When you first sign up for Cognito Forms, you create your first organization. You can have as many organizations as you like, and each organization has their own set of forms. Your organizations are separate from your account, which is the profile you create when you sign up. Learn more about managing your account profile.
Organizations can add additional users once the organization has been upgraded from the free Individual plan. Once you invite a user, all they have to do is look out for the email and accept the invitation. Learn more about adding or inviting users to your organizations.
