Contracts allow you to associate a particular catalog, list price, and other terms with a specific account. Note that each account can be associated with only one contract.
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.
