I spoke to someone in support and have been told to add the business name to my address in my account. This is how I was told to do it
First address box— Buisness Name: XYC
Second addres box — first line of address etc.
Then the rest is just as you would normally do it.
They say they can't edit past fee invoices but I just checked a couple and the business name was there so it looks like its fixed … maybe
Please note that you can enter your company name in the legal name field on the TAx Info page if you'd like your company name to be displayed on your invoices. Let me know if you're referring to another aspect of the invoices available on your end.
