Subcontractor Invoice Template for New Zealand

When you work as a subcontractor in New Zealand, you need a professional invoicing system that meets legal requirements while ensuring you get paid promptly. A subcontractor invoice serves as your formal request for payment and creates a legal record of the services you've provided to main contractors or clients.

When do you need this document?

You'll need a subcontractor invoice whenever you complete work for another business or reach agreed billing milestones. This applies whether you're providing specialized trades services on a construction site, offering professional consulting to a larger firm, or delivering any contracted services as an independent contractor. The invoice becomes particularly important when working with multiple parties on complex projects, as it clearly establishes your role, the work completed, and the payment obligations. You should issue invoices promptly after completing work or according to the payment schedule outlined in your subcontractor agreement to maintain positive cash flow and professional relationships.

Key legal considerations

Your subcontractor invoice must include specific information to comply with New Zealand law and protect your payment rights. If you're GST-registered, you must include your GST number and charge the appropriate GST rate on your services. The invoice should clearly identify all parties involved, describe the services provided in detail, and specify payment terms including due dates. You need to maintain proper records of all invoices for tax purposes, and ensure your invoicing practices align with any master service agreements or subcontractor contracts you've signed. Consider including retention clauses if applicable to your industry, and be aware that construction-related invoices may have additional statutory requirements under the Construction Contracts Act.

Legal requirements in New Zealand

Under the Goods and Services Tax Act 1985, GST-registered subcontractors must include their GST number on invoices and charge GST at the current rate. The Tax Administration Act 1994 requires you to maintain accurate records of all business transactions, including invoices, for at least seven years. If you're working on construction projects, the Construction Contracts Act 2002 provides specific protections around payment timing and dispute resolution that may affect your invoicing process. Your invoices must also comply with the Fair Trading Act 1986, ensuring all information is accurate and not misleading. Additionally, the Contract and Commercial Law Act 2017 governs the broader commercial relationship, so your invoice terms should align with your underlying service agreements to avoid payment disputes.
