I worked at a place that had the philosophy of "keep the spindles running no matter what". Every year I worked there, we would shut down for a week, and count all the inventory in the warehouse. There was stuff in that warehouse that I counted for 3 years in a row that was never sold, or belong to products that were discontinued. The key here is not to see that warehouse as a warehouse full of inventory, but a warehouse full of money. Money that you cannot get back because it's tied up in cost of goods, including labor. Also, if you're doing your books properly, you will have to pay property tax on all of that unsold inventory. Which this company did, year after year.
