What is a GST-compliant tax invoice?
In Australia, a tax invoice must include your ABN, the words "Tax Invoice", the date, a description of goods or services, the total price, and the GST amount shown separately. The ATO requires these for any transaction over $82.50 (inc. GST). SMASH generates every one of these fields automatically — from your voice description alone.
Calculating 10% in your head — then second-guessing it
Forgetting to include your ABN and having to resend
Not knowing if your invoice meets ATO requirements
Clients rejecting invoices for missing details
Spending Sundays fixing invoices before BAS time
Every SMASH invoice includes
Your ABN — pre-filled from your account
"Tax Invoice" heading — required by ATO
Date of issue — auto-generated
Itemised description from your voice
GST calculated at 10% per line item
Total GST amount broken out separately

"My accountant said all my invoices were perfectly formatted for BAS. I just told her I got a better app. She's been recommending it to her other clients."

"I used to redo invoices every BAS time because I'd forgotten the ABN or the GST line. Never happened once since I switched to SMASH."

"GST calculating itself is worth the price of the app alone. I didn't even realise I was getting it wrong on some invoices until SMASH started doing it for me."
