Users Overview
You can add as many users as you require to run your businesses and you are charged a set fee per month per user.
To add users go to "Setup > Users" and click on the + Add User button.
If you add a user and set "Administrator" to yes, that user will have access to everything.
If you are setting up a non-administrator you can choose which businesses that user has access to.
Avatars
By default, the system uses Gravatars but you can override that by uploading an avatar manually.
