Shipping & Fulfillment Glossary

Backorder

A backorder happens when a product is temporarily out of stock after a customer places an order. Instead of canceling the purchase, the business keeps the order active and ships the item once inventory arrives. Backorders are common in e-commerce fulfillment, retail distribution, and manufacturing operations during periods of high demand or supplier delays.

Frequent backorders can increase lead times and create customer frustration if communication is delayed. Accurate inventory management and forecasting help reduce stock shortages and keep fulfillment operations moving efficiently.

Bill of Lading (BOL)

A Bill of Lading, often called a BOL, is a shipping document used during freight transportation. It acts as a receipt for goods and records important shipment details such as product type, quantity, destination, and carrier information.

Warehouses, carriers, and fulfillment providers use BOLs to track freight movement and confirm cargo transfers throughout the shipping process. Accurate documentation helps reduce delivery disputes, delays, and billing errors. In logistics operations, a Bill of Lading supports organized freight shipping and clear communication between all parties involved.

B2B Fulfillment

B2B fulfillment refers to the storage, processing, and shipping of products from one business to another. Common examples include manufacturers shipping inventory to retailers, distributors, or wholesale buyers. These orders usually involve larger shipment volumes, palletized freight, and scheduled delivery requirements. Accurate inventory tracking and organized freight coordination help businesses maintain steady product flow throughout the supply chain.

B2C Fulfillment

B2C fulfillment refers to the process of storing, packing, and shipping products directly to consumers. This fulfillment model is common in e-commerce and retail operations where customers place individual online orders for home delivery. Fast order processing, accurate picking and packing, and reliable shipping timelines all play a major role in customer satisfaction. Many businesses work with 3PL providers to manage inventory storage and daily order fulfillment operations.

C

Cross-Docking

Cross-docking is a logistics process where incoming products move directly from receiving to outbound shipping with little or no storage time in between. Businesses use cross-docking to reduce warehouse handling, lower storage costs, and speed up delivery timelines. This process is common in retail distribution, grocery operations, and high-volume freight shipping. Accurate scheduling and coordination between warehouses and carriers help products move quickly through the supply chain.

Cycle Count

A cycle count is an inventory auditing method where small sections of warehouse inventory are counted on a scheduled basis instead of completing a full physical inventory all at once. Regular cycle counts help businesses improve inventory accuracy and identify stock discrepancies earlier. Warehouses and fulfillment centers use cycle counting to reduce operational disruptions and maintain more reliable inventory records. Accurate counts also help improve order fulfillment and shipping performance.

D

Dimensional Weight (DIM Weight)

Dimensional weight, also called DIM weight, is a pricing method shipping carriers use to calculate shipping costs based on package size instead of actual weight alone. Large but lightweight packages may cost more to ship because they take up additional space during transportation.

Carriers calculate DIM weight using package length, width, and height measurements. Businesses that use oversized packaging can face higher freight costs, making efficient carton selection and packaging an important part of shipping cost management.

Distribution

Distribution refers to the movement of products from manufacturers or suppliers to warehouses, retailers, businesses, or consumers. The process includes inventory storage, transportation, order processing, and final delivery throughout the supply chain. Efficient distribution helps businesses maintain product availability and reduce shipping delays. Many companies use warehouses, fulfillment centers, and freight carriers together to keep inventory moving efficiently between locations.

Dock-to-Stock

Dock-to-stock refers to the time it takes for incoming inventory to move from the receiving dock into available warehouse storage. The process includes unloading shipments, inspecting products, updating inventory records, and placing goods into storage locations.

Faster dock-to-stock times help warehouses improve inventory availability and reduce fulfillment delays. Efficient receiving procedures, organized warehouse layouts, and accurate inventory systems all help products move quickly from arrival to storage.

E

EDI (Electronic Data Interchange)

EDI, or Electronic Data Interchange, is the electronic exchange of business documents between companies using standardized formats. Common EDI documents include purchase orders, invoices, shipment notices, and inventory updates.

