I want To change the langage in french

Hi there, 

QuickBooks Online is an awesome tool for any small business owner. It's important that you're able to use the account in your preferred language, and changing it is simple and straightforward. I'd be happy to explain the steps you'll follow to change the language, as well as what you should expect once the change has been made. 

To change the language, follow these steps:

1. Click the Gear icon at the top right of the page.
2. Choose Account and Settings.
3. Go to the Advanced tab in the left menu.
4. Find the Language section and click to edit it.
5. Choose the language you want.
6. Hit Save to make the change.
7. Click Done to exit out of Account and Settings.

Once you've made the change, you may notice that some features appear in English and others in French. This is an abnormal issue that our engineers are aware of, and we're working on ways to fix it.

I hope this helps get you back on track. 

Cheers.
