
Your identity and ABN

Carried from your business details, grouped 33 401 878 017 the way the ABR prints it.
The date it was issued

Set when you issue it — never carried forward from the file you copied.
What you sold, its price, and how much of it

A description, a price and — where it applies — a quantity on every line, not one lump sum.
The GST, shown separately

Bilby itemises GST per line and marks GST-free where it applies — a government fee, an export. Under $1,000 the ATO also accepts a “Total price includes GST” statement; Bilby is stricter on purpose.

Why not a template

A template has no memory.

Duplicate last month's file and the copy carries last month's date, last month's number and last month's client. Nothing objects. Errors of this class surface at reconciliation or at BAS time — by which point the wrong document is already the one of record.

A number you cannot reuse

Numbering stays yours to choose. A number this business has already used is refused outright, and the last one — INV-2026-0184 — sits beside the field while you type.

Clients you saved once

The ABN, the postal address and the attention line come off the client record — not off your fingers at eleven at night.

Issued means frozen

Once issued, the document stops changing. What your client received is what you can still read back a year later.

Your next invoice can be the correct one.
