Frequently Asked Questions
GST is calculated at 15% on the total value of construction work and materials. If you're GST-registered, add 15% to your subtotal—for example, $10,000 in work plus $1,500 GST equals $11,500 total. Your GST registration number must appear on every invoice. Clients who are also GST-registered can claim the GST as a credit, so accuracy is essential. Ensure your invoice clearly separates the subtotal, GST amount, and final total.
Your invoice must include your business name and address, GST registration number, invoice number and date, client's name and address, detailed description of work performed with quantities and rates, subtotal, GST amount, and total due. Add a clear payment due date and reference the client's purchase order number if provided. These elements ensure compliance with NZ invoicing requirements and help clients reconcile the invoice with their records and project scope.
Separating materials and labor as distinct line items is common and helps clients understand cost breakdown, though combining them by trade or stage is equally acceptable. Separation is especially useful for larger projects where clients may scrutinize specific costs. Match your invoice format to the original quote for consistency. Either approach works provided each line shows clear descriptions, quantities, rates, and correct GST calculations.
Issue separate invoices for each construction phase—foundation, framing, roofing, finishing—aligned with your agreed payment schedule. Clearly reference the phase name, dates, and project reference on each invoice. This prevents confusion and improves cash flow over extended projects. If your contract specifies milestone-based payments, tie your invoices to those milestones. Phase-based invoicing also makes it easier for clients to track spending against their budget and project timeline.
Create a separate invoice for variations or clearly itemize them as additional line items, always referencing the variation order date and written client approval. Never include unapproved changes on invoices—confirm pricing in writing first. For minor variations, add them to the next scheduled invoice with clear notation. Reference the original contract so clients can cross-reference the approval. This prevents disputes and ensures clients understand additional costs before payment is due.
Retention is a percentage (typically 5–10%) that clients withhold from invoice payments until project completion, ensuring contractor performance and quality standards. Show the full amount on your invoice, then deduct the retention and show the net payment due. The retained amount is usually released after sign-off and warranty completion. Check your contract for retention terms, as this significantly impacts cash flow. Your invoice must clearly communicate the retention arrangement to avoid payment disputes.
Common construction payment terms in New Zealand are Net 30 (payment within 30 days) or Net 7 for smaller jobs. State your terms clearly on every invoice—for example, "Due by [specific date]" or "Terms: Net 30 from invoice date." Align terms with your contract and align them with industry norms for your trade. Clearly stating payment terms protects both parties, speeds payment processing, and prevents cash flow delays or disputes.
Issue a quote (estimate) before work begins to propose scope and pricing; once approved and work starts, issue an invoice to request payment. Quotes are proposals; invoices are binding payment demands. Your invoice should reference the related quote number for easy client reconciliation. This quote-to-invoice workflow protects both parties by establishing clear scope and pricing before work begins, reducing disputes and ensuring clients understand the work they've approved.
