Currently I have two vendors that drop ship on our behalf. I have all the products that they ship set up as non-inventory. These products are not low value items. They can range from $100 to $10,000. In searching around the Q&A forums I found an answer that states "Then, you can choose to use non-inventory items only when the value of that stock is not significant, or if you are recording the stock value manually through accounts other than inventory."

The process is typically I receive an order via my ecommerce site. That order sits there until I mark it fulfilled at which point the order pushes over to QBO as an invoice. When I first received the order I created a PO that was then submitted to the vendor. All this seems to be working fine. 

My question is since these products are set up as non-inventory but are still high value am I approaching this correctly or should I be treating them as inventory? One issue I have is it becomes a bit of a pain to calculate my margins as COGS are not recorded. I do realize that the expense floats up but would be nice to see the COGS so as to easily be able to calc my margins. But that isn't a show stopper. 

What is everyone's recommendation? Treat these products as inventory item even though I never take physical possession or leave as non-inventory and just calculate the margins manually?

Thanks in advance.
