FAQs

How long does a merchant have to respond to a chargeback?

Response windows are short and strictly enforced: typically 7–30 days from the chargeback notification depending on reason code and card network. Missing the deadline results in automatic loss of the dispute regardless of evidence. Merchants should have processes to immediately route chargeback notifications to the appropriate team.

What evidence is most effective in winning a chargeback dispute?

Compelling evidence varies by reason code: for 'item not received,' use tracking confirmation with signature; for 'subscription cancelled,' show the cancellation date was after the charge; for 'fraud,' show device fingerprint, IP address, and 3DS authentication success. Matching billing and shipping addresses, AVS matches, and customer communications are also valuable.

What is chargeback fraud vs. friendly fraud?

True chargeback fraud involves actual unauthorized use of a stolen card. Friendly fraud (also called first-party fraud) occurs when a legitimate cardholder disputes a transaction they authorized — perhaps forgetting a subscription, wanting a free return, or deliberately exploiting the system. Friendly fraud now exceeds true fraud in most ecommerce segments and is much harder to combat.

A chargeback is a forced reversal of a credit or debit card transaction initiated by the cardholder through their issuing bank, in which the bank reclaims the funds from the merchant. It was designed as a consumer protection mechanism but has evolved into a significant business risk management challenge for merchants of all sizes.

The chargeback process: (1) Customer disputes a charge with their issuing bank, citing a reason (fraud, item not received, not as described, subscription cancelled but still charged, etc.); (2) The issuing bank provisionally credits the customer and initiates a chargeback claim; (3) The merchant's acquiring bank notifies the merchant and requests documentation; (4) Merchant submits rebuttal evidence (proof of delivery, signed authorization, etc.); (5) The issuing bank rules for either the customer or merchant based on evidence; (6) Further escalation to card network arbitration is possible.

Each card network (Visa, Mastercard) has detailed reason code taxonomies and strict documentation requirements. Visa's dispute reason codes include: 10.x (fraud), 11.x (authorization), 12.x (processing errors), 13.x (consumer disputes). Mastercard has its own parallel system. Understanding reason codes is essential for building an effective chargeback response strategy.

Chargebacks are costly: the disputed transaction amount is reversed plus a $15–$100 chargeback fee per dispute. If a merchant's chargeback rate exceeds 1% (Visa threshold) or 1.5% (Mastercard threshold), they risk being placed in monitoring programs with additional fees or ultimately losing card acceptance privileges.

Friendly fraud — where customers dispute legitimate charges they authorized — is a growing problem, estimated to account for 40–80% of chargebacks. Merchants combat this with detailed transaction records, clear refund policies, delivery confirmation, and specialized chargeback management tools.
