Can't login from company invite

I hope your day is going well, Adam Forist.

I appreciate you for letting me know in advance about the troubleshooting steps you've performed already.

Once the invitation is accepted, you should be able to log in from that QuickBooks company. What I can recommend is to reach out to the administrator and double-check if you're still added as one of their users.

It could be that they have accidentally remove you as a user to access their QuickBooks account. That's you're getting that specific error. Note: This is only to verify the situation.

To fix this issue, you can ask them to remove your access and re-invite you to refresh the connection. They can follow these steps to add you again: 

1. Go to the Gear (Settings) icon in the top right-hand corner. 

2. Under the Your Company column, choose Manage Users. 

3. Press Add user. 

4. Pick the user type you want for them. 

5. The admin will enter your name and email address .

6. Once done, click Save. 
   

You'll then receive an email with an invite to accept. Once you click the "Let's go!" link, it will take you to the sign-in or account creation page. You need to sign in or enter info to create a new account.

If you need more insights about users in QBO, you can read through this article: Manage users in QuickBooks Online.

Please let me know in the comments below if you have any other questions. Stay safe!

We've already done this, it connects me to a trial that I was using for my wife's company and does not allow me to switch over to the company I work for.

I'm here to help you with this, Adam Forist.

I suggest checking the Manage users page for both companies. Then, check if the user in question and email are listed on both accounts.

If the problem continues, I suggest contacting our QuickBooks Support Team. They have tools to check your account in a secure environment.

Here's how:

1. Sign in to your QuickBooks Online company.
2. Select Help (?) at the top right.
3. Select or type Contact Us.
4. Enter your concern, then select Let's talk.
5. Choose a way to connect with us.  

Also, I've got you this reference helpful in managing a user's roles and limiting their access to specific tasks: User roles and access rights in QuickBooks Online.

I'll be looking forward to hearing back from you. Have a wonderful day!
