Do everything you can to drive down the WCR of your business!
Lot of business investment goes into inventory prediction and control.
Things we have done: get money upfront, use prediction models and calendar to control inventory buying, use drop shipping and vendor credit where able, push collections efforts, split invoicing.....
This.
You also can't get into a lot of industries without holding inventory. Take your examples. Apple is in the manufacturing and distribution space. Macy's is in retail. For Macy's to be successful, they can't have customers come in and buy clothes 50+ days ahead of time. They have to hold inventory, and accurately predict the returns on inventory in order to get a return.
Same with a lot of other industries.
Inventory is only evil if you cannot accurately predict your risk on investing in that inventory.
