Users need a TurboSquid (or Shutterstock login) first, to be added as a user to a TurboSquid Corporate or Enterprise account. Please have them login using a Shutterstock login on TurboSquid or create a free TurboSquid user with their email address.
Once the user has been created, please contact enterprise@turbosquid.com to request the new user be added to your account. Please let us know if the user needs browse-only or purchasing access and if they require a spending limit. We can also assist with removing users, as needed.
