Frequently Asked Questions
If you're GST-registered, you must add 15% GST to your hourly rates on the invoice. Show your hourly rate excluding GST, multiply by hours worked, then add GST to the subtotal. For example, 10 hours at $80/hr equals $800, plus $120 GST totals $920. If you're not GST-registered, you can include GST in your quoted rate, but must clearly state whether rates are GST-inclusive or exclusive. Check your registration status with Inland Revenue to ensure compliance.
Most New Zealand professionals bill in quarter-hour (15-minute) or half-hour increments. Quarter-hour is standard for consulting, design, and specialized services where precision matters. Half-hour increments work well for larger projects or routine tasks. Full-hour minimums are less common unless genuinely justified. State your chosen increment clearly in invoice terms and agree with clients beforehand. Consistency across all your invoices demonstrates professionalism and prevents payment disputes.
Provide enough detail for clients to immediately recognize what they're paying for without cluttering the invoice. Instead of listing every minute, group work by task or project phase. For example, "Website Design Consultation – 8 hours" works, but adding "includes wireframe design and client scope meeting" adds valuable context. If work spans multiple weeks, break it down by date or deliverable. The goal is demonstrating clear value—clients should understand the work performed and consider it reasonable compensation.
Use hourly invoicing for projects with undefined scope, evolving requirements, or ongoing services—typical for consulting, design revisions, support, and development work. Hourly rates protect you from scope creep and ensure fair pay when timelines are uncertain. Fixed fees work better for well-defined projects with stable requirements. Many New Zealand professionals combine both approaches: a retainer for baseline hours plus hourly rates for additional work, giving clients predictability while protecting you from underestimation.
Yes, absolutely. List each service separately with its corresponding rate and hours. One line might show "Design Work – 10 hours @ $90/hr" while another shows "Project Management – 3 hours @ $75/hr." Rate variation by expertise or task type is professionally accepted when clearly presented. Ensure rates are justified by experience level and service complexity—clients understand why specialized work costs more. Confirm your rate structure in the service agreement before sending the invoice.
Round consistently according to your stated terms. If your minimum increment is 15 minutes, round to 0.25, 0.5, 0.75, or 1.0 hours. Some professionals round up generously to simplify calculations; others round to nearest. The best approach: show actual hours (8.5 instead of rounding to 8 or 9) for complete transparency—clients can see exactly what they're paying for. Document your rounding method in terms or service agreement. Consistency prevents disputes and builds trust with repeat clients.
7–14 days is standard for New Zealand hourly invoices, though terms vary by industry and client size. First-time clients or smaller businesses often pay within 7 days; larger corporates may negotiate 14–30 days. Freelancers sometimes require upfront deposits for extended projects. Specify payment terms clearly on the invoice ("Payment Due: 7 days from invoice date") and include your bank details for direct transfer. Late payment penalties can encourage faster settlement. Agree on terms before work begins to avoid misunderstandings.
Monthly invoicing is standard practice for ongoing hourly work in New Zealand, balancing administrative simplicity with reasonable cash flow. Weekly invoicing suits short-term contracts or roles with significant hour fluctuations. Project-based invoicing works if work is discrete and completes quickly. Discuss billing frequency with clients before starting work—some prefer monthly for accounting efficiency, others want regular updates. Whatever you choose, send invoices promptly when the period ends. Regular, predictable invoicing demonstrates professionalism and accelerates payment.
