The system allows to process a chargeback and refunds for your credit card payments.
Chargeback vs. Refund. Which should I use?
If you want to cancel a credit card payment (only in Komet) you should process a Chargeback. This is done in cases of fraudulent transactions, duplicated billing, incorrect amount billing, bank processing errors.
On the contrary, if you want to process a refund to the customers' card (in case the item was not received by your customer, for instance, you should process the transaction as a CC Refund - Full).
Important
In order to return the whole amount of the transaction to the customer's card, refunds should be carried out on the same date as the payment date. On the contrary, the credit card processor may apply fees for the transaction.
