Why am I seeing this error message in my Transaction log:
Order item (*your store item*) has no SKU. System will use unknown_do_not_delete as the SKU
This means that our software found an item on the order it was trying to sync, but this item does not exist in QuickBooks. Because your settings indicate that you want our software to create new items in QuickBooks, [Found in your settings under the "Missing Products " Tab] it is attempting to create the item, however, there is nothing in the SKU field in your store. Our software doesn't know what to put in the item name field in QuickBooks, so it enters unknown_do_not_delete, and creates the item.
When you see this error message come through, find the item in your store and add a SKU, then find the item in QuickBooks and change the Item Name to the same as the SKU in your store, so that future syncs will match the items.
Example of item in a store with no SKU:
