Hi there, @Peter Hadden.

You can still use the same email address for different companies in QuickBooks by processing the change of an admin user. This user type can manage all other users in the company, along with their access rights.

I recommend contacting our customer service if you are using different emails or login IDs. As much as I'd like to look into this for you, account-related issues are handled by our live support.

To secure your privacy on this public page, we do not address these questions for safety purposes. We have dedicated customer support that can look over for your company ID and change your account information. 

Here's how to reach them:

1. Click the Help icon.
2. In the Help window, click the Contact Us button at the bottom.
3. Enter your concern and click Let's talk.
4. Choose a way to connect with us. Start messaging or Get a callback.

Please let me know if you have other concerns regarding your account. I'd be happy to assist you. Have a great day!
