This guide is provided by Conductor, the service that powers the QuickBooks Desktop integration for many business tools, including the one that sent you here.
Each QuickBooks Desktop Web Connector connection is associated with a specific QuickBooks Desktop user account. This guide will show you how to change which user account a connection uses.
If the QuickBooks Desktop user ever signs in on another computer, this connection will not work properly. Make sure to select a user who primarily works on the same computer to avoid conflicts.
The QuickBooks Desktop user you select should have “Full Access” permissions to ensure the connection works correctly with all the data it needs to access.
