How the process runs
The cardholder contacts the issuing bank and disputes a transaction. The bank provisionally credits them and passes the claim down through the card network to the acquirer, which debits the merchant.
The merchant can contest it, a process called representment, by supplying evidence: delivery confirmation, order records, communication with the customer, proof the service was rendered. The issuer reviews and decides. Cases can escalate further, and each escalation costs more.
Dispute windows are long. Depending on the reason code and the network, a cardholder can raise a claim months after the transaction, and in certain categories much longer than that.
What it actually costs
Far more than the disputed amount, which is why merchants who have never had one underestimate it.
The transaction value
, returned to the cardholder.
A chargeback fee
, charged by the acquirer regardless of who wins. Typical range runs from fifteen to a hundred dollars.
The goods or service
, already delivered and unrecoverable.
Staff time
assembling evidence, which for a small merchant is the largest hidden line.
The ratio
Card networks run monitoring programmes, and a merchant whose chargeback rate crosses roughly one percent of transactions enters one, with escalating fines and, eventually, the loss of the account. In high-risk categories this is the mechanism that ends merchant relationships.
Chargeback or refund
A refund is the merchant sending money back voluntarily. It costs the transaction value and possibly the processing fee, and it counts against nothing.
A chargeback is the bank taking money back involuntarily. It costs everything listed above and counts against the ratio.
This is why experienced merchants refund quickly when a complaint looks legitimate. A refund at fifty dollars is cheaper than a chargeback at fifty dollars, several times over.
There is also friendly fraud, where a customer disputes a purchase they made and received. A crypto payment gateway has no equivalent mechanism at all. It is hard to contest and it counts the same.
Why crypto payments have no chargebacks
A confirmed blockchain transaction cannot be reversed. No bank sits in the middle with the authority to pull funds back, and the network has no mechanism to undo a transfer once it is in a block.
A merchant who wants to return money sends a new transaction in the opposite direction. That is a refund, entirely under the merchant’s control, and it happens because the merchant decided it should.
For high-risk categories this removes the single largest source of unpredictable loss, and it is the reason a card acquirer charges 5 to 10 percent where a crypto gateway charges 0,4 to 1.
