What is a Warehouse Management System (WMS)?

A Warehouse Management System is a software solution that provides visibility into a company’s inventory and manages supply chain fulfillment operations from the distribution center to the store shelf. A WMS helps control and optimize warehouse operations such as receiving, putaway, picking, packing, inventory tracking, and shipping.

It integrates seamlessly with other systems like ERP (Enterprise Resource Planning), TMS (Transportation Management System), and order management platforms to provide a unified logistics infrastructure.
