How do i change the date format which is currently showing as US mm/dd/yy to the Australian format dd/mm/yy?

Hi there, Stefanie.

I can assist you with changing the date format in QuickBooks Online (QBO) to manage your data in the Australian format. 

Here's how you can do it:

1. Go to the Gear icon at the top.
2. Select Accounts and Settings.
3. In the left menu, choose Advanced.
4. Scroll down to the bottom, then select Other preferences.
5. Click the pencil icon beside the Date format.
6. On the Date format drop-down arrow, select dd/MM/yyyy.
7. Select Save, then Done.

If you want to add a new user to your QBO account, you can check out this article on how to add and manage users in QuickBooks Online.

If you have any other concerns about setting up your QuickBooks Online account, please let me know. I'm always here to help. Have a great day!
