Good evening, @coastalkellie. 

Thanks for chiming back in on this thread. 

A company admin has access to every part of the QuickBooks account. They can do everything the primary admin can do, except edit or remove the primary admin's access.

You can find out all kinds of other details about users and what permissions they have through this link:

If you have any further questions, don't hesitate to ask. Have a great day!
