Thanks for dropping by, @garfield1.

Currently, the ability to set currency in the Products and Services is a product limitation in QuickBooks Online. When your QuickBooks account is purchased in your region, for example, Canada, the money you're going to receive is automatically converted to your home currency (Canadian dollar).

I'll share this article as your reference on how to add foreign suppliers with their corresponding currency.

Please let me know if you have more questions. I'm always here to help. Stay safe!
