We are working on a new site that is a client portal. Each client could have different types of users but primarily an administrator and basic users.

We need to show content specific to each client and there will be about 200 client companies on the site. The client administrators will not need to be able to edit content as most content is going to be pulled from a data warehouse associated with the particular client. The administrator may add some documents in a document sharing section but not in other places.

Some parts of the site will be generic content but other parts will be information for the clients eyes only and no mixing of that content with other clients.

We are looking at roles and departments to handle this but it would be great to hear from someone who has built something similar. We know that getting the structure right in the beginning will make a big difference down the road.

Thanks for any ideas or advice on this.
