Hi Bill,
Sorry for the delay. Our multicurrency section is more oriented to orders. For example, if you use a multicurrency plugin on your site and some customer purchases a product in a currency different than the shop base, our multicurrency section will use the values to convert the cost and profit values from the order to the shop base currency.
Our plugin expects the product costs to be registered with the base shop currency.
Do you know if your products from other countries have some meta indicating the cost currency? If that’s the case, we could try to create a new option on our “Import” tool and convert the cost values automatically to the base shop currency based on the product currencies. Do you think it would work for you? Or do you have some other suggestion?
