National merchant dispute guidance
How Long Does a Merchant Have to Respond to a Chargeback?
A merchant does not have one universal response period for every chargeback. The deadline depends on the payment network, dispute stage, acquirer or processor workflow, and case details. Stripe's current merchant guidance describes a usual window of 7 to 21 days depending on the card network, but the date displayed in the merchant's actual dispute notice or provider portal is the deadline to follow.
Direct answer
Use the case-specific due date, not a generic countdown
Provider documentation may offer a typical range, but a merchant should begin with the exact deadline shown for the live dispute. Card-network rules include multiple stages and condition-specific time frames, and a provider may set an earlier operational cutoff so it can review and transmit a response.
Why deadlines vary
Four details shape the response window
Payment network
Each network operates its own dispute rules and stages. A time period used for one network should not be copied to another without confirming the case.
Dispute stage
An inquiry, initial chargeback, pre-arbitration step, or other case status can have a different action and deadline. Confirm what response the notice actually requests.
Provider cutoff
Acquirers, processors, and payment platforms receive network messages and submit merchant evidence. Their portal deadline is often the practical merchant cutoff.
Case eligibility
Some disputes cannot be challenged or may already be past due. The case record should show whether the merchant can accept, respond, or take another available action.
First-day workflow
What to do when a dispute arrives
Capture the notice
Record the case ID, disputed transaction, reason or condition, amount, network, response options, due date, and the time zone associated with the cutoff. Save the original notification.
Assign an owner
Route the case to a person who can retrieve order, fulfillment, refund, policy, and customer-communication records. Name a backup so absences do not consume the response window.
Choose accept or challenge
Review the claim and available records early. If the merchant challenges it, build a concise response that addresses the stated reason rather than uploading every document available.
Submit before the final day
Allow time for file conversion, portal errors, internal approval, and provider questions. Confirm that the case status changes or that a submission receipt is available.
Deadline sources
Where to verify the controlling date
Provider dispute portal
Open the individual case and look for the evidence due date, respond-by date, or countdown. Check whether the displayed value includes a time of day and time zone.
Dispute notice
Compare the portal with the email, letter, or downloadable notice. Keep the notice because it documents what the merchant received and when.
Provider API
For automated workflows, monitor the provider's due-date and status fields. Alert on new cases and approaching deadlines, and test for missed webhook deliveries.
Acquirer or processor support
Escalate discrepancies promptly. Ask which stage applies, which date controls, whether a response is permitted, and how successful submission will be confirmed.
Operational controls
Build a workflow that protects short windows
Centralize notifications
Maintain current dispute contacts and send portal, email, and webhook alerts to a monitored queue rather than one person's inbox.
Keep evidence findable
Link transactions to order confirmations, delivery or service records, refund activity, policies accepted at purchase, and relevant customer communications.
Set internal targets
Create review and approval checkpoints ahead of the external cutoff. Use escalation rules for cases that lack an owner or required records.
Track completion
Record whether the case was accepted or challenged, when the response was submitted, what evidence was included, and the confirmation supplied by the provider.

Common questions
Merchant response-deadline FAQ
Do merchants always receive 7 to 21 days?
No. That is a typical range in Stripe's current card-dispute guidance, not a universal entitlement. Use the deadline shown for the merchant's actual case.
Is the network deadline the same as the provider deadline?
Not necessarily. A provider may require evidence earlier so it can process and transmit the response. Follow the provider's live case instructions.
What happens if the deadline is missed?
The merchant can lose the opportunity to challenge the dispute through that response stage. Confirm the status with the provider rather than assuming a late upload will be accepted.
Can evidence be edited after submission?
Provider rules vary. Stripe's current guidance says its merchant response is final after submission, so merchants should review the complete packet before sending it.
