Vendor-managed Inventory
In a 3PL, this describes the instance of a client (vendor) controlling the inventory at the 3PL warehouse. This type of inventory control can be managed in multiple ways including a periodic physical check of inventory by the vendor in order to determine what needs to be supplied to the warehouse. The vendor can also have remote access to the warehouse’s inventory control system (MRP) and order based on the levels of supply and demand visible electronically.
Warehouse Receipt
Receipt for product received into the warehouse.

WMS is software designed to function around three main components: putaway, replenishment, and picking. By directing these three components, the system can logically manage the movement and storage of product in the warehouse.

Zone Picking
Method of order picking where the warehouse is divided into pick zones. Items are picked from each zone and then transferred on a conveyer system from one zone to the next.
