Inventory control was vital to not wasting money in my business. The over stocking of items lead to lots of my inventory wasted due to it being perishable. This made me have to check how long items lasted and how often they were bought. This lead me to have mass stocks of things that lasted a long time and small stocks of things that did not last long. This helped m profit a lot raising by a few thousand within 2 weeks showing it was very important.
