DESK53 Sync Error in QuickBooks Desktop Integration

If you see the error:

DESK53 Sync Error: Error while attempting to provision company.

This means there is a connection or permissions issue between the Workspace and QuickBooks Desktop.

QuickBooks Web Connector does not have the required permission to automatically log in and sync.

The DESK53 error typically occurs when:

• QuickBooks Web Connector is not authorized to log in automatically.
• The integration permissions were changed or removed.
