Deposit Invoice Template - New Zealand

Yes, GST is applied to deposits in New Zealand and must be included in the deposit amount. The deposit invoice itself is subject to GST at the standard rate (15%), meaning you charge and remit GST on the entire deposit received. This differs from some countries where GST on deposits is deferred until the final invoice. You're required to declare deposit GST on your GST return when received, not when the final invoice is issued. Ensure your deposit invoice clearly shows the GST component so clients understand the total obligation.

Deposit percentages vary significantly by industry and risk level. Construction and renovation projects typically require 30–50%, consulting services 25–40%, and design or custom work 40–50%. Consider your upfront costs, materials you'll purchase, and how long the project runs. Higher deposits protect your business when you're committing resources before payment or project completion. Document your standard deposit policy clearly on the invoice so clients know expectations from the outset. The amount should proportionally reflect the work and materials you'll commit before delivering the final product.

Create a final invoice for the complete project amount, then credit the previous deposit payment. The final invoice should reference the original deposit invoice number and clearly show 'Less: Deposit Paid' with the amount, leaving only the balance due. This maintains transparent financial records and shows clients exactly how their deposit applies. Link both documents in your accounting system. GST was already remitted on the deposit, so the final invoice only attracts GST on the remaining balance due.

State your deposit refund policy explicitly to prevent disputes later. Common approaches include non-refundable deposits once work begins, partial refunds if cancelled early, or full refunds if cancelled before work starts. Ensure your policy is fair and complies with New Zealand consumer expectations. Include refund timelines and circumstances where deposits are non-refundable. Clear written terms protect both parties and reduce conflict if the engagement ends prematurely. This transparency builds trust and demonstrates professionalism.

Clients pay more readily when they understand exactly what the deposit covers and when work begins. Your deposit invoice should detail the specific services or project phases the deposit secures and expected timelines. Include brief descriptions of how the deposit applies—whether it reserves your time, secures materials, or covers setup costs. This clarity reduces payment disputes, sets professional expectations, and improves cash flow reliability. Clear communication strengthens client relationships and demonstrates transparency about how their money will be used.

Deposits become essential when you're committing significant upfront costs, materials, or holding dedicated resources. Construction, renovations, and custom manufacturing routinely require deposits because suppliers need payment before delivery. Consulting and professional services use deposits to secure availability or cover preparation work. Retail typically applies smaller deposits for custom orders. If you're purchasing materials before payment or allocating resources for an extended period, deposits protect your business from cancellation losses. For quick, low-cost services, deposits may be unnecessary.

Record deposits as a liability or advance payment received, not as immediate revenue, since you haven't delivered the service yet. Link the deposit invoice number to your final invoice for straightforward reconciliation. Maintain clear documentation of deposit dates, amounts, GST, and refund status. Keeping deposits separate prevents double-counting income and ensures GST compliance with Inland Revenue. This approach simplifies year-end reconciliation and provides clear evidence of your accounting practices if audited.

Yes, staggered deposits are standard and appropriate for extended projects. Construction and renovation work typically includes deposits at contract signing, when materials are ordered, and before final stages. Invoice each deposit separately with its own invoice number, GST calculation, and clear reference to the project phase. This improves cash flow management and reduces your financial risk over long timelines. Communicate the complete deposit schedule upfront so clients understand the payment structure and can budget accordingly throughout the project.
