Thanks for sharing your feedback about the tags in QuickBooks Online, Simon.
As of the moment, the tags feature only applies to invoices, expenses, and bills, but not to individual product or items.
With our goal to provide a user-friendly service, we would love to learn about your business needs. Please know that the changes in the program are released based on several factors, so we welcome product suggestions to help improve our programs. We're unable to provide the turnaround time on when new features are released in QuickBooks as they are handled by the Developers Team.
If you have any product suggestions to our developers about tags, send your request through these steps within your QuickBooks Online company file:
1. Go to the Gear :gear: icon, and select Feedback.
2. Enter your comments or product suggestions, then Next.
