How do I put the Australian business number on my invoices?

It's a pleasure to have you here in the Community space today. We'll provide details to help add your Australian Business Number to your invoices inside QuickBooks Online (QBO).

You'll want to ensure that the invoice template used for the invoices contains the ABN field. This way, when you create transactions for your customers, it'll reflect inside the invoice. We'll gladly write down the steps to get you going:

1. Access your QuickBooks Online company.
2. On the top right corner, click the Gear icon.
3. Select Custom form  Styles.
4. Locate the customer form style used for the invoices.
5. Click Edit below the Action column. 
6. In the Content section, tick the box beside the ABN field.
7. Once you're ready, click Done.

After adding the ABN field to the custom invoice template, you'll want to ensure the template is selected when creating the transaction. You can click the Print or Preview button to check and review the information added to the invoice.
