What Every Merchant Should Know about MasterCard Chargebacks

A chargeback is a process through which a card issuer charges the whole transaction amount or part of it back to the processing bank, in effect reversing the associated sales transaction. This reversal may be prompted by a number of reasons, which could cause the issuer to determine that the transaction is not valid.

Each credit card association (i.e. Visa or MasterCard) and company (e.g. American Express or Discover) has established its own rules regulating the chargeback process and in this article I will offer a cursory overview of the way MasterCard has done it.

Chargebacks Reasons

MasterCard chargebacks are grouped into five major categories:

  • Authorization.
  • Fraud.
  • Cardholder disputes.
  • Retrieval request and documentation required.
  • Processing or procedural errors.

Chargebacks are typically the result of a customer dispute or an error in the transaction’s dollar amount.

Chargeback Process

After a sales transaction is first presented for payment to the issuer by the processor, the former may determine that it is invalid and may then return the transaction to the processor as a chargeback for possible remedy. Following the first presentment, the chargeback life cycle may include:

  • First chargeback (submitted by the issuer).
  • If necessary, a second presentment (submitted by the processor).
  • If necessary, an arbitration chargeback (submitted by the issuer).

The issuer must initiate the first chargeback within a time frame that is specific (and determined by MasterCard) for the applicable reason code. If the issuer and processor do not resolve the case within the above three cycles, they must send it to MasterCard for arbitration. Additionally, if an issuer needs a copy of the sales receipt, the retrieval process is made up of two stages — Retrieval Request and Retrieval Fulfillment. The retrieval process may also include an Image Review.

Retrieval Requests and Retrieval Fulfillment

The issuer can request the transaction receipt from the processor if there is any question about the disputed sale that the original document or fax may help resolve. To complete this cycle, the processor either fulfills the issuer’s request or sends back a message to the effect that it is unable to honor it.

The Takeaway

It is essential that, whenever you receive a chargeback, you first evaluate its validity and act accordingly. If the chargeback is valid, do not waste time disputing it, but just accept it and move on. If the chargeback is not valid, quickly provide a legible copy of the associated transaction’s receipt to your processor for a second presentment (re-presentment). Keep in mind that, if your processor receives the transaction document past the applicable time frame, you will automatically lose the case, regardless of whether the chargeback is valid or not.
