Forgive me if this has been answered. I've searched and found nothing.

My company has historically operated with zero inventory. We simply place POs with vendors when we receive a PO from a customer and either drop ship or bill stored so it never hits inventory. We're working to change that model and use inventory to balance and make our order patterns more regular with vendors. As we work to implement this change, we're finding that our business model doesn't appear to fit with Netsuite's approach to inventory and backorders so I'm trying to figure out if I'm simply missing something or if there are changes we can make
