What should I do when receiving a Chargeback notification?

Introduction

When a merchant gets a chargeback notification, it’s basically the card issuer saying,
"Hey, your customer disputes this charge — prove it’s legit or we’ll take the money back." 

Here’s the step-by-step process:

Receiving the Chargeback Notification

• Where it comes from: Your acquiring bank or payment processor (not directly from Visa/Mastercard/Amex).
• What it contains:
  • Reason code (explains why the cardholder disputed — e.g., fraud, not as described, duplicate billing)
  • Deadline for responding (usually 7–14 days from notice)

  • Documentation requirements (proof you must submit)

     

Freeze or Withdraw Funds

• The disputed amount is temporarily removed from your merchant account or reserve.

• This is not a fine yet — just the issuer holding the funds until the case is resolved.

   

Investigate the Transaction

Gather all evidence related to the sale:

• Order details (date, amount, product/service description)
• Proof of delivery (tracking number, signed receipt)
• Customer communications (emails, chat logs)
• Proof of customer authorization (signed contract, recurring payment agreement)
• Refund/cancellation policies (and proof customer agreed to them)
  
   

Decide Whether to Fight or Accept

• Accept: If you know the claim is valid (e.g., you really made an error or the customer already got a refund).

• Fight (Representment): If you believe the charge is legitimate and you have strong evidence.

   

Submit Representment (If Fighting)

• Send to your processor/acquirer (they forward it to the card network and issuer).
• Include:
  • A chargeback rebuttal letter explaining why the transaction is valid.
  • Organized, clearly labelled supporting evidence.
• Deadline is critical — late submissions are automatically lost.
   

Wait for Issuer Review

• The card issuer reviews both sides and decides:
  • Win: Funds are returned to you.
  • Loss: Funds stay with the cardholder.
• Timeline: usually 30–90 days.
  
   

Possible Arbitration

If you lose and believe it’s unfair:

• Your acquirer can escalate to card network arbitration (Visa/Mastercard), but:
  • High fees ($250+)
  • Only for strong, clear-cut cases
     

Post-Case Actions

• If you lose:
  • Record the loss for accounting/tax purposes.
  • Review policies to prevent similar disputes.
• If you win:
  • Funds are restored.
  • Still track dispute frequency — high ratios can trigger merchant account termination.
