Free Australian Invoice Template

Free Australian Invoice Template

Australian businesses operate under a GST system that requires specific invoice content depending on whether you are issuing a tax invoice or a regular invoice. The Australian Taxation Office (ATO) sets clear rules, and getting them right keeps your customers happy and your records audit-ready.

This guide walks through the legal requirements for Australian invoices, GST handling, payment expectations, and how to build a template that works for sole traders, partnerships, and companies across every state and territory.

Tax Invoice vs Regular Invoice

Australia distinguishes between a tax invoice and a regular invoice. The distinction matters because only a valid tax invoice allows your customer to claim a GST input tax credit on their Business Activity Statement (BAS).

If you are registered for GST, you must issue a tax invoice for any taxable sale over $82.50 including GST when the customer requests one. The customer has 28 days to request a tax invoice, and you must provide it within 28 days of the request.

A tax invoice for sales of $1,000 or more must include the document title Tax Invoice, your business name, your Australian Business Number (ABN), the date of issue, a description of each item including quantity, the GST amount payable or a statement that the price includes GST, the GST-inclusive price, the buyer's identity or ABN (for sales of $1,000 or more), and a clear indication of which items are taxable and which are GST-free.

For sales under $1,000, you can omit the buyer's identity. For sales under $82.50 GST-inclusive, no tax invoice is required at all, though you must still keep records.

If you are not registered for GST, you cannot issue a tax invoice. You issue a regular invoice without GST. Your invoice should include the words This invoice does not contain GST or similar wording to make the GST status clear.

Making the wrong type of invoice creates problems for your customer's BAS and your own records. Use the right format based on your GST registration status.

GST in Australia

The Goods and Services Tax (GST) in Australia is a flat 10 percent rate that applies to most goods and services. Unlike Canada or the UK, Australia does not have multiple GST rates. The rate is 10 percent or zero (called GST-free) or the supply is input taxed.

GST-free supplies include most basic foods, some education and health services, and exports. Input-taxed supplies include most financial services and residential rent. Input-taxed means no GST is charged on the supply but you cannot claim GST credits on related expenses.

You must register for GST if your annual GST turnover is $75,000 or more for businesses, or $150,000 or more for nonprofits. Taxi and ride-share drivers must register regardless of turnover. Below the threshold registration is voluntary but often beneficial because registered businesses can claim GST credits on business expenses.

Once registered, you charge GST on taxable supplies, claim credits on business purchases, and lodge a BAS quarterly or monthly depending on your size.

On your invoice, show GST clearly. The standard approach is to show each line item at the GST-inclusive price with a clear statement at the bottom that the total price includes GST and the GST amount. For example, a $1,100 invoice would show: Total $1,100.00, GST included $100.00. Alternatively, you can show net prices with GST added as a separate line: Net $1,000.00, GST 10% $100.00, Total $1,100.00.

If your invoice contains a mix of taxable and GST-free items, you must clearly indicate which items are taxable and which are not.

For exports, the supply is generally GST-free. Mark the invoice clearly with text like GST-free export.

Australian Business Number (ABN) Requirements

The ABN is a unique 11-digit number issued by the ATO. Almost every Australian business needs one, and it must appear on every tax invoice you issue.

If you do not quote an ABN on your invoice to another business, the customer is required to withhold 47 percent of the payment under the No ABN Withholding rules and remit it to the ATO. This means an invoice without an ABN often gets paid 53 percent of the invoiced amount, with the rest going to the tax office. You then have to claim the withheld amount back through your tax return, which is slow and frustrating.

Get an ABN before you start invoicing if you are not exempt. Application is free through the Australian Business Register and takes minutes online.

If you are a sole trader using your Tax File Number rather than registering an ABN, you must complete a Statement by a Supplier form for each customer to avoid the 47 percent withholding. This is administratively burdensome and most sole traders just get an ABN.

For companies, also include the Australian Company Number (ACN) where applicable. The ACN is a 9-digit number issued by ASIC. Some companies have both an ABN and an ACN, with the ABN being the ACN plus a two-digit prefix.

Place the ABN prominently on the invoice, typically in the header near the business name and address.

Industry-Specific Considerations

Different Australian industries have additional invoice requirements or common practices.

The construction industry operates under specific rules in some states. Some states require tradies to include their license number on every invoice. Building and construction services for residential customers often have specific consumer protection requirements.

Professional services like accounting, consulting, and legal are typically subject to standard 10 percent GST. Some financial services and certain medical services are input taxed or GST-free. Check the specific rules for your profession.

Freelance and creative services are generally subject to 10 percent GST if you are GST registered. If your annual turnover is under $75,000 and you are not registered, your invoices do not include GST and must clearly state this.

Retail and ecommerce businesses must apply GST to sales to Australian customers. Cross-border sales to international customers are generally GST-free as exports, with documentary proof of export required. Imported low-value goods sold to Australian consumers through marketplaces have specific GST rules that the marketplace often handles.

Rideshare drivers, food delivery riders, and other gig economy workers must be GST registered regardless of turnover. Their platform invoices and earnings reports should reflect this.

Nonprofits and charities have special GST concessions and may use simplified invoicing for certain transactions. Check ATO guidance for your specific situation.

