Frequently Asked Questions
All HVAC invoices issued in New Zealand must display your GST registration number and calculate GST at 15% on taxable supplies (unless you're not GST-registered). Show the GST-exclusive subtotal, the GST amount separately, and the total including GST. This is required by Inland Revenue and essential for your records. If you haven't registered, state "GST not applicable" on the invoice. Keep records of all invoices for seven years for compliance.
Break down your heat pump invoice into distinct labor and material components. Include the unit cost and quantity (e.g., Mitsubishi 7.1kW heat pump × 1), installation labor hours, ductwork and sealing, electrical connection and wiring, system commissioning and testing, refrigerant top-up if needed, thermostat programming, and any additional components like grilles or filters. Clear itemization helps clients understand what they're paying for and reduces billing disputes.
Yes, separating labor and materials is best practice for HVAC invoices in New Zealand. It provides transparency, helps clients understand value, and is essential for warranty purposes—many manufacturers require proof of professional installation separate from component costs. This breakdown also simplifies your accounting and GST calculations. Some clients may need to track these separately for insurance or accounting purposes, making this separation valuable.
For multi-stage HVAC projects, you can issue partial invoices as work completes. Invoice when the installation phase finishes, another when commissioning is complete, or when major milestones are reached. Clearly date each invoice, reference the job number, and note the specific work completed in that stage. This approach improves cash flow, shows progress to your client, and prevents disputes about incomplete work or unclear scoping.
Yes, you can include emergency, call-out, or after-hours surcharges on your HVAC invoice, provided they're disclosed in your initial quote or terms. Common practice in New Zealand is to add a surcharge percentage (e.g., 25-50%) for work outside standard business hours or a flat call-out fee. Document these clearly on the invoice and ensure your customer agrees beforehand to avoid disputes. Make this transparent in your invoice description.
Include warranty details prominently on your HVAC invoice to protect both you and the client. Document the equipment manufacturer warranty (e.g., Mitsubishi compressor warranty), your labor warranty period, and any workmanship guarantees. Specify warranty terms clearly—is it 1 year, 5 years, or longer? Mention what's covered (e.g., parts, labor) and any exclusions. This prevents misunderstandings and is important if warranty claims arise later.
For maintenance contracts, issue invoices at the agreed interval—monthly, quarterly, or annually. List the services performed (filter changes, system inspection, cooling efficiency check) or state "Monthly maintenance contract—July 2025" with the flat fee. Keep detailed records of services completed in case clients dispute coverage. Include the contract reference number on invoices to link them to the signed agreement and simplify record-keeping.
Yes, including equipment details like model numbers, serial numbers, and capacity (e.g., Mitsubishi 7.1kW) is essential for HVAC invoices. This information supports warranty claims, helps technicians during future service calls, and protects you if disputes arise about what was installed. It also ensures accurate record-keeping for your business and helps clients with their own asset tracking. Many manufacturers require this for warranty registration anyway.
