Dispute resolution

Payment dispute resolution is the process a bank or card issuer runs when a customer challenges a transaction, from the initial complaint through investigation to a final decision on whether to refund the customer or raise a chargeback with the card scheme. In financial services, this means resolving a disputed payment, not settling a legal disagreement through arbitration or mediation.

The work sits in a bank's back office, handed off from the frontline team that first heard the complaint. It is not the chargeback itself, which is one possible outcome once a case is decided, and it is not fraud investigation: an unauthorised transaction the customer never made runs through a separate fraud workstream with different rules. Dispute resolution assumes the customer made or authorised the payment and is challenging the outcome.

How does the payment dispute resolution process work?

A payment dispute typically moves through five stages. Intake captures what happened directly from the customer, along with any evidence they already have. Classification maps the case to the correct card scheme reason code, such as goods not received or a duplicate charge. Evidence review checks what has been submitted against what the scheme requires, and flags any gaps.

Where evidence is missing, the case sits open until the customer supplies it, which is where most delay creeps in. Once the file is complete, a decision is made to accept the claim, in which case the issuer raises a chargeback with Visa or Mastercard, or reject it, in which case the customer is told why. The whole process typically runs somewhere between two days and two weeks, depending on how quickly evidence arrives and how large the case backlog is.

Frequently asked questions

How long does payment dispute resolution take?

It varies by issuer and case complexity, but most disputes take anywhere from a few days to several weeks. The evidence-gathering stage causes the widest swings: a case with complete evidence at intake can close in a day or two, while one that bounces back and forth with the customer for missing documents can stretch past a week.

What's the difference between a dispute and a chargeback?

A dispute is the whole process: the customer challenges a transaction, and the bank investigates it. A chargeback is one outcome of that process, the step where the issuer formally claws back funds from the merchant through the card scheme. Not every dispute ends in a chargeback; some are resolved without one.

Who handles payment dispute resolution?

Most banks and card issuers run it through a dedicated disputes or back-office team, separate from frontline customer service. The frontline agent who first hears the complaint typically hands the case to a specialist who applies scheme rules, reviews evidence, and makes the decision.

Can AI automate payment dispute resolution?

Yes. An AI agent can run intake, classification against scheme reason codes, evidence review, and customer follow-up, with a human approving the final decision. Gradient Labs' guide on how to automate disputes with AI sets out what that looks like end to end, including what a live deployment changes for turnaround time.
