Frequently Asked Questions
Yes, GST must be added at the current rate (10%) on most construction invoices if your business is GST-registered. However, some services like certain labor provided by sole traders may be GST-exempt under specific circumstances. Always display the GST amount separately on the invoice alongside your ABN. If you're unsure whether a particular service is GST-taxable, check the ATO website or consult an accountant, as incorrect GST can create compliance issues during tax reconciliation.
Yes, progress invoicing is standard in construction and lets you bill for completed stages rather than waiting until project completion. Each progress invoice should clearly identify which phase or milestone it covers (e.g., "Foundation complete," "Frame erected"). Include details of work completed, materials supplied to date, and amounts held as retention. Progress invoicing improves cash flow and is legally recognized in Australia, though the terms should ideally be agreed in your contract before work begins.
Retention is money withheld by the client until the project is fully complete and defects are resolved, typically 5-10% of the invoice value. The client holds this amount as security and releases it after final inspections and a defects liability period (often 12 months). Your invoice should clearly state the retention percentage, retained amount, and expected release date. Retention is common practice in construction and protects clients, though it affects your cash flow—factor this into your payment terms and pricing.
Issue a separate variation invoice that clearly references the original project contract and invoice number. Describe the additional work, materials, or services requested by the client with corresponding costs. The variation should be documented and ideally signed by the client before work commences to avoid payment disputes. Include this variation invoice with the appropriate GST, and if it's part of a progress billing arrangement, factor it into the retention calculation for that phase.
Show the subcontractor's name, ABN (if GST-registered), and a clear description of work performed. You can invoice the client for this work directly, but the invoice should itemize subcontractor labor separately from your own work for transparency. Ensure you have a written agreement with the subcontractor documenting rates and payment terms. If the subcontractor is not GST-registered, the work may not be GST-taxable—verify their registration status before invoicing the client.
List equipment hire and materials as separate line items with clear descriptions (e.g., "Excavator hire – 3 days @ $450/day" or "Steel reinforcement – 2.5 tonnes @ $800/tonne"). This transparency helps clients understand cost breakdowns and is useful for their own accounting and insurance purposes. Include quantities and rates for each item so clients can verify totals. Separating materials from labor also simplifies future cost tracking and helps identify which components are subject to GST.
Payment terms vary by agreement, but common construction terms are 7-30 days from invoice date or from completion of a stage. Shorter terms (7-14 days) help cash flow, while 30 days is standard for larger clients. State the terms clearly on your invoice and specify payment method (bank transfer, cheque, etc.). Consider including late payment interest terms if permitted by your contract, though this should be agreed beforehand. Shorter terms are particularly important when managing subcontractor payments.
The ATO requires you to keep invoices for at least 5 years from the date of issue. For construction work, it's wise to keep records longer (7-10 years) as disputes and liability claims can extend beyond 5 years, particularly regarding defects or safety issues. Store copies digitally and in hardcopy if possible, alongside photos of completed work, variation approvals, and payment receipts. Good record-keeping protects you in disputes, supports insurance claims, and ensures compliance during tax audits.
