In one embodiment, a method for conducting a model-based chargeback representment includes acquiring, by a transaction processing system, a record of a chargeback asserted by a customer against a merchant for a transaction. The method includes determining, by the transaction processing system and using a chargeback representment model, a confidence of asserting chargeback representment for the chargeback, wherein the chargeback representment model is trained to predict the success of a chargeback representment based on analyzing the context and characteristics of a chargeback. The method includes facilitating, by the transaction processing system, chargeback representment for the chargeback for the transaction. The method includes receiving, by the transaction processing system, results of the chargeback representment for the chargeback. The method includes providing, by the transaction processing system, the results of the chargeback representment for the chargeback to the merchant.
