Proforma Invoice Template - Australia

A proforma invoice is not a legally binding contract—it's a preliminary cost proposal. It provides your client with an estimated price for services or goods before you issue a formal invoice. Once accepted, it outlines your client's expectations for the final billing. The actual legal obligation begins when the client approves the proforma and you proceed with the work. This distinction matters for Australian businesses because it clarifies that the document is tentative until both parties commit to the transaction.

A proforma invoice is more formal than a quote and includes invoice-like details such as invoice numbering, ABN, and payment terms. Use a proforma when you've discussed specifics with the client and want to provide a structured breakdown of costs before commencing work. For simple price requests, a quote may suffice. Proformas work best for complex projects, large orders, or when you need to establish payment expectations upfront. They're standard practice in Australian B2B transactions where formality and paper trails matter.

Yes, if you're GST-registered, you must include GST on a proforma invoice. The GST must be itemized separately from the subtotal, showing the tax amount and total. This ensures your client understands the final cost and aligns with Australian Tax Office requirements. If you're not GST-registered, clearly state this on the proforma. Omitting or incorrectly calculating GST can create confusion when the final invoice is issued, so accuracy here prevents billing disputes later.

Your proforma must include your business name, ABN, and contact details; the client's name and address; an invoice number and date; itemized services or goods with quantities and rates; GST calculations if applicable; and payment terms. Australian formatting standards require clear company identification and tax details. The template should also include payment methods accepted and any conditions. This completeness ensures the document is professional and provides all information your client needs to make an informed decision.

Once your client accepts the proforma and you've completed the work, create a final invoice using the same structure but with a new invoice number and the delivery date. Retain the proforma reference number for your records. The final invoice should match the proforma amounts unless there were agreed changes. This linked numbering creates a clear audit trail for both you and your client. In Australian business practice, this connection helps resolve any future payment discrepancies or disputes.

While there's no fixed Australian legal period, proformas typically remain valid for 7 to 30 days, depending on your terms. You should state the validity period clearly on the template to set client expectations. Prices for materials or services may change, so limiting validity protects you from unexpected cost increases. If a client wants to proceed after expiry, reissue a new proforma with updated pricing. This practice is standard in Australian invoicing and prevents billing complications.

Yes, your ABN should be clearly visible on the proforma. It's required for tax and business identification purposes and builds credibility with Australian clients. Displaying your ABN reassures clients that you're a registered business and helps them process the document through their accounting systems. Include it alongside your business name and contact details. This transparency is particularly important for B2B transactions, where clients often need ABN details for their records and tax compliance.

Yes, sending a proforma via email is standard practice and legally acceptable in Australia. A signature isn't required for the proforma itself, though some businesses add a digital or printed signature to enhance professionalism. The key is ensuring the client receives the document and can track it in their system. For important projects, request written confirmation (email reply) that the client accepts the proforma terms. This creates a clear record and prevents misunderstandings about agreed pricing.
