Can you escalate this issue to your development team? I believe this should be an enhancement request. The system should have a way to block licenses to be added to the account and only administrators should have the power to create new users. We use other products here, none of them give the users the power to grab a license on their own.

I agree the currently design enhances security by only allowing managed users on the account, this is perfect, but at the same time is causes issues with customers that have a limited number of licenses and have to work with a strict budget. Box is forcing account creation without an approval, it does not seem right and I don’t think I’m the only one that is pointing this out.