Businesses use EDI to reduce manual data entry, improve communication accuracy, and speed up supply chain operations. Retailers, manufacturers, warehouses, and 3PL providers frequently rely on EDI systems to share order and shipment information quickly between partners.

F

Freight Shipping

Freight shipping refers to the transportation of large quantities of goods using trucks, rail, air, or ocean carriers. Businesses use freight shipping to move inventory between manufacturers, warehouses, distribution centers, and retail locations.

Freight shipments are typically larger than standard parcel deliveries and may involve pallets, containers, or full truckloads. Shipping costs are influenced by factors such as weight, dimensions, distance, and freight class. Organized freight coordination helps businesses maintain steady inventory movement throughout the supply chain.

FTL (Full Truckload)

FTL, or Full Truckload, refers to a freight shipment that uses an entire truck for one shipment. Businesses typically use FTL shipping for large orders that fill most or all trailer space.

FTL shipments usually move directly from pickup to delivery without multiple stops or transfers. This can reduce transit times and lower the risk of freight damage during handling. Manufacturers, distributors, and retailers often choose FTL shipping for high-volume freight movement and time-sensitive deliveries.

Fulfillment

Fulfillment refers to the process of receiving, storing, packing, and shipping customer orders. The process begins when an order is placed and ends when the shipment reaches the customer.

Fulfillment operations may include inventory management, order processing, picking and packing, shipping coordination, and returns handling. Fast and accurate fulfillment helps businesses improve delivery timelines and customer satisfaction. Many companies work with 3PL providers to manage fulfillment operations more efficiently across multiple sales channels.

Fulfillment Center

A fulfillment center is a warehouse facility used to store inventory, process orders, and ship products to customers. Fulfillment centers play a major role in e-commerce, retail distribution, and B2B shipping operations.

Daily activities inside a fulfillment center may include receiving inventory, picking and packing orders, shipping coordination, and returns processing. Organized warehouse systems and accurate inventory tracking help businesses maintain faster order turnaround times and more reliable shipping performance.

I

Inventory Management

Inventory management refers to the process of tracking, storing, and controlling inventory throughout the supply chain. Businesses use inventory management systems to monitor stock levels, product movement, and warehouse inventory in real time.

Accurate inventory management helps reduce stock shortages, overstocking, and order delays. Warehouses, retailers, manufacturers, and fulfillment providers rely on organized inventory tracking to improve order accuracy and maintain steady product availability.

L

Last-Mile Delivery

Last-mile delivery refers to the final stage of the shipping process when a package moves from a distribution center or transportation hub to the customer’s location. This step directly affects delivery speed and customer experience.

Businesses focus on last-mile delivery to improve shipping timelines, tracking visibility, and delivery accuracy. Traffic, route planning, and delivery volume can all impact last-mile performance. E-commerce companies and fulfillment providers frequently invest in faster delivery solutions to meet customer expectations.

Lead Time

Lead time refers to the amount of time between the start and completion of a process within the supply chain. In logistics and fulfillment, lead time can include inventory ordering, production, processing, and shipping timelines.

Businesses track lead times to improve planning, inventory control, and delivery performance. Long or inconsistent lead times can create shipping delays, stock shortages, and fulfillment disruptions. Accurate forecasting and organized logistics operations help reduce delays and improve product flow.

LTL (Less Than Truckload)

LTL, or Less Than Truckload, refers to freight shipping that combines shipments from multiple businesses into one truck. Companies use LTL shipping for freight that does not require a full trailer.

LTL shipping helps reduce transportation costs since businesses only pay for the trailer space their shipment uses. Carriers typically make multiple stops during transit to pick up and deliver freight. This shipping method is common for small to mid-sized freight shipments moving between warehouses, retailers, and distribution centers.

O

Order Accuracy Rate

Order accuracy rate measures how often customer orders are fulfilled correctly without mistakes in products, quantities, packaging, or shipping information. Businesses use this metric to track fulfillment performance and customer satisfaction.

