Establishing best practices at the point of sale and ensuring that all staff adhere to them consistently is the greatest method to avoid chargebacks. In the event that the authorisation request was denied, do not finish the transaction.
If your request for authorization is denied, don't try again. Ask for a different payment option.
Call your authorisation center if you get a call message in response to an authorization request. The cardholder may be contacted by the operator to speak. Write the authorization code on the sales receipt after approval. Request a another method of payment from the cardholder if it is denied.
Credit receipts should be deposited as soon as feasible, ideally the same day as the credit transaction is created, with your merchant bank. Chargebacks for credit not issued may occur if credits are not processed promptly.
To sign, the cardholder must be present. On card-present transactions, the cardholder's signature is necessary. If the cardholder disputes authorizing or taking part in the transaction, failure to obtain the cardholder's signature could result in a chargeback for no signature.
Make sure that transactions are deposited and entered into the point-of-sale terminal just once per. Duplicate-transaction chargebacks can be caused by repeatedly entering the same transaction into a terminal, depositing the same transaction with more than one merchant bank, and depositing both the merchant copy and the bank copy of the sales receipt with your merchant bank.
Send the goods out before you deposit the money. Transactions shouldn't be deposited with your merchant bank until the associated goods have been sent. Customers may initiate chargebacks if they discover a transaction on their monthly credit card bill before they receive the ordered goods.
