I appreciate the details you shared to elaborate your concern, @Carl_A.
As of the moment, there's isn't an option to set up a user with Read-Only access in QuickBooks Desktop Pro.
In the meantime, you can consider setting up and manually choosing the access for a user in your company file. Thus, I've added this article that'll help you accomplish this: Setup Users and Restrictions.
But don't worry, I'll pass along your request to our product developers. This way. they'll know of your need for custom user's read-only access.
Additionally, I've included our Resource Center page so you'll be updated with all new enhancements in QuickBooks.
Lastly, you can always visit our Help Articles for QuickBooks Desktop in case you need some related article for your future tasks.
