Existing Customers List page: Quickly see which customers are linked to a parent customer. Any customers who show Parent after their name are linked to a parent customer.
Parent's Customer page: See which customers are related as child customers by viewing them in the Related Customers section. Click on any link to go to that child's Customer page.
