🔄 The chargeback lifecycle

Definition and business impact

A chargeback (impayé carte in French CB terminology) is the mechanism by which the issuing bank sends an already settled transaction back to the acquiring bank. The process starts at the cardholder's request, though the issuer can also initiate it. Unlike a merchant refund, which the merchant decides on and executes itself, a chargeback reverses the settlement flow via the scheme (Visa, Mastercard, CB). The funds are taken back from the merchant before either side has been heard, and it is then up to the merchant to defend itself if it disagrees.

The vocabulary is standardized: dispute, retrieval request (a request for a copy of the sales record), first chargeback, representment or second presentment (the merchant's response), then pre-arbitration and finally arbitration (a ruling by the scheme). Each stage has its own initiator, deadline, and movement of funds. Confusing two of them means applying one stage's deadline or initiator to another, which can leave the merchant responding outside the deadline that actually applied.

The cycle at a glance

The cycle works like a four-player game of ping-pong: cardholder, issuer, acquirer, and merchant bat the same case back and forth from one stage to the next. The scheme carries messages between the two banks and, as a last resort, acts as judge. The vast majority of disputes end at the first or second exchange. Fewer than 2% of disputes reach arbitration, because arbitration fees ($500 and up) exceed the amount at stake in most orders.

The five stages, one by one

Fund flows: who debits whom

Each stage of the cycle triggers a real movement of funds between settlement accounts. Knowing who bears the risk at which point explains how each party behaves. An issuer that has already refunded its customer, as PSD2 requires in fraud cases, carries the loss until it raises the chargeback, the only way it can recover the money. It therefore has every incentive to raise it. The acquirer protects itself differently: it debits the merchant immediately and may even hold a reserve (rolling reserve) on high-risk sectors.

Fees at each stage

Each stage generates separate fees, charged to the merchant by its acquirer or PSP, and most of them are nonrefundable even if the merchant wins. Deciding whether to fight is therefore a calculation that weighs the amount at stake against the cost of handling the case. On a €12 order, spending €25 in fees and an hour of work for a 40% chance of winning costs more than the amount in dispute. The merchant then accepts a chargeback it considers unjustified.

A process that keeps evolving

The underlying trend is deflection, which resolves a dispute before it becomes a chargeback. It relies on data exchange (Order Insight, Consumer Clarity) or automated refunds (Rapid Dispute Resolution). The schemes are shortening deadlines and imposing financial penalties on dispute volumes. The formal chargeback is thus becoming a residual, costly last resort, reserved for disputes that deflection did not absorb upstream.
