Frequently Asked Questions
Yes, diagnostic and call-out fees are common on repair invoices and should be listed as separate line items. Many repair professionals charge a diagnostics fee to cover investigation time—this helps customers understand the cost of identifying the problem, which may be waived if they proceed with repairs. Call-out fees compensate for travel time and site visit costs, particularly for on-site repairs. These charges should be clearly labeled to manage customer expectations and prevent disputes. Including them upfront builds transparency and demonstrates the full cost of your service delivery.
GST in New Zealand is applied at 15% to both parts and labor costs on repair invoices. Calculate GST on your subtotal rather than on individual line items, then add it to reach your invoice total. If you're GST-registered, you must include your IRD number on the invoice. The customer pays the GST amount on top of the service charge. Clearly separate your subtotal and GST amount so customers see the tax component. This ensures compliance with Inland Revenue requirements and transparency in your billing.
Break down each component separately to show customers exactly what they're paying for. List parts first with descriptions, quantities, and unit prices, then labor hours and rates. Include part names, serial numbers, or reference codes for high-value items so customers can verify what was installed. Labor should show either hourly rates multiplied by hours worked, or flat rates for specific jobs. This itemized approach prevents customer confusion, justifies your pricing, and creates clear records for warranty or dispute purposes.
Issue a quote before any repair work begins to give the customer a cost estimate based on your diagnosis. A quote outlines what you expect to charge but isn't a formal invoice until work is completed. Once you've finished repairs, issue an invoice showing actual costs, which may differ slightly from the quote depending on additional parts discovered or time required. Clearly label documents as "Quote" or "Invoice" to avoid confusion. This protects both you and the customer by setting expectations upfront and formalizing completion.
Yes, including warranty terms on your repair invoice is excellent practice and builds customer confidence. Specify what work is covered, the warranty duration (commonly 30–90 days for parts and labor), and any conditions or exclusions. For example, you might warrant parts for 12 months but labor for 30 days. Note what isn't covered—wear and tear, misuse, or incorrect usage. Clear warranty statements reduce disputes, manage expectations, and demonstrate professionalism. Customers often expect repairs to include some assurance, so documenting this protects both parties.
Keep detailed records of your estimate, quote, and final invoice to support your charges. Have the customer acknowledge the diagnostic findings and approve major work before starting. If disputed, review the quote and invoice side-by-side to explain each charge. Document any additional work discovered during repair that wasn't visible initially. For parts, show the actual cost, markup, and any specialist items. Professional communication and transparency often resolve disputes faster than defensiveness. Maintain records for at least seven years for compliance and future reference.
Yes, if you're GST-registered, your IRD number must appear on every repair invoice. This number identifies your business to Inland Revenue and is required for tax compliance. Include it prominently, typically near your business name and contact details. If you're not GST-registered, you don't need an IRD number on invoices, but you may still want your business registration details for professional presentation. Including your IRD number also signals to customers that you're a legitimate, registered business, which builds trust and credibility.
Record the part name, brand, model, and serial number (if available) for each component installed, especially for high-value items like engines, compressors, or electronics. This documentation proves what work was completed and helps with warranty claims or future repairs. Include the part cost and labor time for installation. Serial numbers also protect you legally by proving you installed genuine parts rather than counterfeit ones. For small consumables like filters or belts, a description is sufficient. Clear documentation strengthens customer confidence and creates a maintenance record.
