FAQ

Questions from Australia.

Does Openn Invoice make a proper Tax Invoice for Australia?

Yes. Add your ABN in settings and each invoice is titled “Tax Invoice”, with GST worked out line by line at the rate you pick (10% and 0%) and totals in Australian dollars. What it has to show in Australia is listed on this page. Check with your accountant for your case.

Does it file my GST return?

No. Openn Invoice makes invoices and shows who has paid. It does not file returns or keep full accounts. Paid plans include a tax report and CSV downloads to hand to your accountant.

I am not registered for GST. Can I still use it?

Yes. Leave the ABN empty in settings and send invoices with no GST on them. They are titled “Invoice” instead of “Tax Invoice”. GST registration is required once turnover reaches A$75,000 a year.

Can I bill customers outside Australia?

Yes. Pick the customer’s country and currency on the invoice. A customer abroad is billed as an export, with no GST added. You see the reason on the invoice before you send it.

What does it cost in Australia?

Free covers 5 invoices a month. Pro is $12 a month or $99 a year, with unlimited invoices, recurring invoices and bank statement matching. Prices exclude GST.
