We can change the language from the browser, troy9.
For QuickBooks US the default language is English, and it also depends on the browser's language. We can change the language in browser settings instead. Just a heads up that once we change a language within the browser, it'll affect other opened sites. We can use a different browser instead to open QuickBooks or other websites.
Let me use the Google Chrome browser as an example:
At the upper-right of the opened browser, click the vertically lined dots.
Click Advanced and then Languages.
From the Language drop-down, click Add languages.
Select the language we'll want to use. Then, click Add.
Click the three vertical dots beside the language.
Check the Display Goggle Chrome in this language box.
I'll personally send this option to our engineers so we'll have the option to change languages within QuickBooks.
Reach out to me if you need anything else. Thanks!
