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.

What Happens If You Miss It

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.

Best Practices for Visa

Submit evidence within 5-7 days of receiving notification. Use digital evidence (emails, screenshots) whenever possible. Address the specific reason code directly and include a merchant declaration signed with your name and title.

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.

What Happens If You Miss It

Automatic loss similar to Visa. Mastercard rules against you without evidence review. Funds deducted and chargeback becomes final, contributing to your chargeback/fraud ratio.

Best Practices for Mastercard

Use the full 45-day window but submit by day 30 to be safe. Mastercard requires specific formatting. Provide evidence in the order matching their required fields. For recurring billing disputes, include all previous charges and customer consent proof.

American Express

Response Deadline: 20 Days

American Express has the strictest timeline: only 20 days from notification. This shorter window requires rapid response and evidence gathering.

Discover

Response Deadline: 30 Days

Discover allows 30 days, similar to Visa. Discover is stricter about evidence formatting than some networks, so clear organization is critical.

Best Practices for Discover
