What is a Hourly Invoice?

Frequently Asked Questions
What is an hourly invoice and when do I need one?
An hourly invoice is a billing document that charges clients for time-based services rather than a fixed project fee. You need one when payment is calculated on hours spent, for example as a freelance consultant, technical service provider, subcontractor, or when completing contract work with variable time requirements. It lets you set out a detailed breakdown of hours worked across different tasks or periods, so clients can see exactly how their fee was calculated. In Australia it also doubles as a tax invoice when it meets Australian Taxation Office requirements, including GST details and business identification, under the A New Tax System (Goods and Services Tax) Act 1999.
What must an Australian hourly tax invoice include?
To be a valid tax invoice in Australia, an hourly invoice should display the words "Tax Invoice" prominently and include the following. Your business name and Australian Business Number (ABN). The invoice date and a unique invoice number. The client's business name, and their ABN if they're registered. A clear description of the services provided. The hourly rate, total hours worked, and the GST calculated separately where it applies. Payment terms, including due dates and accepted payment methods. For invoices over $1,000, more detailed service descriptions may apply. These requirements flow from the GST Act 1999, so specifics can vary with your circumstances.
Do I need to include my ABN on the invoice?
Yes. Under the A New Tax System (Goods and Services Tax) Act 1999, your Australian Business Number (ABN) must appear prominently on a tax invoice, and it is mandatory for tax invoices over $75 including GST. Without an ABN, the business paying you may be required to withhold tax from the payment. If your client is registered for GST, their business name and ABN should also be shown. Displaying the correct business name alongside the ABN matters under the Business Names Registration Act 2011. If you aren't registered for GST, your document is a standard invoice rather than a tax invoice.
When do I have to charge GST on an hourly invoice?
GST generally applies if your business is registered for GST, which is required once your annual turnover reaches the Australian Taxation Office registration threshold. On a tax invoice you should calculate GST separately and clearly distinguish GST-inclusive and GST-exclusive amounts so the client can see the tax component. If you aren't registered for GST, you shouldn't add it, and the document is an ordinary invoice rather than a tax invoice. GST treatment can depend on the type of service and your turnover, so check your registration status with the ATO and seek advice if your situation is complex.
How is an hourly invoice different from a fixed-fee or job invoice?
An hourly invoice bills by time, so it lists the hourly rate and total hours worked, often broken down by task or date. A fixed-fee or quoted job invoice charges a single agreed amount for the whole piece of work regardless of hours. The two share the same tax-invoice requirements under the GST Act 1999, including ABN, GST and invoice number, but the hourly format gives clients line-by-line transparency on how time translates to cost. Hourly suits consulting, subcontracting and variable-scope work; fixed-fee suits clearly defined deliverables. Many contractors use whichever matches the engagement, and some combine both on one invoice.
Can I send an hourly invoice electronically?
Yes. Electronic invoices are recognised under the Electronic Transactions Act 1999, provided they carry the same information as a paper tax invoice and are accessible to the recipient in a readable format. That means an emailed PDF or a digital invoice must still show "Tax Invoice", your business name and ABN, the date, a unique invoice number, the service description, hours, rate, any GST, and payment terms. When handling client details, keep your privacy obligations under the Privacy Act 1988 in mind. Keeping copies of issued invoices also supports your record-keeping for tax purposes. An editable template helps keep every electronic invoice consistent.
About the Hourly Invoice
An hourly tax invoice template is a structured billing document that helps you charge clients for time-based services in line with Australian business and tax legislation. It gives you a ready format to create, send and record invoices that meet the mandatory fields for a valid tax invoice under the A New Tax System (Goods and Services Tax) Act 1999, including proper GST calculations and business identification details. If you bill flat project fees rather than time, the master invoice template covers the same ATO standards in a general format.
What is an Australian tax invoice template?
An Australian tax invoice template is a reusable document that already includes every field the ATO expects on a compliant tax invoice. You fill in your business name and ABN, the customer's details, the services provided, the hourly rate and hours worked, then the template calculates the GST and total. Starting from a template means you issue a consistent, correctly formatted invoice every time instead of rebuilding one from scratch.
When do you need this document?
You need an hourly invoice when you provide professional services, consulting or contract work where payment is based on time spent. This covers freelance consulting, technical services, professional advice and project-based work with variable time requirements. The template is useful when you need to give customers a detailed breakdown of hours worked across different tasks or periods, so they can see exactly how their fees are calculated before they pay. For self-employed work billed per engagement, the independent contractor invoice template is a close alternative.
How do you create and send an hourly tax invoice?
Start from the template, then add your business name, ABN, a unique invoice number and the invoice date. List each block of hours with a short description, apply your hourly rate, and let the GST line calculate against the subtotal. Add your customer's business name, billing address and ABN if they are registered, set clear payment terms and due dates, and list the payment methods you accept. You can then send the invoice by email as a readable PDF, which keeps a record both parties can refer back to and makes it easy to track what has been paid and what is still outstanding.
Key legal considerations
Your hourly invoice should reflect the contractor relationship as defined under the Fair Work Act 2009 rather than an employment one. Include your Australian Business Number (ABN) prominently, since it is mandatory for a tax invoice of $75 or more including GST. Calculate GST accurately and keep GST-inclusive and GST-exclusive amounts clearly separated. Set payment terms that align with the Payment Times Reporting Act 2020, which matters when you supply large businesses that report payment performance. Handle customer information in line with the Privacy Act 1988, and make sure any electronic invoice meets the Electronic Transactions Act 1999.
What must an Australian tax invoice include?
To be a valid tax invoice, an Australian hourly invoice needs each of these elements:
- The words "Tax Invoice" shown clearly on the document.
- Your business name, ABN and address.
- The invoice date and a unique invoice number.
- The customer's business name and address, and their ABN if they are registered.
- A clear description of the services or products supplied, with the hourly rate and total hours worked.
- The GST amount shown separately where GST applies.
- Payment terms, including the due date and accepted payment methods.
For a tax invoice of $1,000 or more, the ATO expects the buyer's identity or ABN to be shown. Invoices sent online must carry the same information and reach the customer in a readable format they can keep as a record.
How does a tax invoice differ from a credit note?
A tax invoice bills your customer for hours worked or products supplied. A credit note (sometimes called an adjustment note) does the opposite: it reduces an amount already invoiced, for example when you correct an overcharge or agree a partial refund. If you need to amend an invoice you have already sent, issue an adjustment note that references the original invoice number rather than editing the original, so your records and GST reporting stay accurate.
Can you use a free invoice template online?
Yes. You can start from this free hourly tax invoice template, fill in your details online, and download or email the finished document to your customer. Because the template already holds the ATO-required fields, you get a consistent, compliant invoice each time and a clear record of what you have billed and been paid, with less admin than building a new invoice by hand.
