Making a scientific purchasing plan is a weak link in inventory management of many small and medium-sized enterprises. Many small and medium-sized enterprises often only pay attention to the sales volume of enterprises, but do not pay attention to making inventory purchase plans or paying attention to inventory limit responsibility management, resulting in inventory shortage or inventory backlog. Inventory shortage and inventory backlog usually come from the uncertainty of enterprises' future market forecast, but small and medium-sized enterprises have not made scientific inventory purchase plans because of the uncertainty of the market.
According to the survey, the purchasing staff of small and medium-sized enterprises do not determine the purchasing plan according to the actual needs, but only purchase the inventory according to their own feelings and experiences, which may lead to frequent, blind and random purchases and unreasonable inventory reserves.
Inventory sometimes takes up a lot of working capital, which leads to a significant slowdown in the capital turnover of enterprises. However, some people in charge of purchasing lack professional quality, collude with others to do human business, buy inferior products, sign contracts that are detrimental to the interests of enterprises, and seek some personal gain from them.
