A warehouse management system (WMS) is a key part of the supply chain and primarily aims to control the movement and storage of materials within a warehouse and process the associated transactions, including shipping, receiving, putaway and picking. The systems also direct and optimize stock putaway based on real-time information about the status of bin utilization. A WMS monitors the progress of products through the warehouse. It involves the physical warehouse infrastructure, tracking systems, and communication between product stations.[1]

More precisely, warehouse management involves the receipt, storage and movement of goods, (normally finished goods), to intermediate storage locations or to a final customer. In the multi-echelon model for distribution, there may be multiple levels of warehouses. This includes a central warehouse, a regional warehouses (serviced by the central warehouse) and potentially retail warehouses (serviced by the regional warehouses).

Warehouse management systems often utilize automatic identification and data capture technology, such as barcode scanners, mobile computers, wireless LANs and potentially radio-frequency identification (RFID) to efficiently monitor the flow of products. Once data has been collected, there is either a batch synchronization with, or a real-time wireless transmission to a central database. The database can then provide useful reports about the status of goods in the warehouse.

Warehouse design and process design within the warehouse (e.g. wave picking) is also part of warehouse management. Warehouse management is an aspect of logistics and supply chain management.


Warehouse management systems can be standalone systems, or supply chain execution suite, modules of an ERP system such as Odoo or Visual World. Depending on the size and sophistication of the organization, the system can be as simple as a handwritten list that are updated when required, spreadsheets using software such as Microsoft Excel or Access or purpose-built software programs.[2]

In its simplest form, the WMS can track product's data during the production process and act as an interpreter and message buffer between existing ERP and WMS systems.
