Allow me to share insight on how to fix the error QBWC1013 error connecting to Quickbooks

This problem is typically caused when QuickBooks Web Connector doesn't have permission to open QuickBooks.  To fix, delete the connection in Web Connector then recreate it.

Note: Make sure QuickBooks is in a Single User Mode. You logged into QuickBooks as an Admin User. The  Admin user has a password since the Web connector will not work properly if the Admin user has no password. 

You can check out this article to learn how to set up QuickBooks Web Connector and to avoid errors after installing: Set up QuickBooks Web Connector.
