What Is an Invoice?
An invoice is a commercial document issued by a supplier to a buyer recording the details of goods or services supplied and demanding payment. In New Zealand, invoices serve two purposes: they are the contractual demand for payment under ordinary commercial law, and they are tax invoices for GST-registered businesses under the Goods and Services Tax Act 1985.
From 1 April 2023, the Taxation (Annual Rates for 2022–23, Platform Economy, and Remedial Matters) Act 2023 introduced the concept of "taxable supply information" (TSI), replacing the old tax invoice rules. The new rules require GST-registered suppliers to provide buyers with prescribed information at prescribed times, with more flexibility about how the information is supplied. Doxuno’s invoice template captures all the required fields.
A professional invoice clearly identifies the supplier (including NZBN and GST number), the buyer, a unique invoice number, the date, a clear description of what is being supplied, the amount (with GST separately identified), and the payment terms. It is the foundation of accounts receivable, and clear, consistent invoicing is one of the strongest predictors of healthy cashflow.

Legal Considerations
New Zealand invoicing is governed by the Goods and Services Tax Act 1985 and supported by general contract law.
This template is for informational purposes only and does not constitute tax or legal advice. For complex GST situations (imported services, mixed supplies, reverse charge), consult a chartered accountant or tax adviser.
GST-compliant under NZ tax law
Taxable Supply Information (from 1 April 2023)
Under sections 19E and 19F of the Goods and Services Tax Act 1985, GST-registered suppliers must provide taxable supply information to GST-registered recipients for supplies over $200. For supplies over $1,000, additional information is required including recipient details. Records must be kept for seven years. These rules replace the old "tax invoice" terminology but the substance of the requirement is very similar.
Fair Trading Act 1986
Sections 9 and 13 of the Fair Trading Act 1986 prohibit misleading and deceptive conduct and false representations in trade. Invoices that misdescribe goods, overstate quantities, or charge for services not supplied can breach these provisions and expose the supplier to Commerce Commission action under section 40 and civil remedies under section 43.
Interest on Overdue Amounts
Contract-based interest on overdue invoices is enforceable provided it is clearly stated in the supply terms or invoice and the rate is not penal. The Credit Contracts and Consumer Finance Act 2003 applies where the supply is to a consumer and unpaid amounts constitute a credit contract — disclosure and rate limitations may apply. For business-to-business supplies, reasonable interest rates are generally enforceable.
Debt Recovery
Unpaid invoices can be recovered through the Disputes Tribunal (up to $30,000), the District Court (up to $350,000), or the High Court for higher-value claims. The Construction Contracts Act 2002 provides specific adjudication processes for construction-related invoices. Issuing a formal statutory demand under the Companies Act 1993 section 289 is a common step for corporate debtors.
