At the start of the work on the CRM application, you need to assign your employees with appropriate roles in the system and add them the groups of the required selling directions. It needs to be done to provide them with access to the agent interface. The "out-of-the-box" solution includes five roles:
crm_certificate_manager– the employee responsible for the creatino of certification and emissions of the certificates.
crm_marketeer– the employee responsible for the marketing campaigns and lists management.
crm_admin– system administrator.
crm_sales– employee from the sales department responsible for the processing of leads and opportunities.
crm_manager– the leader of the sales department that can process the leads, work with opportunities and manage them.
