CiviCRM Community Forums (archive)

We want to implement CiviCRM to give access to 650+ clubs in the organization.
We need to find out the best way to set up CiviCRM that will allow us to do the following:

1-   create roles and permissions to “wall” off constituent data so Clubs can have access to only their constituent data. Waht option CiviCRM has?
   
2-    Multisite Drupal installation. Assure we have a correct set up that can support individual sites for multiple clubs interacting with CiviCRM.

3-    Functionality for accounting: Account coding from interaction on membership/donation page to internal reports for accounting purposes
Tag each donation/membership so we can see which club it came from.

4-    Customize information on the membership/donations pages the members will see, based on the URL they came from.
Each club will have links that will point to the main CiviCRM site: can we know which club each link came from and register the data into CiviCRM accordingly?

Is there a way to accomplish this within CiviCRM or do we need to customize it? In that case, how big of a customization are we talking about?

I will really apreciate your help,
