The planning and management of the movement and storage of goods, services, and related information from origin to the point of consumption, aimed at meeting customer requirements at the lowest total cost.
- Total landed cost
- Related: Cost trade-off, Activity-based costing
The sum of every cost incurred to get a product to the customer, including purchase price, transportation, duties and tariffs, handling, inventory carrying cost, and risk or quality costs.
- Cost trade-off
- Related: Total landed cost, Inventory carrying cost
A situation in which reducing cost in one logistics activity raises cost in another, so alternatives must be judged on their combined effect rather than on a single function's expense.
- Perfect order
- Related: Service level, Key performance indicator (KPI)
A customer service measure counting orders delivered complete, on time, damage-free, and with correct documentation, usually expressed as a percentage of all orders handled.
- Bullwhip effect
- Related: Demand forecasting, Safety stock
The tendency for demand variability to grow as orders move upstream from the end customer toward suppliers, producing excess inventory, distorted forecasts, and poor capacity utilization.
- Reverse logistics
- Related: Perfect order
The processes for moving products backward from the customer, covering returns, repairs, recalls, recycling, and disposal, together with the information flows and value recovery that accompany them.
- Third-party logistics provider (3PL)
- Related: Freight consolidation, Logistics risk management
An external firm that performs logistics activities such as transportation, warehousing, or order fulfillment for a shipper under contract, letting the shipper concentrate on its core business.
- Lead time
- Related: Safety stock, Reorder point
The total elapsed time from when a customer order is placed until the goods are received, covering order processing, sourcing or production, and transportation.
- Service level
- Related: Perfect order, Safety stock
The target or achieved performance of a logistics operation against customer expectations, commonly stated as the share of demand met on time or filled from available stock.
- Demand forecasting
- Related: Bullwhip effect, Sales and operations planning (S&OP)
Estimating future customer demand for products or services from historical data, market intelligence, and statistical methods, as a basis for inventory, capacity, and procurement plans.
- Sales and operations planning (S&OP)
- Related: Demand forecasting, Distribution requirements planning (DRP)
A recurring cross-functional process that balances demand plans against supply capability - production, inventory, and distribution - to produce one agreed operating plan for the business.
- Inventory carrying cost
- Related: Economic order quantity (EOQ), ABC analysis
The cost of holding inventory over time, including capital tied up, storage, insurance, taxes, obsolescence, shrinkage, and handling, usually expressed as a percentage of inventory value per year.
- Economic order quantity (EOQ)
- Related: Inventory carrying cost, Reorder point
A formula-based order size that minimizes the combined ordering cost and inventory carrying cost, balancing the expense of frequent small orders against the expense of holding large ones.
- Safety stock
- Related: Reorder point, Lead time
Extra inventory held to protect against uncertainty in demand or supply during the replenishment lead time, lowering the risk of stockouts that were not planned for.
- Reorder point
- Related: Safety stock, Lead time
The inventory level that triggers a replenishment order, calculated from expected demand during the lead time plus a buffer for variability in that demand or supply.
- ABC analysis
- Related: Cycle counting, Inventory carrying cost
A classification technique that groups inventory items or customers by value or volume - A highest, C lowest - so control effort is concentrated where the financial impact is greatest.
- Distribution network design
- Related: Distribution requirements planning (DRP), Total landed cost
Deciding how many warehouses, plants, and flow points to use, where to locate them, and which customers each serves, so service targets are met at the lowest total cost.
- Distribution requirements planning (DRP)
- Related: Distribution network design, Safety stock
A time-phased method that works backward from customer demand at each distribution point to set inventory levels and schedule replenishment shipments through the distribution network.
- Order cycle
- Related: Lead time, Perfect order
The sequence of activities from order receipt through credit check, picking, packing, shipping, and delivery; its total elapsed time is measured as order cycle time.
- Cross-docking
- Related: Freight consolidation, Warehouse management system (WMS)
A flow-through technique in which inbound goods are unloaded, sorted, and transferred directly to outbound vehicles with little or no storage, cutting handling and inventory.
- Warehouse management system (WMS)
- Related: Slotting, Cycle counting
Software that directs and records warehouse activity - receiving, put-away, picking, packing, and shipping - including task allocation, location control, and real-time inventory visibility.
- Transportation management system (TMS)
- Related: Freight consolidation, Bill of lading
Software used to plan, execute, and settle freight movements, covering mode and carrier selection, load building, routing, rating, tendering, tracking, and freight payment.
- Slotting
- Related: Warehouse management system (WMS), ABC analysis
Assigning stock-keeping units to warehouse storage locations based on pick frequency, cube, weight, and affinity, so that travel time falls and picking productivity rises.
- Freight consolidation
- Related: Milk run, Cross-docking
Combining smaller shipments from multiple orders, suppliers, or customers into one larger load so cost per unit falls and transport equipment is better utilized.
- Milk run
- Related: Freight consolidation, Last-mile delivery
A route in which one vehicle visits several locations on a fixed schedule, collecting or dropping partial loads, to improve vehicle utilization and reduce transport cost.
- Incoterms
- Related: Total landed cost, Bill of lading
Standard international trade terms published by the ICC that state who arranges and pays for transport, insurance, and customs clearance, and where risk and cost pass between buyer and seller.
- Bill of lading
- Related: Incoterms, Transportation management system (TMS)
A transport document issued by the carrier that acts as a receipt for the goods, evidences the contract of carriage, and in negotiable form can transfer title to them.
- Last-mile delivery
- Related: Milk run, Service level
The final leg of a shipment from the last distribution point to the end customer, usually the most expensive and least efficient part because of small drops and urban constraints.
- Key performance indicator (KPI)
- Related: Perfect order, Balanced scorecard
A selected measure tied to a strategic objective that quantifies how well a logistics process performs and is tracked over time against a target to guide decisions.
- Balanced scorecard
- Related: Key performance indicator (KPI), Benchmarking

A costing method that assigns overhead to products or orders according to the activities they consume, giving more accurate cost visibility for logistics services with varied handling needs.
- Cycle counting
- Related: ABC analysis, Warehouse management system (WMS)
A continuous inventory verification method in which a small number of items or locations are counted on a rotating schedule instead of in one annual physical inventory, with errors investigated and corrected.
- SCOR model
- Related: Benchmarking, Key performance indicator (KPI)
