Customer Groups allow you to associate certain customers in order to give them special pricing through Price Sets or undertake other group actions, such as assigning Tags or special security levels on the site.
To create a Customer Group, select Store Manager > Customers, and then select the Customer Groups tab.
The left part of the Customer Groups tabs shows both Active and Deactivated Customer Groups.
To add a group right-click in the Active tab area and select Add Group.
If defined that way, Tags might allow you to assign a customer type (financial, healthcare, high tech, non-profit), geography (NA, EMEA, etc.) or an audience segment (frequent shoppers, new shoppers, potential shoppers)..
Developers can use security levels to manage the information that customers see. See the iAPPS Developer Documentation for more information.
To edit a group right-click a group in the Active tab area and select Edit Group. Edit details as noted in last section.
