Tradesman Invoice Template for New Zealand

A tradesman invoice is a critical business document that formalizes your payment request after completing work for clients in New Zealand. This document serves as both a billing statement and legal record that must comply with various New Zealand laws governing business transactions and taxation. Whether you're a plumber, electrician, builder, or any other trades professional, having a properly structured invoice protects your business interests and ensures you get paid promptly.

When do you need this document?

You need a tradesman invoice every time you complete work and want to request payment from your client. This applies whether you've installed a new kitchen, repaired plumbing, completed electrical work, or provided any other trade services. The invoice is essential for both one-off jobs and ongoing maintenance contracts. You'll also need this document when working for property managers, body corporates, building companies, or private homeowners. If you're GST-registered, the invoice becomes a tax invoice that your client can use to claim GST credits, making proper formatting legally required.

Key legal considerations

Your tradesman invoice must include specific mandatory information to comply with New Zealand law. Under the Goods and Services Tax Act 1985, GST-registered businesses must include their GST number, the GST amount charged, and clearly separate GST from the base price. The Fair Trading Act 1986 requires that all services and costs are accurately represented without misleading information. You must provide clear descriptions of work performed, including dates and locations. The Consumer Guarantees Act 1993 applies to your services, so your invoice should reflect work carried out with reasonable care and skill. For construction-related work, the Construction Contracts Act 2002 may apply, requiring specific payment claim formatting and timeframes.

Legal requirements in New Zealand

New Zealand law mandates several specific requirements for trade invoices. If you're GST-registered with annual turnover exceeding $60,000, your invoice must function as a tax invoice containing your GST number, invoice date, supply details, and GST calculations. The invoice must clearly identify both your business and the client, including full contact details and addresses. Under the Contract and Commercial Law Act 2017, your payment terms must be clearly stated, including due dates and any penalty interest rates. For construction work over $30,000, you may need to comply with Construction Contracts Act requirements for payment claims. Keep detailed records as the Inland Revenue Department requires businesses to maintain invoice records for seven years. Your invoice should also reference any relevant warranty periods or guarantee terms that apply under the Consumer Guarantees Act.
