Chargeback
A chargeback is a forced reversal of a card payment, initiated by the cardholder’s bank rather than by the merchant. The money is taken back out of the merchant’s account under the card scheme’s dispute rules, whether or not the merchant agrees.
Also called: dispute · ACH return
A chargeback starts when a cardholder tells their issuer that a payment was not authorized, not delivered, or not what was described. The issuer reverses the payment under the scheme’s dispute rules and claims the funds back from the acquirer, which in turn debits the merchant. The merchant can contest it with evidence, and a case can run through further rounds, but at no stage does the merchant control the outcome.
Why it matters
The lost sale is only part of the cost. Each dispute carries a fee on top of the refunded amount, and the schemes monitor the ratio of disputes to transactions at merchant level. Sustained high ratios pull a merchant into remediation programs, then into higher pricing, larger rolling reserves or termination — which is the practical meaning of being treated as a high-risk merchant. Acquirers hold a reserve account precisely because disputes can arrive months after the sale was settled.
Thresholds, time limits and evidence requirements are set by each scheme’s own rules and are revised from time to time, so a ratio or a deadline quoted in an article is not a reliable basis for planning.
In practice
A chargeback is decided by the cardholder’s bank under card scheme rules; the merchant can present evidence but cannot veto the reversal. ACH has a parallel mechanism in the return, which reverses a bank debit on different timeframes and under different rules — so a card dispute playbook does not transfer to ACH.
Example
A cardholder buys furniture in March that never arrives. In June they call their bank and dispute the charge. The issuer reverses the payment and recovers it from the acquirer, which debits the merchant’s settlement account for the sale amount plus a dispute fee. The merchant may later win the case on delivery evidence, but the funds are gone in the meantime.

- AcquirerAn acquirer is the institution that contracts with a merchant to accept card payments, submits those transactions into the card schemes, settles the merchant’s proceeds, and carries the acquiring-side financial exposure — including the cost of chargebacks the merchant cannot fund itself.
- Reserve AccountA reserve account holds funds a bank, acquirer or partner keeps back against future chargebacks, refunds or unsettled exposure, released on an agreed schedule. The money is economically yours, but it is out of your hands while it is held.
- High-Risk MerchantA high-risk merchant is a business an acquirer classifies as elevated risk because of its dispute rate, its regulatory exposure or its reputation — gambling, adult content, crypto, nutraceuticals and retail forex are the usual examples. The label is the acquirer’s, not a regulator’s.
- IssuerThe issuer is the bank or licensed institution that gives a cardholder their card, holds the account the card draws on, decides whether each transaction is approved, and pays the acquirer for the ones it authorizes. It sits on the cardholder’s side of every card payment.
