Basically, with this privilege, they can edit existing items, but can’t add new ones unless they have full access.
Edit? Is posible to create a user with full access except to view (and edit of course) the personal and billing info?
The above post should explain it. But yes, to answer your question. I have my account plus 3 others. None of the other 3 have my billing information available to them. They have control over everything else except billing.
