System and method for evaluating requests

Abstract:

The evaluation system provides a real-time mechanism for auditing purchase request transactions prior to the purchase being completed in order to determine if one or more audit parameters are violated and the transaction should not be completed. An electronic product request can be received from a merchant of the product. The request can identify at least the merchant, the party, and the product requested for purchase. One or more business rules and auditing parameters for auditing the request can be identified based on the identity of the merchant. The contents of the request can then be audited to determine if the request satisfies the audit parameters. The contents of the request can also be used to identify historical transactions for the party, which can be used to determine if the current request violates one or more of the audit parameters.
