客户换掉供应商不外乎服务差、价格高、质量低、交货速度慢、品种少、诚信问题六方面因素，只要解决这六点，加之适时改造生产线、拓展产品门类，企业自会成为客户不可替换的供应商。
The reasons why the customers replaced their suppliers are simply poor service, high price, low quality, slow delivery, low variety, and integrity problems, and as suppliers, we should solve these problems while rebuilding our production lines and diversifying our products to become irreplaceable suppliers.
