Retail Invoice Template - New Zealand

If you're GST-registered, you must include GST on all retail invoices. Businesses with annual turnover under NZ$60,000 don't need to register, but many choose to for credibility and business purposes. When registered, GST is calculated as 15% of the pre-tax amount—for example, a $100 item becomes $115 including GST. Ensure your invoice clearly shows the GST amount as a separate line item, not buried in the total. This transparency is required by Inland Revenue and supports audit compliance.

A receipt is a simple proof of purchase, while an invoice is a formal record required for GST-registered businesses. For retail, you can issue a receipt at point of sale, but if the customer requests an invoice or if you're GST-registered, provide a proper invoice with number, date, itemized details, GST breakdown, and your business information. Some retailers issue both—a receipt immediately, and an invoice for larger purchases or business customers. Check your GST registration status to confirm which document is required for your situation.

Every NZ invoice must include your business name and address, invoice number and date, customer name and address (if available), itemized description with quantity and price, total amount, and—if GST-registered—GST shown separately. For online retailers or pop-up stores, list "as provided by customer" if address is unavailable. Item descriptions should be clear enough for accurate record-keeping and dispute resolution. These details help with IRD compliance and provide evidence if issues arise. Keep copies for at least seven years as required by law.

Create a separate credit note or refund invoice rather than altering the original invoice, which maintains the audit trail required by the IRD. A credit note should reference the original invoice number, list returned items with quantities, show the refund amount, and include GST adjustment if applicable. For example, if a customer returns a $115 item (including $15 GST), your credit note reduces their balance by that amount. This method protects you during tax audits and prevents confusion when returns occur months later.

Retail invoices typically don't require payment terms since most transactions involve immediate payment via cash, card, or online. However, if you offer business customers or corporate accounts credit—such as net 30 days—you must clearly state this on the invoice with an explicit due date. Include any late payment penalties if applicable. For standard over-the-counter retail sales, payment terms can be omitted. B2B operations or wholesale arrangements selling to other retailers should always include clear payment terms to manage cash flow and prevent disputes.

Digital invoices (email, PDF) are increasingly standard and reduce storage costs, while NZ law accepts both formats. Printed invoices work well for in-store sales or specialty retail shops. For digital delivery, use secure email and maintain delivery records. Digital also enables faster customer access, reduces paper waste, and integrates with accounting software. Online retailers should prioritize digital invoices. A hybrid approach—print at point of sale for immediate proof, then email a formal invoice—works well for boutiques and small stores. Ensure your method supports seven-year record retention.

Yes, but each location should maintain a separate invoice number sequence to ensure clear record-keeping. Your main business details (IRD number) remain the same, but include the specific location address where the transaction occurred. This is important for multi-site retailers and franchises, as it tracks which store generated revenue and assists with inventory reconciliation. Consider distinct numbering—such as LOC001-001, LOC002-001—to prevent duplicate invoice numbers across locations. Duplicate numbers can trigger IRD compliance issues during audits or tax reviews.

Common errors include miscalculating GST (applying it twice or using incorrect percentages), omitting your IRD number when registered, failing to itemize goods individually, and missing dates or invoice numbers. Many retailers also overlook requirements when offering discounts—the invoice must show the final amount after discount, not an inflated original figure. Another frequent mistake is changing invoice number sequences or reusing numbers for corrections; always use credit notes instead. Additional errors involve poor backup copies or inadequate record retention, which can trigger IRD inquiries or penalties.
