Hi, thanks for link, yes, manager can see only project stats like words translated and so on, everything subscription related is personal, and managed only user by user in Crowdin.
In Enterprise version there are some admins, and staff like that, so they can manage organization like owner, but in Crowdin one (1) account can be a manager in project 1, owner with own subscription on project 2, and translator in project 3.
The username that is written above your project name (top left corner of project’s ui) is owner + owner is shown in project description, only he/she can see exactly what the plan you’re using.
