Work Order Invoice Template for New Zealand

When you complete work based on a work order in New Zealand, you need a properly structured Work Order Invoice to ensure legal compliance and prompt payment. This document bridges the gap between your completed services and payment collection, while meeting New Zealand's strict commercial and tax documentation requirements.

When do you need this document?

You'll require a Work Order Invoice whenever you've completed services or delivered goods based on a previously issued work order. This includes maintenance contractors finishing scheduled repairs, IT service providers completing system upgrades, construction workers finishing project phases, or consultants delivering agreed services. The invoice references your original work order while documenting exactly what was accomplished, ensuring clear accountability between you and your client. Professional service providers, tradspeople, and contractors across New Zealand rely on this document to maintain proper business records and secure timely payments for completed work.

Key legal considerations

Your Work Order Invoice must include specific mandatory elements to satisfy New Zealand's legal requirements. The invoice header requires your company details, unique invoice number, issue date, and GST registration number if applicable. You must clearly reference the original work order number and date to establish the contractual basis for your charges. Service descriptions need sufficient detail to justify your fees, while quantity and rate breakdowns must be transparent and accurate. Under the Fair Trading Act 1986, all service descriptions and charges must be truthful and not misleading. The subtotal, GST calculation, and total amount must be clearly separated, with GST calculated at the current rate. Payment terms should specify due dates and acceptable payment methods to avoid disputes.

Legal requirements in New Zealand

New Zealand's Goods and Services Tax Act 1985 mandates that GST-registered businesses include specific information on tax invoices exceeding $50. Your invoice must display your GST number, the GST amount charged, and clearly indicate which supplies are subject to GST. The Contract and Commercial Law Act 2017 requires that your invoice accurately reflects the agreed services and pricing from your original work order. Under the Tax Administration Act 1994, you must maintain these invoices as business records for seven years. The Companies Act 1993 may require additional disclosure if you're invoicing as a company director. Financial Transactions Reporting Act 1996 provisions apply to payment terms and record-keeping for larger transactions. Ensure your invoice clearly identifies all parties, includes complete contact details, and provides sufficient detail for the client's accounts department to process payment efficiently.
