Avoiding Chargebacks
1. Q: What is a chargeback?
A chargeback is a transaction disputed by the cardholder or issuer. There are many reasons for chargebacks, but the most common are returned merchandise, terminated services, disputes, errors, or fraud.
Chargebacks are a costly part of accepting credit cards. However, merchants can minimize chargebacks at the time of sale by working to achieve maximum customer satisfaction and transaction accuracy.
Q2. What are the common practices that the merchant should do?
(1) Never let any customer operate your credit card terminal with the exception of keying in their PIN.
(2) If you get a “Decline” response, do not process any more sales on that particular card.
(3) Only use an authorization code which has been provided directly from your Merchant Processor.
(4) Never use the customer’s phone or phone number to call for transaction authorization.
Q3. How can I get a chargeback when I received an approval code for the transaction?
An authorization code simply verifies if the card is in good standing , has not been reported lost or stolen at the time of the transaction, and it has sufficient funds available for the amount of the transaction that you are attempting to process. An authorization code does not guarantee that you will not receive a chargeback.
Q4. How can I guarantee my transaction does not turn into a chargeback?
Fraud comes in all shapes and sizes. There is nothing that can be done to stop a dispute. However, most merchants can do a lot more to prevent chargebacks and minimize the risk exposure. For example, merchants can closely follow the transaction requirements and make sure to utilize all the available resources (AVS or Calling Code 10 Service.) Merchants may refuse to process any suspicious credit card transaction and request the customer provide a different form of payment.
Q5. How critical is the “Respond by date” from the chargeback or retrieval (copy) advice?
Whoever handles the response needs to pay special attention to the response deadline. Otherwise, a non-reversible chargeback will result in a financial lost. It is always recommended to respond to a chargeback or retrieval as quickly as possible to avoid many unexpected situations.
Q6. Why did the Merchant Processor debit my account without notifying me first?
When a chargeback is initiated by the card issuer, an automatic debit will occur against the Merchant Processor, and in turn that debit is passed to the merchant in accordance to Visa and MasterCard regulations.
However, the merchant can receive a conditional credit if they respond with sufficient information within the allotted timeframes to dispute the cardholder’s claims.
Q7. How long does a Card Issuing Bank have to bring up a chargeback?
A retrieval or chargeback can be requested by the Card Issuing Bank for up to 18 months after the transaction date. Therefore, it is crucial that you keep your transaction records accessible and legible for this time frame.
