Contracts let you associate a particular catalog, price group, and other terms with each account. Contracts can be created within the context of a published site. You can associate an account with more than one contract. This allows you to run multiple sites from a single Commerce Cloud instance. Note that a contact cannot access a site until a contract has been associated with the contact’s account. For information on working with multiple sites, refer to Run Multiple Stores from One Commerce Cloud Instance.

Once you have defined a contract for an account by associating the account with a catalog and a price group, you can change the catalog or price group but you cannot leave either field blank. To prevent a contract from being used, deactivate the account so that all transactions with the account stop. See Deactivate an account for more information.

Commerce Cloud administrators create and manage contracts in the Commerce Cloud administration interface. Delegated administrators cannot perform these tasks.
