Just to make sure I understand correctly, I should set up a sub COGS account for the product and then link the product to that particular COGS account and that would allow me to track that product outside of just the general COGS. I must be missing something as even after I have isolated a non-inventory item to its own sub COGS expense account I still am not able to view a margin for it when I run a report for sales by product/service summary.
