Law Firm Invoice Template - Australia

Yes, GST must be included on legal services invoiced to most clients. As a registered GST practitioner, you charge 10% GST on your professional fees and disbursements. However, if you invoice a client subject to GST exemption (certain non-profit entities or government bodies), you'll document this with an exemption note. Always verify your client's ABN and GST registration status before invoicing. Ensure your template clearly separates the GST component so clients understand the tax breakdown, and remember GST remittance is due quarterly to the ATO.

Use tiered rates based on experience and task complexity: senior partners bill higher rates than junior lawyers or paralegals. Your template should itemize each person's time separately, showing the lawyer's name, hours worked, and their applicable rate. For example, a partner's consultation might be $450/hour while paralegal research is $200/hour. This transparency helps clients understand cost allocation and justifies your fees. Many Australian law firms also record time in six-minute increments (0.1 hours) rather than rounding to hours, ensuring accurate billing that reflects actual work performed.

Invoice by matter when clients instruct you on multiple separate matters simultaneously. This means you might send one client multiple invoices—one for their property settlement, another for their commercial dispute, and a third for estate planning. Matter-based invoicing improves clarity because each invoice explains exactly which instructions the costs relate to. Your template should include a matter description or reference number prominently so clients immediately identify what they're being billed for, preventing confusion and payment disputes.

Disbursements are costs you pay on behalf of the client—court filing fees, property searches, land titles office searches, expert reports, or courier services. List these separately from professional fees on your invoice, itemizing each disbursement with its description and amount. Include receipts or reference codes where relevant, and note whether GST applies. Create a distinct line section labeled "Disbursements" or "Expenses" so clients see professional fees and out-of-pocket costs separately. This clarity prevents disputes about what clients are paying for beyond your time.

A retainer is an upfront fee held in trust to cover anticipated legal services. Invoice the retainer initially with clear terms stating it's held in a trust account and will be drawn down as you provide services. Subsequently, send monthly invoices showing work performed and retainer drawdown amounts. Your template should reference the original retainer agreement and show the remaining balance clearly. If the retainer depletes, invoice for additional work owed. If work completes with retainer remaining, arrange refund or credit against future work to prevent misunderstandings.

Legal service descriptions should be specific enough for clients to understand what they paid for, but concise enough to stay professional. Rather than "Legal work - $1,350," write "Contract review and amendments - 3 hours at $450/hour" or "Due diligence research on acquisition target - 8 hours at $320/hour." Include the matter context briefly (e.g., "Property settlement - title searches and reports"). This level of detail helps clients verify billing accuracy, supports their financial records, and demonstrates your value transparently, reducing billing disputes.

Australian law firms typically use 14-day or 30-day payment terms, clearly stated on the invoice. "Payment due within 14 days" is common for established clients; 30 days suits larger corporate clients with approval processes. Include your bank details for direct deposit and specify accepted payment methods. If you offer early-payment discounts or charge late-payment fees, state these clearly upfront and ensure they comply with relevant legislation. Clear payment terms reduce cash flow delays and minimize follow-up confusion around when invoices become payable.

Most Australian Law Societies require invoices to comply with practice rules around billing transparency and trust account management. Invoices must clearly distinguish between professional fees and any trust account transactions or disbursements. Some jurisdictions require itemized billing records to be available if clients request them, supporting audit trails. You should never misrepresent the nature of work or inflate hours. Check your specific Law Society's billing practice rules and keep detailed time records and cost documentation to support every invoice issued.
