Hello there, Evbates,
Is there an error message when you accept the invitation to access the 2nd company? If so, please update this post or attach a screenshot so I can check what's going in your end.
In the meantime, you can enter the login credentials used during the invites. Then, merge them later once you're able to access the 2nd company.
If you're seeing a message, like "email address already in use", this means you have already an existing Intuit account. You can click the Sign in link instead, then enter your current user ID and password. This will help ensure you only have one login info.
You can also contact our QuickBooks Online Support Team so they can do screen-sharing with you. Then, walk you through the steps on how to create one user ID for all your QuickBooks companies.
Here's how to contact them:
- Sign in to your QuickBooks Online company.
- Go to Help (?).
- Select Contact Us.
- Enter your concern, then select Let's talk.
- Choose a way to connect with us:
- Start a chat with a support expert.
- Get a callback from the next available expert.
I'll keep this post while waiting for your response. Thank you and stay safe!
