Frequently Asked Questions
No, GST registration isn't required to invoice clients. However, if your annual turnover exceeds $60,000, you must register with the IRD. If registered, you'll include your GST number on invoices and charge GST on taxable supplies. Many sole proprietors choose to register voluntarily for credibility, even below the threshold. Either way, your invoice remains legally valid. The key is ensuring your invoices comply with IRD requirements, regardless of GST status.
A valid NZ invoice requires your business name, address, invoice number, date, client name and address, detailed description of work provided, quantity and rate, total amount due, and payment terms. If GST-registered, include your IRD number and GST amount clearly. Many sole proprietors also add phone number and email for client convenience. These elements ensure your invoice meets IRD requirements and can be used as supporting documentation for tax purposes.
The main difference is that sole proprietors don't include a company registration number on invoices, whereas companies must. As a sole proprietor, you invoice in your own name rather than a corporate entity. Both must follow the same mandatory invoice elements and GST requirements if registered. Sole proprietor invoices are simpler administratively—no board approvals needed. The liability structure differs legally, but invoicing requirements remain similar. Your invoice maintains credibility and compliance either way.
Yes, sole proprietors regularly invoice overseas clients. For GST purposes, if your client is outside New Zealand, the supply is generally zero-rated (GST-free), so you won't charge GST even if registered. Include your IRD number and clearly state the GST treatment on the invoice. Consider the client's currency preferences and include your NZ bank details for payment. Invoicing internationally legitimizes your sole proprietor business and expands your client base beyond domestic markets.
Net 14 or Net 30 are most common for NZ sole proprietors, with Net 7 increasingly standard among established service providers. The term you choose depends on your cash flow needs and client expectations. Shorter terms like Net 7 show confidence in your work and improve cash flow. Always state the term clearly on your invoice and include your bank account details for rapid payment. Consider your industry—consulting and professional services often work with Net 14 to Net 30.
If you're GST-registered, your IRD number must appear on every invoice. If not registered, it's not legally required, but including it builds credibility and shows you're a legitimate, established business. Many sole proprietors include it voluntarily even before reaching the GST threshold. It's particularly valuable when invoicing corporate clients who need to verify suppliers for compliance purposes. Your IRD number protects you and reassures clients of your legitimacy.
Break each service into a separate line item on your invoice, listing the description, quantity (often hours or sessions), rate, and subtotal for each. This transparency helps clients understand what they're paying for and makes disputes easier to resolve. Many sole proprietor consultants invoice for strategy work, analysis, meetings, and implementation separately, even on the same invoice. Clear itemization demonstrates professionalism and justifies your rates. It also helps you track which services are most profitable.
Keep copies of all invoices for a minimum of seven years, as required by the IRD. Store them digitally and maintain a backup copy—cloud storage is reliable and audit-ready. Your records should show the invoice number, date, client, description, amount, and GST (if applicable). Organized records make tax time easier, help you identify repeat clients, and support any IRD audit. Many sole proprietors use accounting software that automatically stores invoices and generates reports for compliance.
