I have been working on a Magento E-commerce Project, my customer wants the Magento extension to be developed and I developed the same for my customer.
This extension, provide you the ability to categorize the customer groups and store view. You can create different store views for a different type of customers and then you can select the customer group and assign the different store views to them. you can choose multiple customer groups to for single store views. Once, you install this extension. It would be displayed like the below image. On this screen, you can see the store views and the relevant customer groups. After you click on any store view, you will be able to update the list of the customer groups.
This Magento Extension helps admins to set the different rules and assign those rules to different customer groups. It works well with the retail and wholesale customer categorization.
