Truck Repair Invoice Template - Australia

Separating labour and parts creates transparency and prevents billing disputes. List each part with its unit cost and quantity, then specify labour as hours multiplied by your hourly rate. For example, an engine overhaul might show: 'Gasket set $120 × 1 + Hydraulic fluid $85 × 2', followed by 'Labour: 8 hours @ $95/hr = $760'. This breakdown helps clients understand their investment, simplifies tax records for deductible labour versus materials, and demonstrates professionalism. Clear itemization also makes warranty claims easier to process and justifies charge variations.

Yes, diagnostic charges are standard practice and should be invoiced upfront. Many Australian repair shops charge $50–$150 for initial diagnostic inspection, which identifies the fault without committing to repairs. You can credit this fee toward repair costs if the customer proceeds, or charge it fully if they decline repairs. This protects your labour investment and establishes fair expectations. Clearly state on the invoice whether the diagnostic fee is refundable, creditable, or standalone. Most clients understand that complex truck diagnostics require genuine expertise and justify the cost.

Include the vehicle registration number, Vehicle Identification Number (VIN), make, model, year, and current odometer reading on every invoice. These details ensure accurate record-keeping, prevent billing errors, and help clients track maintenance history. For fleet operators, registration number is essential for matching invoices to vehicles in their records. The odometer reading also documents service intervals, which is valuable for warranty claims and compliance purposes. Many repair shops note the vehicle's colour and specific identifying features to eliminate confusion, especially when servicing multiple identical trucks from the same operator.

You have two options: issue separate invoices for each visit, or combine all work on a single invoice with visit dates clearly noted against each line item. For extended repairs requiring multiple appointments, combining invoices simplifies your client's accounting but risks confusion. Alternatively, separate invoices create clear audit trails and may better reflect payment schedules. Note the work dates prominently to avoid ambiguity. If you provide labour estimates before work begins, reference the estimate number on the final invoice. This approach is especially useful for warranty tracking, where dates determine coverage periods.

Markup practices vary, but transparency builds trust. Display parts at your cost with a standard markup percentage (e.g., 35–50% is common), or simply show the final price without revealing cost. Itemizing parts separately from labour helps clients understand where money goes and differentiates your service value. Some shops list 'Parts: $500' and 'Labour: $400' without showing markup, while others detail each component. The key is consistency—choose one approach and use it across all invoices. This clarity also simplifies GST calculations and makes it easier for clients to budget for future repairs.

Payment terms depend on your client relationship. For new or one-off customers, cash on completion or payment due on invoice is standard. Established clients typically receive 14-day payment terms, while fleet operators may negotiate Net 30 or even Net 45. Specify payment terms clearly on every invoice, including accepted payment methods (bank transfer, credit card, cash). Include your bank details or preferred payment platform. For large repairs exceeding $5,000, requiring a deposit upfront is reasonable and protects your cash flow. Late payment penalties and interest, if applicable, should be documented in your standard terms and conditions.

GST at 10% applies to all truck repair services in Australia, including labour, diagnostic fees, parts, and materials. Your invoice must show the GST amount separately from the subtotal, with the total including GST clearly displayed. If your business is GST-registered, you must collect GST on all invoices and remit it to the ATO. Parts are not GST-exempt; even imported components are subject to GST. If a customer is GST-exempt (which is rare), note this clearly on the invoice. Always verify your registration status with the ATO and consult a tax professional about your specific obligations.

Document warranty details on your invoice to set clear expectations and prevent disputes. Include the warranty period (e.g., '12 months parts, 6 months labour'), what's covered (e.g., manufacturing defects only, not wear items), and any exclusions (e.g., parts damaged by customer misuse). Note whether warranty applies only to the specific repair or the entire vehicle. Some shops warrant parts at full replacement cost, others at discount labour rates. Include your contact process for warranty claims. A simple statement like 'All repairs carry 12-month parts warranty; labour warranty limited to 6 months' is sufficient. This documentation protects both you and the customer.
