A chargeback is a processed credit card transaction that is reversed (charged back) to a merchant because the customer or customer's bank finds something wrong with the transaction. Transactions can be reversed due to several reasons such as authorization errors, processing errors, or disputes.

How do I get information on chargebacks?

The most efficient way to receive chargeback information is through the Business Track (formally known as ClientLine) Disputes Dashboard. Business Track offers chargeback information dating back 6 months, and provides merchants with the description, amount, issuer, and other transaction-related information. Through Business Track, merchants can immediately dispute chargebacks.

You can also receive chargeback details through mail or email but this method isn't recommended as letters can easily get lost in the mail or delayed and emails can be accidentally overlooked or deleted. You also run the risk of not having enough time to dispute the chargebacks due to the restricted timeframe for disputing charges.
