Builders Invoice Template - Australia

Yes, if you're registered for GST (turnover over $75,000 for most businesses), you must charge GST at 10% on construction work unless specifically exempt. This includes labor, materials, and services. Your invoice must clearly show the GST-inclusive total and the GST amount separately so clients can claim the input tax credit. Most construction invoices display the subtotal, then GST, then the final amount due.

Yes, progress invoicing is standard practice in Australian construction. You can invoice at different stages—foundation, framing, lockup, fit-out—rather than waiting until completion. Clearly state which stage the invoice covers and what percentage of the total project is complete. This maintains cash flow during longer builds and creates clear records of work completed and payment received at each milestone, protecting both you and your client.

Your invoice must include your business name, ABN, full address, invoice number and date, the client's details, a description of work performed, itemized costs, payment terms, and your preferred payment method. If GST-registered, show GST separately. Include a due date and payment instructions. Meeting these requirements protects you legally and ensures clients can process payments through their accounting systems without delays or queries.

Most Australian builders offer 14 or 30-day payment terms, with 14 days standard for residential work and 30 days for larger commercial projects. Many require a deposit (25–50% of total cost) before starting work. Clearly state your terms on every invoice to prevent disputes. Consider offering a 2% discount for payment within 7 days if cash flow allows, or requiring deposits from new clients to reduce the risk of non-payment on larger jobs.

Yes, itemizing labor and materials separately provides transparency and helps clients categorize costs correctly for their accounting. Clients often have different tax treatments or budget codes for each category. Breaking down work by trade (framing, plumbing, electrical) or by project phase also makes it easier to track completion and identify disputes before they escalate. This detail protects you if payment disputes arise later.

If you're GST-registered, your ABN must appear on every invoice—it's a legal requirement. Your ABN, business name, and address should be clearly visible, typically in the header or footer. Clients need your ABN to claim the input tax credit on GST, so omitting it creates accounting problems for them. Even if you're not GST-registered, including your ABN is professional practice and builds client confidence.

A retention clause allows clients to hold back a percentage of payment (typically 5–10%) until practical completion, protecting them against defects and ensuring quality. Retention is standard in construction, especially for larger projects. Your invoice should clearly state if retention applies, the retention percentage, and when it will be released—usually 30 days after practical completion. This protects you by keeping clients motivated to pay promptly.

Respond promptly with detailed documentation: photos, site reports, quotes, and purchase receipts proving work completed or materials supplied. Your invoice should already itemize work by date or phase to resolve disputes quickly. Review your original quote or contract to confirm pricing matches what you invoiced. For variations to the original scope, reference any variation orders. If disputes persist, contact your state's building or contractor board for guidance on resolution.
