Hi,
To change the legal name/company name in QuickBooks Online, navigate to the company cog in the top right hand side of the screen and select 'Account and Settings' under 'Your Company'. This will bring up a new window. Click on the 'Company name' section where this will allow you to edit and change the details. Be sure to click 'Save' and then 'Done' to make sure all changes are reflected in the system going forward.
I hope this helps. If you have any other questions please do not hesitate to get in touch.
Kind Regards,
Emily
