Chargebacks: How the Dispute Process Actually Works
A customer dispute through their card issuer feels similar to a refund from the outside, but the process behind it -- timelines, evidence requirements, and fees -- is different enough that treating the two the same can cost a merchant money and time they didn't need to lose.
Where a chargeback actually starts
A chargeback begins when a cardholder disputes a charge directly with their bank, not with the merchant. The bank provisionally reverses the funds and files a formal dispute case, which the merchant then has a limited window to respond to with evidence -- this is a fundamentally different process from a customer simply asking for a refund.
What counts as strong evidence
Signed delivery confirmation, a matching IP address and billing address, prior communication with the customer, or a signed receipt all strengthen a merchant's response. A generic "the customer used the product" statement without documentation rarely wins a dispute on its own.
The dispute is decided on documentation, not on who's actually right about what happened.
Reducing chargebacks before they happen
Clear billing descriptors (so a charge is recognizable on a statement), prompt customer service response to complaints, and clear refund/return policies stated at time of sale all reduce the odds a customer disputes instead of simply asking for a refund directly.
