Thanks Earnie to your suggestion.
But I'm not sure to understand how can do it with Organic Group. I try to explain my requirements and if you can, please tell me how to do it with og.
I have 3 type of users: 1 - Shop 1 2 - Shop 2 3 - Shop 3
For every of this user types I have created a different roles. I don't know how to make different registrations form for every type, probably by using some external module? Otherwise a user after has been created, if has made "shop 1" registration, he should redirected to a creation of "group shop 1" and the same process for the other types.
I don't have much experience with og.
Thanks Nicola

Sounds like you have a need for drupal.org/project/og which allows assignment of a user as administrator of a group (shop) to allow other users (customer) access to the group (shop). Or perhaps something like drupal.org/project/domain and friends to assign a sub-domain to shop where customers are independent of other shops.
