FIN 419 Week 3 Discussion question 1

At one time I heard that Dell was operating with zero net working capital (NWC). ; They would make computers once the order was placed and the payment had been made. ; The cash came in as an asset (cash), which was offset by the liability of unearned revenue. ; It must have taken them a while to get everything in place, so they did not start with zero NWC. ; It sounds great for a business model and I believe it worked well for Dell. ; Has anyone else heard of a company that has done this?
