Frequently Asked Questions
A contractor invoice is specifically structured for service-based work common in construction, trades, and consulting. Unlike retail sales invoices, it emphasizes labour hours and rates rather than product quantities. In Australia, contractor invoices must include the contractor's ABN (if registered), GST calculations, detailed service descriptions, project dates, and payment terms. They're designed to satisfy both client accounting records and Australian Tax Office requirements, making them legally distinct from standard sales documentation.
GST registration is not mandatory for all contractors. You're required to register if your annual turnover exceeds $75,000 (as of current thresholds). However, many contractors choose to register voluntarily even below this threshold to claim input tax credits on expenses. If you're not GST-registered, your contractor invoices must clearly state "GST-free" and show the final amount without tax. Your client may actually require you to be registered before engaging you, so confirm their requirements upfront.
An Australian contractor invoice requires your business name and address, ABN (if applicable), invoice number and date, client details, itemized descriptions of work performed with dates, hourly rates or fixed prices, GST amount (if registered), total amount due, payment terms, and payment method details. The ATO considers this a tax record, so accuracy is critical. Missing elements like your ABN or vague service descriptions can create compliance issues. Using a professional template ensures you meet all requirements without accidentally omitting critical information.
Variations in construction work are common and should be documented separately from the original invoice. Issue a variation order or change order request that clearly shows the additional scope, cost, and timeline impact before proceeding with extra work. Once approved, you can invoice the variation as a separate line item or include it as an addendum on the next invoice. Always get written approval before invoicing variations—verbal agreements create disputes. Document approval dates and signatures, as these protect both you and your client for ATO compliance.
Standard Australian contractor payment terms typically range from 7 to 30 days net, with many construction clients expecting longer periods. Negotiate terms based on project size and your cash flow requirements. For larger projects, consider requesting deposits (typically 25–50% upfront) and milestone payments to manage cash flow. Always specify payment terms clearly on your invoice—"Net 14," "Due upon receipt," or "50% deposit, 50% on completion." If clients consistently pay late, include a late payment fee in your terms (allowed under Australian law if reasonable and disclosed).
The Australian Tax Office requires you to keep contractor invoice records for five years from the date you issue them. This applies whether they're paid or unpaid. Store originals or legible copies in a format you can produce if audited—digital copies are acceptable if they're clear and accessible. Five-year retention covers tax investigations and potential disputes. Many contractors maintain electronic versions in accounting software with backups and physical copies for reference. Proper record-keeping demonstrates compliance and protects you during tax reviews.
Yes, itemizing materials and labour separately provides transparency and helps clients understand cost breakdown. For construction projects particularly, this clarity reduces invoice disputes and shows professionalism. Line items might include "Materials – timber framing: $2,400," "Labour – 16 hours @ $95/hour: $1,520," and "Equipment hire: $300." Separate itemization also simplifies GST calculations if materials are subject to different GST treatment than services. Clients appreciate seeing exactly what they're paying for, and it supports your invoice's legitimacy if questioned by the ATO.
First, attempt direct communication—clarify what the client disputes (amount, work scope, quality). If unresolved, refer to your original invoice, variation orders, and any written communication about the work. Request payment within a specified timeframe (typically 7 days). If still unpaid after due date, send a formal payment reminder letter. Document all communications for your records. For significant disputes, consider small claims procedures available through your state's civil court. Prevention through clear invoices, written approval, and transparent terms is always preferable to debt recovery.
