AI for quotes and invoices in New Zealand
Faster quotes and invoices with GST, what to check every time, and what to keep with you.
What AI does well
- Job notes into line items. "Replace a 180 litre cylinder, four hours’ labour, parts" becomes a quote a customer can read.
- GST worked out the same way every time. Subtotal, GST at 15% and total, shown clearly.
- Consistent numbering and layout. Every quote and invoice looks like it came from the same business.
- Polite reminders. A first, second and final reminder for an overdue invoice, firm without being rude.
Check these every time
AI can get a number wrong and sound sure about it. Before a quote or invoice goes out, check:
- Every price, quantity and discount
- The GST: price excluding GST × 1.15 is the price including GST, and a GST-inclusive price × 3 ÷ 23 is the GST in it
- Your GST number, if you’re registered (you must register once turnover passes NZ$60,000 in 12 months)
- The customer’s name and the job address
- How long the quote stands, the payment terms and how to accept
Our guide to writing a quote with GST has a template to copy. If you use a chat AI for numbers, Gnomon re-does GST, discounts, quantities and invoice totals in AI text before you rely on them.

How NOVA ONE does it
NOVA ONE makes quotes and invoices with GST for your business and prepares a reminder for each overdue invoice. Each one waits for your approval, and nothing goes out until you say so. A Jobs board follows every job from the first call to paid, and the weekly summary shows what was made.

It can prepare the reminder. NOVA ONE drafts a reminder for each overdue invoice and waits for your approval before anything is sent.
