A person reads these. We are a small team in Sydney, so allow a day or so.

Writing about an invoice? Tell us its number and which business it's under. Please don't send us bank details or passwords — we will never ask for them.

Common things

Before you write in.

The app was called AUS Invoice

Same app, same account, same data. We shortened the name in September 2026. Nothing was reset and there is nothing to do.

My ABN won't validate

The check runs on your device using the ATO's published checksum, so it works offline and never phones anyone. If a real ABN is refused, count the digits — eleven, no spaces needed — and send it to us if it still won't take.

My BAS figures look wrong

G1, 1A and 1B are built from invoices dated inside the quarter and expenses you've logged as having GST. A missing receipt is the usual culprit. The app gives you the numbers; it does not lodge anything and it is not tax advice.

I paid but I'm still on one business

Purchases restore themselves when you sign back in on the same Apple or Google account you bought with. If it's still wrong an hour later, tell us the email you bought with.

I want my data out

Settings has a CSV export for your accountant and a full backup file you can keep. Both come out before you delete anything.

I want my account deleted

Settings → Delete Account does it from inside the app, permanently. The steps and exactly what goes are on the account deletion page.
