Stock Transfer Order
A Stock Transfer Order (STO) is an internal order to move inventory between facilities owned by the same company (DC to DC, plant to warehouse, warehouse to store), managed through the ERP as a logistics transaction that changes inventory location without changing ownership.
Why It Matters
STOs are the invisible shipments of the supply chain. In SAP, inventory shows as 'in transit' but nobody knows when it will actually arrive, whether the truck is delayed, or whether the receiving DC should adjust its labor plan. When STOs represent internal rebalancing to prevent stockouts, this invisibility is costly.
The FourKites Perspective
The FourKites Order Twin models STOs with the same visibility and intelligence as customer-facing orders. The Shipment Twin tracks the physical movement. The Inventory Twin updates both the sending and receiving facility positions in real time. When an STO shipment is delayed, the system recalculates the receiving facility's inventory projection automatically.
