Hi there, @caii.
Welcome to the Community. I can share some details about the multi-currency feature in QuickBooks Deskop.
You can add foreign currency customers, vendors, and accounts but there's no option yet which you can add 2 different currency per product. This is actually a great idea, and I can help you pass along this to our product team.
