Four things go on every New Zealand invoice, two more once the supply is over NZ$200, and one more over NZ$1,000 when the buyer is GST-registered. Pick the band, then work down the list against an invoice you have actually issued.

Over NZ$200, Inland Revenue asks for your GST number. That is not your NZBN. Your NZBN identifies your business; your GST number relates to GST, and the two come from different places.
General information only, current at the time of writing. It is not tax advice and does not account for your circumstances. For anything that matters, check with your accountant or Inland Revenue.
BookAndGo builds the invoice from the appointment, so your business name, the date, what was sold and its price are simply there. Your GST number, NZBN and business details come from your settings, the GST is worked out for you, and the numbering runs in sequence without you tracking it.
