Welcome to the Community. QuickBooks offers a flexible platform that simplifies the way you manage your work. I'll be glad to share more info and help make sure you're on the right track with your work.
Since there isn't a way to convert the account currency in QuickBooks, I recommend looking into third-party apps that can assist you with the conversion. You can search for these apps on our app store desktop.apps.com. I recommend choosing an app that suits your business needs based on the app description and the reviews. In case you need further assistance with this, feel free to get in touch with our phone support team so they can share your screen and assist you further.
Otherwise, you're more than welcome to reach back to me in the comments below. I'm here to help you achieve your QuickBooks goals.
