What are Customer Types?
A Customer Type is a group defined to apply different pricing levels to different types of customers. For example, a customer who purchases at a wholesale price rate can be a Wholesale Customer Type.
Once the customer type logs into the site, their pricing will show throughout the site instead of the normal pricing.
