Quick Reference

Warehouse Management System (WMS)

Software that controls and optimizes day-to-day warehouse operations, including receiving, put-away, inventory tracking, order picking, packing, and shipping, providing real-time visibility into inventory and labor performance.

Order Picking

The process of retrieving items from their storage locations to fulfill customer orders. It is typically the most labor-intensive and costly warehouse activity, representing up to 55% of total operating costs.

Slotting Optimization

The strategic placement of products within a warehouse to minimize travel time, improve picking efficiency, and maximize space utilization, based on factors like velocity, size, weight, and product affinity.

Cross-Docking

A logistics strategy where incoming goods are unloaded from inbound vehicles and loaded directly onto outbound vehicles with minimal or no storage time, reducing handling costs and inventory holding time.

Inventory Accuracy

The degree to which recorded inventory quantities match physical inventory on hand. High accuracy is essential for reliable order fulfillment, financial reporting, and supply chain planning.

Put-Away

The process of moving received goods from the receiving dock to their designated storage locations within the warehouse, guided by put-away rules in the WMS based on product attributes and storage requirements.

Safety Stock

Extra inventory held as a buffer against uncertainty in demand or supply lead times to prevent stockouts and ensure continuous order fulfillment capability.

Material Handling Equipment (MHE)

The machinery and tools used to move, store, control, and protect materials within a warehouse, including forklifts, pallet jacks, conveyors, sortation systems, and automated guided vehicles.

Key Performance Indicators (KPIs)

Quantifiable metrics used to evaluate warehouse performance, including order accuracy, on-time shipping rate, pick rate per hour, inventory turns, and cost per order shipped.

Third-Party Logistics (3PL)

Outsourced logistics services where an external provider manages warehousing, transportation, and distribution functions on behalf of a shipper, offering scalability and expertise without capital investment.
