Hourly Invoice Template for Australia

An hourly invoice template is a structured billing document that helps you charge clients for time-based services in accordance with Australian business and tax legislation. This template ensures your invoices meet the mandatory requirements under the A New Tax System (Goods and Services Tax) Act 1999, including proper GST calculations and business identification details.

When do you need this document?

You need an hourly invoice when providing professional services, consulting, or contract work where payment is calculated based on time spent. This includes situations where you're working as a freelance consultant, providing technical services, offering professional advice, or completing project-based work with variable time requirements. The template is particularly valuable when you need to provide detailed breakdowns of hours worked across different tasks or time periods, ensuring transparency with your clients about how their fees are calculated.

Key legal considerations

Your hourly invoice must clearly distinguish between contractor and employee relationships as defined under the Fair Work Act 2009. Include your Australian Business Number (ABN) prominently, as this is mandatory for tax invoices over $75 including GST. Ensure accurate GST calculations and clearly separate GST-inclusive and exclusive amounts. Payment terms should comply with the Payment Times Reporting Act 2020, particularly if dealing with large businesses that must report payment performance. Consider privacy obligations under the Privacy Act 1988 when handling client information, and ensure electronic invoices meet requirements under the Electronic Transactions Act 1999.

Legal requirements in Australia

Australian hourly invoices must include specific elements to be legally valid tax invoices. Display the words "Tax Invoice" prominently, include your business name and ABN, provide the invoice date and a unique invoice number. Client details must include their business name and ABN if they're registered. Clearly describe the services provided, show the hourly rate, total hours worked, and calculate GST separately if applicable. Payment terms must be clearly stated, including due dates and accepted payment methods. For invoices over $1,000, additional requirements may apply including more detailed descriptions of services. Electronic invoices must maintain the same information standards and be accessible to the recipient in a readable format.
