Other questions

I appreciate you for posting your concern here today, @Patw2. I'm here to provide some insights about the tag feature in the new invoice layout format of QuickBooks Online (QBO). 

You can refer to the steps provided by my peer, KurtKyle_M, above if you use the new invoice layout in your QBO. Just click the Try the new invoices.

At any point, you can choose to have the old or new experience. To prevent you from losing your work, QuickBooks keeps all the data from your past estimates and invoices. 

For additional details on the new invoice experience in QBO, see this article: See what’s new with estimates and invoices in QuickBooks Online.

You can also refer to this guide to learn how to customize invoices, estimates, and sales receipts in QuickBooks Online. 

Don't hesitate to reply anytime if you still have questions or concerns about managing invoices. I am always here to help. Take care, and have a great day ahead.
