The differences between standard users, client users and collaborators as well as how to add standard users, client users and collaborators on the Grow, Deliver and Scale subscription plans
Standard user
Standard users are the primary user type in Teamwork.com for those who need access to the full range of available permissions. Each standard user occupies a paid seat in your Teamwork.com subscription, with the cost of each user varying depending on the subscription plan you have.
Client user
The purpose of client users is to enable you to bring clients into your projects where necessary, without incurring extra costs onto your subscription.
Client users can avail of the same range of project level permissions as standard users, but are restricted in some other aspects such as administrator privileges. They are also limited to joining a maximum of five active projects.
Client users are available on Deliver, Grow, and Scale subscriptions
Collaborator
Collaborator licenses are designed for bringing in third parties to your projects in a limited capacity. They can perform basic actions such as completing tasks assigned to them, adding comments & messages, or view files.
Like client users, collaborators are completely free on your subscription but their permissions are less expansive.
You can see how to invite or change a standard user license into a Client User or Collaborator by following the steps listed in our helpdocs.
