I'm happy to see you're looking the perfect your invoices. Having professional sales forms is important for businesses of all sizes, and the customization options available in QuickBooks Online are designed to help you create styles that include the information you need. Since the fields are already enabled, I'm confident we'll have no problem getting them to appear on PDFs.
If you're able to see the Due date field, you've already completed most of the set up. It's just a few easy steps to display it on your invoice.
Click on the Gear icon and select Custom Form Styles.
Select Edit for the style you use for your invoices.
Go to the Content tab and select the top of the preview.
Make sure Due date or expiration date is checked then click Done.
Now all your invoice PDFs should display this information. Let me know if this works!
