My previous post about painful payment reconciliation sparked lots of interesting discussions. One of the readers shared more problems we may face when working with intermediary payment processors in the trenches and a potential solution: 1. Foreign Currency Problem: When you operate a store globally, you will come across this problem quite frequently. To go back to the example from Paypal - if the transaction happens in a currency different from the standard currency of Paypal, this will create another layer, where the transaction is first received in that currency and exchanged to whatever currency your Paypal is using. There needs to be a reliable way to reconcile that currency exchange transaction. It certainly does not help that every payment provider handles this differently.
