Hi there, @HEMIN.
Yes, you're on the right track when assigning currency to your supplier.
The Multicurrency feature in QuickBooks Online helps you save transactions in foreign currencies. Knowing how multicurrency works in the system is essential to record your transactions. I'll be happy to share more on this.
The currency assigned to your Products and Services is your home currency and no foreign currencies can be displayed. This is because your inventory items are linked to Income and Expense accounts which always use your home currency in the system.
However, you can set up suppliers and customers in a foreign currency of your choice. This way, if you create a bill towards a USD supplier with your home currency being CAD. QuickBooks Online will display the total cost of the bill in both USD and CAD. To learn how to assign multicurrency to suppliers and customers, check out these articles.
If your transaction doesn't show both currencies despite everything being set-up, it could be due to a browser issue. Temporary internet files that accumulate in your browser can sometimes cause bugs in the software. To ensure your app or browser is running the program as designed, I recommend following the troubleshooting steps in this article: Clear cache and cookies to fix issues when using QuickBooks Online.
