Hello there, nicoschmidlin. We can switch the language to Francais so the interface will display in French. Let me guide you through the steps to make this change quick and easily.
Here's how:
- Go to the Gear icon.
- Under Your Company select Account and settings.

- Click the Advanced menu.
- In the Language column select Français.
- Click Save and Done.

Once done, you'll be able to use your QuickBooks account with the French interface seamlessly.

If you have any questions or need assistance with QuickBooks, don't hesitate to ask. I'm here to help.
