The overall chargeback process is depicted in this Chargeback process flow diagram. A chargeback is money returned to a debit or credit card after a customer disputes the transaction or returns the purchased item. The merchant or the cardholder's issuing bank can initiate the chargeback process. Typically, a chargeback begins with the cardholder disputing a charge. If the bank creates a chargeback, the merchant can fight it or accept it. If they contest it, the bank looks over the evidence and decides which can be appealed if necessary. This Chargeback process flow diagram also depicts the various steps that occur during this process.
