Chargebacks can be complex, but acting quickly and following the right steps can help you resolve disputes successfully. Here's an easy-to-follow overview of the Mastercard chargeback process and what you need to do at each stage:
1. Notification of Chargeback (NoC)
- What Happens: You’re notified of a chargeback. 
- Your Action: Submit defense documents to contest or accept the chargeback. 
- Key Point: The chargeback amount will usually be debited from your account a few days after notification. 
2. First Chargeback
- What Happens: The disputed amount is withdrawn from your account. 
- Your Action: Upload defense documents within 40 days, or accept the chargeback. 
- Key Point: If you don’t act in time, the process ends here. 
3. Information Supplied
- What Happens: PbN submits your defense documents to Mastercard. 
- Key Point: Once submitted, you cannot make any changes to the documents. 
4. Chargeback Reversed
- What Happens: The disputed amount is temporarily credited back to your account while your defense is reviewed. 
- Key Point: If your defense is accepted, the chargeback is resolved in your favor. 
5. Pre-Arbitration
- What Happens: If your defense is rejected, the issuer files a Pre-Arbitration case within 45 days of your defense submission. 
- Key Point: After this stage, there’s no option for arbitration. 
6. Pre-Arbitration Outcome
- If Won: Your defense is accepted, and the chargeback is resolved in your favor. 
- If Lost: A second chargeback is processed, and the dispute process ends. 
7. Second Chargeback
- What Happens: If your defense is declined, a second chargeback is finalized. 
- Key Point: This is the final step, with no further options for resolution through Mastercard.
