During long-term operations, the original supplier system was fragmented, lacking systematic entry and assessment standards. Processes such as procurement price comparison, arrival inspection, and reconciliation and settlement were rough, lacking effective delivery tracking and quality control methods, which easily led to issues such as supply quality fluctuations, delivery delays, and reconciliation disputes. Supply chain stability was insufficient, indirectly squeezing project profit margins. To improve the current situation, the company has restructured its supplier management system, established a closed-loop mechanism for supplier entry, grading, evaluation, and elimination, standardized the entire process of demand reporting, multi-party price comparison, sampling upon arrival, and reconciliation and archiving. It optimized centralized procurement plans based on business needs, established delivery schedule warning and quality review mechanisms, and simultaneously stockpiled backup supplier resources to hedge against supply interruption risks. After the system was implemented, the procurement structure for core categories was continuously optimized, supply stability and product consistency greatly improved, the entire procurement process traceable and traceable, effectively reducing reconciliation conflicts between supply and demand, lowering supply chain risks, and ensuring efficient and orderly delivery of various projects.
