Frequently Asked Questions
Yes, separating labour and materials helps clients understand value and justifies your costs. Labour should show hourly rates or fixed rates for specific tasks (installation, inspection, rewiring), while materials list components, fixtures, and supplies used. This transparency builds trust and reduces payment disputes. New Zealand clients increasingly expect this breakdown, and it's essential if you're claiming GST—each component may have different GST implications or be purchased with different GST treatment.
Yes, callout fees are standard industry practice for emergency electrical work, particularly outside business hours. Your invoice should separately itemize the callout fee (often $100–$200 in New Zealand) plus labour and materials. This covers your availability and rapid response. Clearly label emergency charges on the invoice so clients understand the additional cost. Include the specific call-out time on the invoice to justify the premium rate and meet professional invoicing standards.
If you're GST-registered, you must add 15% GST to all labour, materials, and callout fees on your invoice. Show the subtotal, then GST amount separately, then the total including GST. Your invoice must display your GST registration number. Some materials purchased for resale may be subject to different GST treatment—keep records of all purchases. If you're not yet GST-registered ($60,000 annual turnover threshold), state "GST not applicable" on your invoices to avoid confusion.
Your electrical invoice must include: your business name and GST registration number (if applicable), invoice number and date, client name and address, itemized description of each service, quantity and rate, GST calculation (if registered), total amount due, and your payment terms. For safety inspections or certification work, consider adding your licence number or electrician qualifications. Include a brief description of the electrical work (e.g., "Rewiring kitchen circuits," "Power point installation") so clients have clear documentation of what was completed.
Travel time is typically included in your callout fee or hourly rate rather than charged separately. However, if a job involves significant travel (e.g., outside your service area), you can add a separate travel charge or increase your callout fee. Be transparent about this on your invoice and in your initial quote. Some electricians include travel time in materials handling or site inspection fees. Consistency matters—establish clear travel policies in your terms and communicate them upfront to avoid invoice disputes.
List materials and supplies as individual line items with description, quantity, and price. This might include cables, circuit breakers, fixtures, outlets, switches, or LED lights. You can add a reasonable markup (typically 15–30%) to cover your procurement, storage, and handling costs. Be specific: instead of "electrical materials – $245," itemize "4-core cable – 50m ($120), LED downlights – 5x ($100), power outlets ($25)." Transparency prevents client pushback and demonstrates professional practice, especially for larger residential projects.
Most electricians in New Zealand use "due on receipt" or "net 7–14 days" for residential clients and "net 30 days" for commercial clients. Clearly state your payment terms on every invoice. For emergency or callout work, requesting immediate or same-day payment is reasonable and helps your cash flow. Include your payment methods (bank transfer, EFTPOS, cash) and bank details. Late payment penalties can be specified in your terms—consider offering a small discount for early payment to encourage faster settlement.
Safety inspections verify compliance with New Zealand electrical codes and protect both you and the client legally. Itemizing them separately ($150–$250) shows clients the value of this service and justifies the cost. Inspections may be required for real estate transactions, insurance claims, or pre-purchase assessments—clients need clear visibility. This line item also documents that qualified inspection work occurred, which is important for your professional liability and the client's property records. It strengthens the credibility of your invoice.
