Buyers' problems, seeking solutions.

Based on the products exclusively produced by suppliers (it would be best if a second one can be found), there is no substitute. But also need to continue to buy this product in the future. The other party also admits the mistake and apologizes, which can be done as follows: 1. Replace unqualified parts (rework as much as possible)-the purpose is not to delay production. 2. Seek the reasons and difficulties of the other person's bad (whether it happens occasionally or often)-from the perspective of concern. If it happens occasionally, consider continuing to cooperate and let the other party strengthen management (if it is best to have words, it is ok not to have them-leave evidence for extraordinary use, but leave your own inspection evidence); If it happens frequently, it is difficult for the other party to solve it. It is suggested to reconsider our procurement documents. If the negative inspection standard is too strict, can the inspection standard be lowered (as a last resort, the final quality of the product must be guaranteed)? 3. When appropriate, add relevant quality assurance agreements to the purchase contract, including default deduction. 4. On the premise of active communication, problems can be solved in time. It is better to change someone else. Manufacturers are actively looking for substitutes-upstairs is right, monopoly is rare now.
