What a Chargeback Is

  • A chargeback is a forced reversal a cardholder initiates through their bank to claw back a charge they dispute.
  • Unlike a refund you grant voluntarily, a chargeback is decided by the card networks and issuing bank, not by you.
  • The disputed amount is pulled from your account immediately, often before you have a chance to respond.
  • For subscription businesses, chargebacks frequently arrive on renewal charges the customer forgot they had authorized.
