Systems and methods consistent with the present invention may be used as part of determining whether to chargeback a purchase transaction amount to a merchant. To this end, the system may heuristically analyze purchase transaction data to determine which transactions to analyze for chargeback processing. For instance, the system may identify purchase transactions that are likely to qualify for a chargeback. For the identified purchase transactions, the system may then determine an expected value for each transaction in terms of received revenue from chargeback processing and the costs for performing a chargeback. Using the expected values for this transaction data, the system may then prioritize which purchase transactions to review for chargeback to a respective merchant.
