Warehouse Execution Software is the application used in warehouse or distribution centers to orchestrate the flow of products from inbound to outbound process.

It organizes a sequence of workflows or operations for man, machines and inventories inside the four walls, including receiving of incoming goods, quality checking, putaway of checked goods in shelves/racks, replenishment of picking locations from the rack, picking the orders, assembling in groups, packing and labelling, loading them into container and shipping.

WES works as a connecting bridge between the ERP and WMS applications. It works in harmony with automated systems like sorters, conveyors, order processing systems like WMS and ERP, and with the inventory on real time basis.
