What is the "Interface group" subscription?

Group Interface is another type of subscription, different from autobizMarket in that it allows you to analyze all your group's stock at a glance. This subscription is used by managers in general. It gives you a one-click view of your POS to manage your sites. Apart from this feature, the Group Interface subscription gives you the same functionalities as a classic autobizMarket subscription (Quotes, Analysis, including 100 quotes + ... ).
