Start free

Free for 5 invoices a month. Pro from $12 a month.

Set for New Zealand

Made for how New Zealand invoices.

GST

GST is 15% on almost everything. Exports are zero-rated.

GST no.

The GST number is your IRD number: eight or nine digits. With it saved, your invoices are titled “Tax Invoice”. Without it they are a plain “Invoice”.

NZD and local dates

Amounts are in New Zealand dollars, and you can pick another currency on any invoice. A bank statement you upload is read the way banks in New Zealand write dates.

Financial year from 1 April

Invoice numbers start a new series each April, so the first invoice of the year is OG/26-27/0001.

What a Tax Invoice needs to show in New Zealand.

Inland Revenue calls it taxable supply information:

  1. Your name or trade name and your GST number
  2. The date of the invoice
  3. A description of the goods or services
  4. The total amount, and the GST or a statement that the amount includes GST
  5. Your customer’s name and address or another identifier on sales over NZ$1,000

Check with your accountant for your case.

FAQ

Questions from New Zealand.

Does Openn Invoice make a proper Tax Invoice for New Zealand?

Yes. Add your GST no. in settings and each invoice is titled “Tax Invoice”, with GST worked out line by line at the rate you pick (15% and 0%) and totals in New Zealand dollars. What it has to show in New Zealand 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 GST no. 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 passes NZ$60,000 in 12 months.

Can I bill customers outside New Zealand?

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.
