ERP-WMS Integration: When Master Data Falls Out of Sync, Inventory Accuracy Dies

When ERP and WMS inventory numbers never reconcile, the root cause is rarely the interface — it's unsynchronized item master data: mismatched units, missing barcodes, and conversion factors that drift.

Supply Chain Orchestration Is Becoming the Control Layer Between Decisions and Execution

A growing share of supply-chain value is lost in the gap between deciding and doing, argues Logistics Viewpoints. Orchestration is emerging as the control layer that coordinates state, workflow, approvals, actions, retries, and recovery across ERP, TMS, WMS, and partner systems. Governance — which decisions can be automated and which need human approval — determines how far automation can go; buyers should test failure and exception scenarios, not just the happy path.
