Keen to know this too. Maybe it is too obvious, but my customers are asking for a tax receipt and I annot find an answer on how to do this when the ordered through the ecommerce platform not POS
I would recommend having a look at our invoicing app Sufio!
Invoices created by professional print designers are sent automatically when the order is created. And of course, the invoice contains ABN, Company name and address, and Includes GST.
In case you have any questions, feel free to reach out to me at firstname.lastname@example.org. I will be happy to assist!
