Hi there, CM99.

QuickBooks Web Connector doesn't require a user license. A user in QuickBooks Desktop can also access the app.

However, this application should be set up on one computer. When a user needs to run the Web Connector, it must be performed on the same computer (where it was set up) and the same QuickBooks Login. 

If two people run it at the same time, you may end up with duplicate data. And it can make the development of the integrated app significantly more complex.

If you need more help with the QuickBooks Web connector, I recommend posting a question to our Intuit Developer Team forum. They manage applications and can provide additional information about this. 

Here's how to contact them.

1. Go to this link: https://help.developer.intuit.com/s/
2. Choose QuickBooks Desktop.
   
3. Click Ask Question.
   
4. If you're asked to sign in to your account, enter your Intuit account credentials.
5. If you don't have an Intuit account, you need to create one.
6. Click again the Ask a Question button, then enter a brief discussion of your concern.
   
7. Click Ask.

I'm adding these links to keep you updated and what version to use.
