We keep significant quantities of customers inventory (they purchased from us but not delivered yet for various reasons) and we charge them rent. What is the best practice for this? Thank you.

This is something very difficult to accomplish in NS. Is the location where you keep this inventory shared with your inventory? If you could create a different sub/location and put it there, you could prob handle it that way, but it would presumably require lots of extra transactions.

Yeah. Using a virtual location is too messy. But thanks!
