Hi, I can't see my ABN on printed invoice. Please help. Customers can't see on invoice

You may check the ABN (Australian Business Number) field using the Custom form styles feature in the QuickBooks Settings. Here's how to enable this field:

1. Go to the Settings and select Custom form styles.
2. Click on the New style button and choose Invoice.
3. Select the Content tab and click on the header section of the sample preview to see the details in it.
4. In the Header section, check the box with ABN.
5. Select Done. This is how it looks like:
