Theory Lesson 03
PAYMENTS / 5 MIN

When a payment is challenged.

Chargebacks, refunds and the work that happens after a sale.

Interactive explainer / Select a stage

A sale has an afterlife.

Explore the dispute route. This is a simplified teaching sequence; deadlines and later stages vary by scheme and provider.

The customer contacts the issuer.

The cardholder questions a transaction. Some enquiries can be resolved before a formal dispute. This is distinct from asking the merchant to issue a refund.

01

What is a chargeback?

In a card dispute, the cardholder challenges a payment through the issuer. A formal dispute can initiate a chargeback that reverses the payment through the card system. Not every dispute is an allegation of fraud.

02

A refund takes another route

A refund is initiated by the merchant through its payment provider. A chargeback follows the issuer and scheme dispute process. Treat the two as different workflows: a merchant should check the current dispute state before taking an action that could create duplicate reimbursement.

03

Evidence must answer the reason

A response about delivery may not answer an unauthorised-payment claim. Read the reason, deadline and eligible evidence in the provider’s process. A submission is not a guaranteed win. Time limits and stages depend on the scheme, provider and circumstances.

04

Learning goes beyond winning

Track what the outcome tells you about the underlying journey: confusing descriptors, fulfilment, cancellation, account security or payment misuse. Separate operational volumes from cohort-based analysis. Keep the customer’s claim and the eventual finding distinct.
