Hi there, @am-sandy.
In QuickBooks Online, there isn't a specific option for users to access view only. The capability of a user to view a specific class is unavailable.
As my colleague ReymondO mentioned, this will be submitted as feedback. Our engineers are always looking for ideas to consider on how to improve QuickBooks.
You can take a look at our blog site, where all added features and updates are listed.
I’m also adding a link that lists all our self-help articles. This page contains other resources that can help manage your business.
You can count me in if there's anything else you need. Have a great day!
