How to Create an Invoice

Creating an invoice means turning the work you've done into a clear, professional payment request. You can use a Word or Excel template, accounting software, or a free online generator — the fastest option for most small businesses.

To create an invoice from scratch:

Open a blank template and add your branding — logo, business name, ABN, and contact details
Number the invoice sequentially (e.g. INV-001, INV-002) and add the issue date
Enter your client's full name or business name and billing address
List each product or service on its own line with description, quantity, rate, and amount
Total the line items, add GST or other taxes, and show the grand total
Specify payment terms, due date, and payment methods
Save as a PDF before sending — PDFs lock in formatting and look professional

If you're invoicing the same client repeatedly, save a template with their details pre-filled to save time. InvoiceSonic lets you create unlimited invoices for free, with automatic numbering, GST calculations, and PDF downloads.