Payment Terms and Methods in Australia

Australian payment expectations are generally Net 30 for business-to-business invoices, though Net 14 is common for smaller engagements and many service businesses. Many large corporates push for Net 60 or longer, which can be challenging for small business cash flow.

The Business Payments Code, and broader government efforts to speed up payment to small business, are pushing larger Australian companies toward faster terms. The Payment Times Reporting scheme requires large businesses to publicly report their payment performance to small business suppliers.

Accepted payment methods in Australia include the New Payments Platform (NPP) via PayID, which is the fastest and most popular option for small business invoice payments. PayID lets payers send money to an email address, phone number, or ABN rather than a BSB and account number. EFT (electronic funds transfer) by direct bank transfer is also standard. BPAY is widely used for invoice payments, particularly to larger businesses with BPAY codes. Credit card payments through Stripe, Square, or similar processors speed up checkout. Cheques are increasingly rare.

Late payment interest on Australian invoices is commonly set at the small business rate, which is the RBA cash rate plus a margin specified in your contract, often 2 to 5 percent above base. Statutory rules in some states permit interest at the prescribed rate even without explicit contract terms, but contractual terms provide cleaner enforcement.

For cross-border invoices, SWIFT wire transfer is standard for larger amounts. Currency conversion fees vary by bank, so mark the invoice currency clearly.

Build Your Australian Invoice with Eonebill.ai

Eonebill.ai supports Australian businesses with proper GST handling, ABN compliance, and integration with Australian payment methods. Use the invoice generator at /free-tools/invoice-generator to build a template that includes your ABN, business name, and standard line items.

The platform automatically applies the 10 percent GST rate to taxable supplies and handles GST-free and input-taxed items separately. The tax invoice label is added automatically when you are GST registered, and all required fields for a valid tax invoice are checked before issuing.

For sole traders, partnerships, and companies, the platform supports the correct legal entity setup. Companies can include their ACN alongside their ABN. GST registration status is configurable, and the invoice format adjusts automatically depending on whether you are GST registered.

BAS-ready data is exported in a format compatible with most Australian accounting software including Xero, MYOB, and QuickBooks Australia. This makes quarterly or monthly BAS lodgment fast and accurate.

For multi-currency invoicing to international clients, Eonebill supports AUD, USD, EUR, GBP, NZD, and many others. Exchange rates are pulled from market data automatically, and GST-free export designation is applied to non-Australian sales.

Set up recurring invoices for retainer clients, automatic payment reminders for overdue accounts, and integrated PayID, BPAY, EFT, or card payment options so clients can pay directly from the emailed invoice.

Review tier options at /pricing and pick the plan that matches your invoice volume. Australian small businesses typically start on the free or starter tier and grow as their business expands.

A properly built Australian invoice template handles ABN compliance, GST calculation, and ATO requirements without making you the bottleneck. Build yours once and let Eonebill carry the load on tax invoicing, BAS preparation, and payment processing.

There is also a strategic dimension to invoicing in the Australian market. The Payment Times Reporting scheme requires large businesses to publicly disclose their payment performance to small business suppliers, which creates social pressure for faster payment. Small business advocacy groups in Australia, including the ASBFEO (Australian Small Business and Family Enterprise Ombudsman), have been pushing for faster payment as a matter of public policy. Small business owners can leverage this momentum by referencing payment time commitments and reporting late-paying clients to the relevant body if appropriate. While individual reports rarely produce immediate enforcement action, the cumulative pressure has been moving the entire ecosystem toward faster payment over the past several years.

For Australian businesses serving international clients, particularly in Asia-Pacific, currency and payment method handling matter significantly. Singapore, Hong Kong, Japan, and the broader ASEAN region are major trading partners for Australia. Each has different banking conventions, preferred currencies, and timing expectations. A US client invoiced in USD with ACH payment, a UK client invoiced in GBP with Faster Payments, and a Japanese client invoiced in JPY with wire transfer represent three different operational workflows. Eonebill.ai handles all of these through multi-currency invoicing and integrated payment options, but understanding the differences helps you set realistic expectations and design efficient processes.

Finally, the Australian small business ecosystem benefits from a strong professional services industry. Most small business owners work with a registered tax agent or BAS agent for compliance, an external bookkeeper for ongoing record-keeping, and sometimes a separate accountant for strategic advice. Building strong working relationships with these professionals pays dividends in tax savings, compliance peace of mind, and strategic insights. Your invoicing system should support seamless collaboration with these advisors, including read-only access for your bookkeeper, BAS-ready exports for your tax agent, and management reports for your accountant. Eonebill's permission system supports these multi-stakeholder workflows without compromising security.

A closing thought is that Australian business culture generally values straightforward communication and clear documentation. The invoice that is direct, well-organised, and free of unnecessary jargon will be received well by Australian clients across industries. Build your template with that cultural preference in mind, and the result will both meet ATO requirements and resonate with the way Australian businesses prefer to operate. Clear documentation, fair terms, and prompt follow-up are the marks of a business worth dealing with in the Australian market. These cultural norms apply equally to small operators serving local clients and to growing businesses expanding across the country or internationally. A consistent professional presentation builds trust at every stage of business growth.
