According to the U.S. Small Business Administration, “Inventory refers to stocks of anything necessary to do business” (U.S. Small Business Administration, 2010, pp 1-2).

When the items are purchased by the consumer, the point-of-sale system reduces the inventory from that purchase. According to Wal-Mart’s Gail Lavielle, a leaner inventory will help clear out store clutter and help Wal-Mart focus on specific brands and products that consumers want (The Associated Press, 2006).
