Yes that’s correct!
Hmm, you bring up a good point about the inventory scenario. They are all Qty Bearing. But we only use inventory for efficiency purposes (ordering direct to a sales order). I would have to get input from the users to see which feature is more important.
Very good point! Thank you. Just made this problem a little messier 
we have requested something close to that, basically linking unique pricing from x supplier to z customer, it’s been added to the Idea’s page on Epicor and marked for future consideration

as we have a similar situation, some of our customers get special pricing from some suppliers
