Direct Ship
Does a direct ship order consume inventory at the buyer's warehouse?
No. The direct ship order is tracked as demand but does not affect the buyer's inventory quantities because the buyer never takes physical possession of the goods.
What system objects are usually created in an ERP for direct ship?
Typically a sales order for the customer and a linked purchase order to the supplier are created. The supplier ships directly to the customer, bypassing the buyer's warehouse.
Why do manufacturers use direct ship instead of warehouse fulfillment?
To reduce handling cost, storage cost, and lead time when the item can be fulfilled more efficiently from supplier stock than from internal inventory.
Direct ship is a fulfillment method where goods are sent directly from the supplier, manufacturer, or origin facility to the customer or receiving location, bypassing the shipper's warehouse and intermediate storage. In ERP, a sales order triggers a linked purchase order, and the supplier ships straight to the customer; the quantity never hits the seller's inventory balance.
On the shop floor, direct ship is used when a plant sells an item fulfilled from supplier stock rather than picked from its own warehouse. A buyer creates a purchase order tied to the customer sales order, and the supplier ships to the customer or designated site while the system tracks demand and supplier commitment. Warehousing gains emerge because receiving, putaway, and internal picking disappear when the item never enters the central warehouse. This suits bulky, slow-moving, or customer-specific items otherwise consuming space and handling capacity. For raw material, vendor-managed or customer-directed replenishment flows allocate stock at source, with ERP tracking shipment status, lot/serial reference, and delivery confirmation without warehouse stock movement at the buyer site. Direct ship shifts execution focus to order orchestration, PO transmission, ASN handling, carrier tracking, and receipt confirmation, trading lower storage and handling costs for greater reliance on supplier execution, transport coordination, and visibility.
Inventory illusion: Planners may assume material is available because the sales order is confirmed, but if the supplier's stock is not actually reserved, the shipment fails late and creates a customer-facing stockout with no internal warehouse buffer to recover.
Receiving and documentation mismatch: An improperly linked sales order, purchase order, shipment confirmation, and ASN leaves an open order with no warehouse receipt event, creating mismatched quantity, lot, or serial traceability and delaying invoice reconciliation.
Transport bottleneck: Because direct ship uses a single leg and no consolidation node, a late carrier pickup, supplier dock delay, or incorrect ship-to address immediately becomes a delivery failure with no distribution center to re-route, re-label, or re-stage the load.
