Sales Tier Levels determine what level of access an Administrator has to view and edit Sales Persons assigned to clients.
There are three choices for Sales Tier: tier 1, tier 2, and none.
Tier 1: This gives the administrator complete access to view and change sales commission rates for any client, as well as to assign any salesperson to a new client.
Tier 2: This is the same as tier 1 access, except that the administrator cannot add himself/herself as a salesperson for a new client. He/she can add any other salesperson, or change commission rates for any salesperson (including himself/herself).
None: The administrator cannot see the salesperson and commission fields on any client, and thus cannot add, remove, or change salespeople.
