HI Jane, my inclination would be to post these items directly to COGs, using a non inventory part, as this is a lot of extra work, for what purpose? 

Can you give me a really good reason why it's necessary to break these costs down in a FIFO tracking system?

You could at year end, estimate an approximate cost of shipping and duty to be added to inventory for year end purposes and reversed out the next day if someone needed to be that specific about the cost of inventory held vs COGs during the year.

I'm not sure I would have an easier way to handle this. If it was Desktop, there might be a way to automate, but with QBO, I doubt it. Anyone else care to comment?
