In NZ, Invoices from a GST-registered business must show the business's GST registration number. Ideally, it should be shown like this "GST Number 123-456-789". Currently, in MYOB Business it shows like this "123456789". I have taken your suggestion of posting this on the MYOB Product Ideas Page here. Regards Alun Re: GST number of invoices I fully agree with AliHug. Having a 9-digit number under the business address is inadequate. It needs to have the words "GST Number" in front of it, and preferably formatted with a dash "-" between each group of 3 digits.
