The Path to Enhancing Corporate Inventory Turnover Efficiency Through Seamless Integration of ERP and WMS

Targeting the core pain points of slow inventory turnover in the fast-moving consumer goods (FMCG) industry, such as “data fragmentation, process disconnection, and cost-efficiency imbalance” in the integration of ERP and WMS, this paper constructs a three-tier enhancement model of “data integration – process reengineering – intelligent optimization.” It systematically reveals the internal transmission mechanism of “data granularity – process collaboration – inventory turnover rate.” Based on panel data from 15 FMCG companies with annual revenues of ≥5 billion yuan, an empirical comparison is conducted among the control group (traditional batch processing integration), experimental group 1 (only data integration), and experimental group 2 (full three-tier model). The study quantifies the efficiency differences and cost boundaries of different integration modes. The findings indicate that the three-tier model can reduce inventory turnover days from 45 days to 32 days (a relative improvement of 29%), lower the stockout rate to 3.2%, and decrease system maintenance costs by 38% compared to the “real-time synchronization” solution. The transmission coefficient of “data – process – efficiency” reaches 0.63 (p
