Within Teamwork projects, when adding a user to your site, you will be prompted to add them to a company.
The owner company will be selected by default, however you can choose to add a new external company or choose an existing one.
Note: A user can only be part of one company at a time.
To add a new user, or update an existing user's details, go to the People area near the top left of your site:
