Frequently Asked Questions
Include your GST registration number (if registered), show GST separately at 15%, and assign each invoice a unique sequential number. A compliant customer invoice template automatically handles these calculations and formatting, eliminating manual errors. Add the invoice date, payment terms, and both customer and supplier details to complete requirements. Using a template ensures consistency and reduces audit risks by maintaining proper documentation standards.
No—you can invoice customers before registering for GST. However, once your annual turnover exceeds $60,000, registration becomes compulsory within 30 days. Before registration, don't include GST on invoices. Once registered, your GST number must appear on every customer invoice with GST calculated at 15%. Many small businesses invoice without GST initially, then add it when they cross the registration threshold.
Sequential numbering is an IRD requirement for audit accountability and record-keeping. Deliberately skipping numbers raises questions during reviews and suggests missing or voided invoices. If you accidentally skip a number, document why—IRD may ask for clarification. Using a template or invoicing software that auto-increments prevents gaps and keeps records audit-ready. Consistent numbering demonstrates proper record-keeping practices.
You can issue a pro-forma invoice or deposit invoice before delivery, but this isn't your final tax invoice unless you've invoiced the full amount upfront. Once you deliver, issue a proper tax invoice the customer can use for their own record-keeping and GST claims. Timing depends on your agreement with the customer. Service businesses often invoice on completion or at agreed milestones rather than upfront.
Simply omit GST from your customer invoice—show only your net amount due. You can include 'GST not applicable' or leave the GST line off entirely; both approaches are acceptable. Noting that you're not GST registered helps manage customer expectations or answer questions about missing tax. Once you register, issue a new invoice showing GST at 15% if the customer needs it for their records.
A valid NZ customer invoice must include your business name and address, customer name and address, invoice date, unique sequential number, itemized description of goods or services, quantity and price, GST registration number (if applicable), and GST amount shown separately. If GST applies, it must appear as a distinct line item. Payment terms and due date are best practice but not legally required for basic invoice validity.
Electronic invoices are fully legal in New Zealand—there's no requirement to print them. Email, cloud storage, or invoicing software platforms are all acceptable ways to send and store customer invoices. The IRD accepts digital records as long as they're accurate, complete, and retrievable. Ensure digital copies preserve all required details and that both parties maintain reliable records. Electronic delivery saves time and costs for most NZ businesses.
If the customer hasn't seen it, simply correct and resend. If they've already received it, issue a credit note for the incorrect invoice and send a new corrected one immediately. Never cross out or rewrite details on an already-sent invoice—this breaks the audit trail. Credit notes and replacement invoices create proper documentation for IRD purposes. This approach keeps your records clear and demonstrates good record-keeping practices.
