You start with two: Sales Managers and Salespeople. Salespeople can only see their own leads and will report up to a Sales Manager. Sales Managers can view the leads for their entire team and re-assign if needed.
Any employee who has a sales role is using a Lead Management license.
To add or edit sales roles:
1. From the menu, click Settings --> Sales & Marketing Settings.
2. Go to the section Lead Management and click "Sales Roles."
3. To make a new Sales Role, click the Add Sales Role button
4. Name the sales role and click OK.
