What is a chargeback rebuttal letter?

In short

A chargeback rebuttal letter is the cover document a merchant sends with its evidence when contesting a chargeback, setting out in about a page why the dispute is invalid. The chargeback rebuttal letter summarises the transaction, answers the reason code point by point and lists the attached proof, so that the issuer's reviewer can follow the case quickly.

What a chargeback rebuttal letter contains

  • The case and transaction references, the date and the amount
  • The reason code and the claim it makes
  • A short account of the sale, in date order
  • Each piece of evidence, tied to the claim it answers
  • The request: reverse the chargeback, in full or in part

The evidence depends on the reason: delivery confirmation, usage logs for digital goods, the accepted terms and cancellation policy, the 3-D Secure result, or earlier undisputed orders from the same customer.

How a chargeback rebuttal letter is used

The merchant gives the letter and its files to its acquirer or PSP, which submits them to the issuer through the scheme's dispute system as part of the representment. Many providers have replaced the free-form letter with a structured form, because the scheme systems ask set questions for each reason code.

The issuer's reviewer decides on what is in the file, and the letter is the one place where the merchant speaks.

Why the rebuttal letter matters

A letter that argues the wrong point, runs long or arrives after the provider's deadline loses a case the evidence could have won. Templates per reason code, filled from order and delivery data, are what make contesting disputes at scale workable for a merchant or a platform.
