Visa
Response Deadline: 30 Days
Visa cardholders have 120 days from the transaction date to file a chargeback. Once you receive a dispute notification, you have 30 days to submit your evidence response.

Automatic loss without evidence review. Funds are immediately deducted from your merchant account. The chargeback becomes permanent with no further appeals possible, and it counts against your chargeback ratio.

Mastercard
Response Deadline: 45 Days
Mastercard gives merchants the longest response window: 45 days from notification. This extended timeline gives merchants more time to compile comprehensive evidence.
