Free Invoice Template Generator for Australian Businesses

If you're registered for GST, you generally must issue a tax invoice for sales over $82.50 (inc GST). Tax invoices generally include the words "Tax Invoice" and show GST amounts separately. Learn more about ATO tax invoice requirements.

If you're not registered for GST, use a regular invoice (sometimes called a "recipient-created tax invoice" or RCTI in specific cases).

Have ready:

• Your business name and ABN
• Your business address and contact details
• Client's name and address
• Description of goods or services provided
• Quantities, unit prices, and totals
• Payment terms (e.g., Net 30 days)
• Bank account details for payment

Use a template, generator (like this one), or accounting software. Consistency matters—use the same template for all invoices to maintain a professional brand image.

Templates should include your logo, business colors, and be clear and easy to read.

Every invoice needs a unique identifier. Common formats:

• Sequential: INV-001, INV-002, INV-003...
• Date-based: 2026-01-001, 2026-01-002...
• Client-based: ABC-001, ABC-002 (for client ABC)

Never reuse invoice numbers. Keep them in order so you can track payments and identify missing invoices.

At the top of your invoice, include:

• Your business logo (optional but professional)
• The word "INVOICE" or "TAX INVOICE" in large, clear text
• Invoice number
• Invoice date
• Due date or payment terms

Seller (your business):

• Business name
• ABN (required for tax invoices)
• Address, email, phone

Buyer (client):

• Client name or business name
• Address
• Contact details (optional but helpful)

List each product or service with:

• Description: Clear and specific (e.g., "Web design consultation - 3 hours")
• Quantity: Number of units, hours, or items
• Unit price: Price per unit (e.g., $100/hour)
• Line total: Quantity × Unit price

Avoid vague descriptions like "Services rendered"—be specific so clients know exactly what they're paying for. If you're billing for staff time, consider using a shift cost calculator to ensure you're covering your labour costs.

Show the breakdown clearly:

• Subtotal: Sum of all line items
• GST (10%): Only if you're GST-registered and issuing a tax invoice
• Total: Subtotal + GST

For tax invoices, GST must be shown separately. The ATO requires this for businesses to claim input tax credits.

Make it easy for clients to pay you. Include:

• Bank name
• BSB and account number
• Account name
• Payment reference (e.g., invoice number)
• Alternative payment methods if applicable (PayPal, Stripe, etc.)

Clear payment instructions reduce delays and payment errors.

Save your invoice as a PDF (not Word or Excel) to ensure formatting stays consistent across devices.

Email it to your client with a brief, professional message:

Keep a copy of every invoice you send. You must retain tax invoices for 5 years (ATO record keeping requirement).

Track payment status:

• Unpaid: Send a friendly reminder a few days before the due date
• Overdue: Follow up promptly with a polite email or phone call
• Paid: Mark as paid and thank the client

Use accounting software or a simple spreadsheet to track invoice status. Late payments hurt cash flow—stay on top of follow-ups. For service businesses billing clients for staff time, consider rostering software that tracks hours and integrates with accounting systems like Xero and MYOB.
