In fact, in my opinion, purchasing is not just about buying things, it contains a lot of practical knowledge. For example, the understanding of the overall market situation of purchased products, the distribution of manufacturers, price, quality and so on. Then there is the understanding of the manufacturers, the scale, reputation, after-sales, the subsequent redevelopment ability of the products (this is very important, and good accessories can also enhance the market competitiveness of their products), and the development prospects of the enterprises (you don't want to close down just after implementing a supplier). It is also important to have good communication skills and coordination mechanism with manufacturers and enterprises. There is nothing perfect in the world, especially products. There will definitely be such problems in the future, such as market coordination or money problems. In addition, you must have knowledge and communication skills related to logistics and warehouse management. So there is a lot to learn. If you really learn, there will be a market.
