Your wp2print site contains 2 types of store: Public stores, which will be used by the general public, and Private stores, which will be used by your large accounts. Private store are password-protected "mini-stores" that is only accessible by certain users or groups of users. They will have access to different products, a different site layout and multiple ways to pay for the products. The products you place into private stores are not visible to the general public nor are they visible to members of other private stores.
In order to create a private store, you must create a customer group, place customers into that customer group, and set a category or products to be visible only to that customer group. This section of the help will outline these steps, as well as provide information on various options available when creating customer groups and private stores.
The video below illustrates some of the changes customers see when they login as a private store customer:
