My refund transaction flows to a different account in contrast to the account that I have opted for in the NetSuite account mapping, why?
Solution
When the transaction that is being synced is of the type “Chargeback” that is, the payment method is displayed as “Chargeback”, it does not sync as per how a usual refund transaction sync.
The chargeback would be considered an offline payment and will sync as per the offline payment's account mapping.
Hence, update the mapping as per your preference if you wish to have the account (that is used for online transactions) to be synced for chargeback transactions as well.
