A system and method for preventing multiple charges for a transaction in a payment system is presented. A payment system receives a payment operation request from the order system, and determines whether the payment operation is a duplication of a previous payment operation request. If so, the payment system retrieves stored financial transaction results and provides the financial transaction results to the order system. When the payment operation request is not a duplicate, the payment system contacts a payment provider to receive financial transaction results, which is passed to the order system and stored in a persistent data store.
