Establishing a good supplier relationship can meet the changing needs of enterprises and improve the work efficiency of procurement personnel. In the past, many enterprises regarded suppliers as rivals and dealt with them on this basis. In Japan's experience, good supplier relationship brings many benefits, that is, obtaining flexible suppliers who can accept changes in delivery time, quality and quantity. In addition, suppliers can always help find problems and propose solutions. Therefore, it is a short-sighted method to select and replace suppliers solely on the basis of price, which cannot meet the changing needs of enterprises. Many Japanese companies only need a few suppliers to meet the demand. On the contrary, many domestic purchasing enterprises are dealing with countless suppliers. They believe that "the snipe and the clam compete, and the fisherman gains." Actually, it's not, and the supplier is not that stupid. Therefore, the best way is to establish a good partnership with suppliers. In this way, suppliers can supply with high quality, operate strictly according to delivery time, and maintain flexibility related to changes in production specifications and delivery time. Two diametrically opposed supplier views are shown in the following table: In general, suppliers can make suggestions for purchasing enterprises and improve their competitive advantage through the following nine points. (1) Reduce the purchase cost. (2) Improve customer satisfaction. (3) Reduce transportation costs. (4) Improve product quality. (5) Reduce the production cost. (6) Improve product design. (7) Reduce inventory costs. (8) Introducing new products or new processes. (9) Shorten the time for products to reach the market. If purchasing companies have a good relationship with suppliers, they will usually accept their opinions generously. Only when * * * is committed to reducing inventory, planning and stabilizing production can the supplier partnership cooperate happily. Generally speaking, buyers or suppliers should be large.
