We are moving from one accountant to another. The former was hosting our QBO. He cancelled but was still listed as our accountant. Now I can't delete him and add new.

Good morning, @bjohnson1. 

It's great to see you back in the Community! Let's work together to figure out why you're unable to delete your old accountant and add a new one in your QuickBooks Online account. 

To clarify, I'm going to gather some additional information from you: 

• What message are you receiving when trying to delete your accountant? (Screenshots are great as well if you have them) 
• Were you on their billing or do you have your own billing for QBO?  

In the meantime, I recommend reviewing this article about billing with accountants: Transfer clients to your wholesale discount plan in QuickBooks Online. 

I'll be waiting for your response so we can determine the best solution for your business!
