Normally, it's most common that when syncing with MyWorks Sync, the QuickBooks company you're syncing with be open, and the QuickBooks Web Connector be open as well.

There are a few advanced scenarios where you can sync with multiple QuickBooks companies, or sync with your QuickBooks company even if it's closed.

There are a few requirements QuickBooks has for the Web Connector:

• You cannot run the Web Connector while more than one QuickBooks company is open. (QuickBooks Enterprise)
• If a QuickBooks company is open, and you're running the Web Connector, the company that is open must be the one that was originally connected to when setting up our sync. A different QuickBooks company cannot be open.

If the above requirements are not followed, running the web connector will result in an error.

Syncing with QuickBooks while closed

It is possible to sync with QuickBooks while the entire QuickBooks application (and company) is closed - keeping only the Web Connector application open.

1. In your QuickBooks company, press control + 1 to open a diagnostic window. This will show the full QuickBooks company file path.
    
2. In MyWorks Sync > Connection in your WooCommerce or Shopify admin, area enter this full company file path in the field on this page. 

Once this is entered, the web connector will be able to run the sync even while the QuickBooks company is closed. 

Common issues:

• If the web connector fails to connect once the above is in place, ensure that the ".qbw" extension of your company file is present in the full file path entered above. It should also be lowercase, not uppercase.
• If the web connector still fails to connect, QuickBooks may not be running as a service on your computer. Try opening the QuickBooks application, but not opening any company. If the web connector then runs, this confirms that QuickBooks is not set up to run as a background service on your computer.
