Turnover stock is the term used to describe inventory or goods that are regularly bought and sold by a company as part of their operations. This includes items such as raw materials, products or parts which are converted into finished goods for sale. Companies calculate their turnover stock in order to get an accurate picture of their business performance and to optimize their operations. By tracking turnover stock, companies can ensure that they maintain the right balance between supply and demand, leading to more efficient processes and better profit margins.
