What’s the difference between a Warehouse Management System (WMS) and a Warehouse Execution System (WES)?

Warehouse Management Systems manage common operations such as inventory control, customer orders, and auditing whereas Warehouse Execution Systems are typical in facilities with moderate-to-heavy levels of automation. The WES generally interfaces with the WMS to organise and optimise the flow of work required to assemble and ship orders. In addition, the WES interfaces with the automation controls to execute the work – it’s the WES that controls the robots!
