Hello mdandreaqbo,
It's vital you're able to set up vendors with multiple currencies using QuickBooks and I'll be glad to assist. QuickBooks Online is a dynamic program that assists you with getting your work done faster. I'll be glad to steer you on the right path with this.
The program allows you to add suppliers using different currencies and based on what you've described, I recommend double-checking to see if you've got multicurrency turned on. This article here does a great job of explaining more about using multi-currency on your account. To add a new supplier in a different currency, click on Expenses from the left navigation menu > Suppliers > New supplier > from here you can enter the necessary details including the currency as well. Make sure your info saves properly.
Give this a try and let me know how you make out, I'll be one message away in case you need further assistance. Otherwise, I wish you a great rest of the day.
