Email is the standard way to deliver invoices in Australia. Send a PDF attachment (never an editable Word or Excel file) with a short, professional message.
How to send an invoice by email: 1. Finalise the invoice and export as PDF 2. Use a clear subject line: "Invoice [number] from [Your Business] — Due [date]" 3. Write a brief body: greeting, amount due, due date, and payment instructions 4. Attach the PDF only — keep the email under 10 MB 5. Send from your business email address (not a personal Gmail if you have a domain) 6. BCC yourself for records or use read receipts if the client agrees
With InvoiceSonic Pro you can email invoices directly from the app with tracking. On the free plan, download the PDF and send from your email client.
