Use the in-app help menu to invite your teammates to Salesforce Essentials.
1. Select Add Users.
2. Complete information about your new user and click Finish.
3. You’ll be able to see how many licenses are still available to assign on the bottom left corner of the pop up window.
When you create new users, you’ll need to assign a profile to each one: profiles define what users have access to in Salesforce and what they can do within the application.
The three types of profiles available in Salesforce Essentials are System Administrator, Standard User, and Read Only.
