Hi there, 

Using QuickBooks Online is a great way to save time and effort in your business bookkeeping. I know how important it is to be able to change the language from English to French when running a Canadian business. I'd be happy to explain how easy QuickBooks makes this!

Here's what you'll do:

1. Click the Gear icon.

2. Select Account and Settings.

3. Click Company. 

4. Click the small pencil icon on the right side of the Language section. 

5. Select French.

6. Click Save. 

That's how easy it is! I hope this helps you get back on track. If you've got any other questions about this, just let me know. 

Have a great day.

It is now in the advanced options..
