What does inventory affect in a store?

In accounting, inventory is recorded as current asset but it does not generate any profit. In fact, store is place of wastage and inefficiency but a necessary evil to run a business. So, we need to keep the inventory to a minimum level in order to support business as well as to minimize wastage

Thanks

Fully agree with Mr. Fazlur's answer

Inventory is one of the factors that you can control to improve your   profitability. The way you source and manage inventory can impact the different profit levels of your income statement. Ignorance of how to use inventory to your advantage prevents you from maximizing operational efficiency.
