Hi there, allenfisherfronkcpas.
Thank you for posting here in QuickBooks Community. I'll share details and steps to ensure you'll be able to sign in to your account with one email address.
Usually, if you are using the same email when subscribing to both services, all these products will be under one Intuit account user ID. Since you want to update or use one email address when managing your different QuickBooks Online companies, you can send an invitation to your other account using the other account. For example, choose the email address you’d like to use for all your companies. We’ll call this email A. The email you no longer want to use is email B.
Here's how:
- Sign in to one of your QuickBooks Online companies that you access with email B.
- Invite email A to the company. Then, choose a user type and choose Company Admin if you want email A to be able to manage other users and company info. Please note that only admins can send invites.
- Go to your inbox for email A and select the invite link you received there. Email A can now access the company.
Once done, you can open this article to see additional information on how to finish the process: Sign in to multiple QuickBooks Online companies with one user ID.
If the issue persists, I suggest contacting our QuickBooks Online Support Team. As much as I want to check on this for you, account-related concerns are mainly managed by our live support. For security purposes, we do not handle account management questions to protect your data on this public page. We have dedicated customer service agents who can review your company ID and update your account credentials.
Lastly, you may refer to this article to see steps on how you can exchange between different companies quickly: Switch between company files in QuickBooks Online.
Let me know if there's anything that I can help in managing your account. I'm always here to help. Have a wonderful day!
