Simple Invoice Template - New Zealand

If your annual turnover is under NZD $60,000 (or NZD $24,000 for charities), GST registration is optional—you can choose to register voluntarily anyway. If you're not registered, don't list GST separately on your invoice; your quoted price is the final amount. Once you register for GST, you must show it as a separate line on every invoice and remit it to the IRD quarterly. A simple invoice template should clearly indicate whether GST is included or excluded, making this distinction obvious to both you and your clients.

A valid NZ invoice must include: your business name and contact details, a unique invoice number, the invoice date, the client's name and address, a clear description of goods or services provided, the price of each item, and the payment terms or due date. If you're GST-registered, you must show the GST amount separately and your IRD number. The IRD doesn't mandate specific formatting, but these elements are legally required for a compliant invoice accepted for accounting and tax purposes.

A simple invoice works best for straightforward transactions: single items or a short list of services, small to medium invoices, and businesses where detailed line-item tracking isn't essential. If you're billing for multiple projects, need to track time across departments, or invoice clients with complex purchase orders, a detailed or specialized template is more appropriate. A simple template keeps administration fast and reduces errors for freelancers, service providers, and small trades working on fixed-price contracts.

Payment terms in New Zealand typically range from 7 to 30 days, with 'payment due 7 days' common for small businesses and 'net 14' or 'net 30' standard for larger transactions. Smaller businesses or contractors often specify 'payment due on receipt' for quicker cash flow. Whatever you choose, state it clearly on your simple invoice. Specifying clear terms reduces disputes and sets expectations, though you may negotiate with larger clients or those with their own payment schedules.

Yes, but with adjustments. For exports outside New Zealand, you may be able to invoice with 0% GST (zero-rated supplies), which requires you to identify the transaction as an export. A simple invoice can work, but you should include the client's country, note whether GST is applied, and clarify payment currency—typically NZD or USD. For recurring international clients, you might later upgrade to an international invoice template that handles currency conversion and country-specific tax rules, but starting simple is acceptable.

Simple invoices work well for freelancers, consultants, tradespeople, small service businesses, and sole traders. However, if your business operates complex supply chains, invoices multiple departments, requires project cost tracking, or works with repeat orders, you'll eventually need a more detailed template. Additionally, specialized service industries may have specific invoice requirements beyond the basics. Start with a simple template and upgrade as your business grows or your invoicing needs become more complex.

The IRD requires you to retain invoices and supporting documents for at least 7 years from the date you lodged your tax return for that income year. This applies whether you invoice on paper or digitally. A simple invoice template should be stored reliably—either digitally with backup copies or in organized physical files—to support your tax compliance and meet IRD audit requirements. Proper record-keeping protects both you and your clients in case of disputes or tax inquiries.

Include clear payment details: your business bank account number (and branch if needed), your account name, and any specific reference information. Specify your preferred payment method—direct bank transfer is fastest in New Zealand. Set shorter payment terms (7 days rather than 30) and state them prominently on the invoice. Send invoices immediately after completing work, not at month-end. Simple templates that highlight payment information tend to reduce delays and speed up cash flow.
