I am experiencing similiar issue with SOF worksheet.  We have an online store with woo commerce and our orders are syncing and pushed thru third part app My Works Sync that pushes order into qbooks.  It works great for all items that are inv parts when order is placed online, it pushes into SOF worksheet.  However, if someone orders 4 items from online store  that are deemed inv parts in qbooks and then 1 item that is a non-inventory part, the order is pushed thru successfully to SOF workshet but it only shows the 4 items, the other item is missing and does show up on pick slip.  We need to manually add.

Now if someone orders 4 items from store that are deemed non-inv part in qbooks, then nothing is pushed into the SOF worksheet.... But instead the sales order will show up under that customer in the customer center and we are not notified of the order in the end..  We live and breathe in the SOF worksheet. So it would be great to have funcitionality work the same for inv part and non-inv part.  Any help or suggestions?
