It's nice to see you here in the Community. I can help you change your QBO account linked to your clients.
If you're using QuickBooks Online Accountant, then yes you can definitely change your QBO Accountant account that is linked to your respective clients, and I'm happy to show you how:
1. Go to Gear icon, then pick You Account under You Company. 2. Select Remove existing clients. 3. Check the clients you wish to remove, then choose Remove Clients. 4. Read the notification, then click Continue.
That should do it! Please let me know how it goes or if you're referring to something else by leaving a comment. I'd be glad to answer should you have additional questions. Wishing you and your business continued success.
