Basic Invoice Template - New Zealand

A New Zealand invoice must include your business name and address, invoice number and date, client name and address, itemized list of goods/services with descriptions and amounts, total amount, and payment terms. If you're GST-registered, display your GST number and calculate GST separately on applicable items. The invoice should clearly state whether GST is included or added to the total, and provide your payment instructions (bank details or payment method). These requirements ensure compliance with New Zealand tax law and facilitate proper accounting records.

In New Zealand, you must register for GST if your annual turnover exceeds $60,000, and you can register voluntarily below that threshold. Once GST-registered, your invoices must display your GST number and show GST separately on each line item or as a total addition. GST is currently 15% on most goods and services. Your invoice must clearly indicate whether amounts are GST-inclusive or GST-exclusive, preventing confusion for your clients. GST-registered businesses can claim input tax credits on their business expenses, making accurate invoicing essential for tax compliance and maximizing deductions.

Include clear payment terms specifying when payment is due—common options are net 7, net 14, or net 30 days from invoice date, though immediate payment or deposits are also acceptable for certain industries. Provide multiple payment methods to accommodate clients: bank transfer (including your bank account details), credit card, payment apps like Stripe or PayPal, or cheque. Banking details should show your account name, account number, and bank branch. Clear payment instructions reduce late payments and queries. Consider offering early payment discounts if cash flow permits, and specify your late payment policy to set client expectations from the start.

Start with a professional basic template and modify the service descriptions to match your industry. Digital services, consulting, contracting, and creative work all benefit from tailored line-item details: freelancers might add hourly rates and hours worked, contractors might list project milestones, and service providers might specify time periods. Keep your business branding consistent, update your GST number if applicable, and ensure payment instructions match your preferred methods. The template structure remains the same, so you're only customizing descriptions, pricing, and branding while maintaining a professional appearance that reflects your business type.

Yes, invoices are generally required for business transactions, though informal cash transactions under $100 may have different requirements depending on your business type. GST-registered businesses must issue tax invoices showing the GST number for all sales; non-registered businesses can issue simpler invoices without GST details. If you're self-employed or operating as a contractor, invoices document your income for tax purposes and protect both you and your client. Even if payment has already been received, a formal invoice creates a paper trail for accounting records, tax filings, and dispute resolution. Consistent invoicing demonstrates professionalism and meets IRD expectations.

For recurring services like monthly website maintenance or retainer agreements, issue a fresh invoice at each billing cycle with an updated invoice number, date, and the service period clearly stated. Specify the recurring period (e.g., 'Month 1 of 6' or 'March 2025 Monthly Services') to avoid confusion about what period the invoice covers. Include the same payment terms and GST calculations as one-off invoices. Some businesses include the next due date or payment schedule at the top to help clients plan. Consistent, timely invoicing for recurring services builds client trust and ensures predictable cash flow while maintaining clear financial records for both parties.

A pro forma invoice is a preliminary estimate showing what you'll charge before work is delivered—it's not a formal demand for payment and doesn't affect GST reporting. A standard invoice is issued after work is completed and serves as the official request for payment, triggering your revenue recognition and GST obligations. Pro forma invoices help clients budget and approve costs beforehand. In New Zealand, only standard invoices appear in formal accounting records and GST returns. Use pro forma invoices for large projects or new clients to confirm pricing, then issue a standard invoice once the work is done. Both should include your GST number if registered.

Keep copies of every invoice you issue—digital storage is acceptable under New Zealand tax law. Retain invoices for at least 7 years, as the IRD may request them during audits or disputes. Store associated documentation: payment receipts, delivery confirmations, email communications, and supporting timesheets or project details. If you're GST-registered, your invoices form the basis of your GST return, so accurate records are essential. Organize invoices by date or invoice number for easy retrieval. Cloud-based accounting systems automatically archive invoices and generate reports. Proper record-keeping demonstrates compliance, supports tax deductions, protects against disputes, and simplifies annual tax filing or financial audits.