A high order accuracy rate helps reduce returns, shipping errors, and customer complaints. Warehouses and fulfillment providers improve accuracy through inventory tracking systems, barcode scanning, organized picking processes, and quality control checks during packing and shipping.

Order Processing

Order processing includes the steps required to prepare a customer order for shipment after the order is placed. Tasks may include order verification, inventory updates, picking, packing, labeling, and shipping coordination.

Fast and accurate order processing helps reduce shipping delays and fulfillment errors. Warehouses and fulfillment providers use organized workflows and inventory systems to improve processing speed and order accuracy.

P

Pick and Pack

Pick and pack is a fulfillment process where warehouse staff pick products from inventory and pack them for shipment after a customer order is placed. The process is common in e-commerce, retail distribution, and direct-to-consumer fulfillment operations.

Accurate pick and pack procedures help reduce shipping errors, improve order accuracy, and speed up fulfillment timelines. Warehouses often use barcode scanning, organized inventory systems, and packing stations to improve efficiency throughout the shipping process.

Proof of Delivery (POD)

Proof of Delivery, commonly called POD, is documentation that confirms a shipment reached its destination successfully. POD records may include signatures, delivery timestamps, photos, or electronic confirmation from the recipient.

Businesses use proof of delivery to track shipments, resolve delivery disputes, and confirm completed orders. Carriers, warehouses, and fulfillment providers rely on POD records to improve shipment visibility and provide accurate delivery documentation throughout the shipping process.

R

Returns Management (Reverse Logistics)

Returns management, also called reverse logistics, involves the process of handling products that customers return after purchase. The process may include inspecting returned items, restocking inventory, processing refunds, or disposing of damaged products.

Efficient returns management helps businesses reduce product loss, improve customer satisfaction, and keep inventory records accurate. E-commerce companies, retailers, and fulfillment providers use organized return procedures to process returned products quickly and reduce operational delays.

S

Safety Stock

Safety stock is extra inventory kept on hand to help prevent stock shortages caused by supplier delays, unexpected demand increases, or shipping disruptions. Businesses use safety stock to reduce the risk of backorders and fulfillment delays.

Accurate forecasting and inventory tracking help companies determine appropriate safety stock levels. Too little inventory can create shipping interruptions, while excessive inventory may increase storage costs and reduce warehouse space efficiency.

Shipping Carrier

A shipping carrier is a company responsible for transporting packages, freight, or inventory from one location to another. Carriers may handle parcel deliveries, LTL shipments, FTL freight, air cargo, or ocean transportation.

Businesses work with shipping carriers to move products between warehouses, distribution centers, retailers, and customers. Delivery speed, shipping costs, tracking capabilities, and service coverage all play a role when selecting a carrier for fulfillment and freight operations.

Shipping Zones

Shipping zones are geographic regions carriers use to calculate shipping rates and delivery times. Zones are typically based on the distance between the shipment origin and destination.

Lower shipping zones usually mean shorter delivery distances and lower transportation costs, while higher zones involve longer transit routes and increased shipping expenses. Businesses use shipping zones to estimate delivery timelines, manage shipping rates, and plan fulfillment operations more efficiently.

SKU (Stock Keeping Unit)

A SKU, or Stock Keeping Unit, is a unique code businesses use to identify and track individual products in inventory. SKUs are commonly assigned based on details such as product type, size, color, or variation.

Warehouses, retailers, and fulfillment providers use SKUs to organize inventory, track stock movement, and improve order accuracy. Clear SKU systems help reduce picking errors, simplify inventory management, and improve visibility across fulfillment operations.

T

Turnaround Time

Turnaround time measures the amount of time required to complete a process from start to finish. In logistics and fulfillment, turnaround time may apply to order processing, shipping, inventory receiving, or returns handling.

Faster turnaround times help businesses improve delivery performance and customer satisfaction. Warehouses and fulfillment providers track turnaround times to identify delays, improve workflow efficiency, and keep products moving through the supply chain more efficiently.

W

Warehousing

Warehousing involves storing inventory and products inside a facility before distribution or shipment. Warehouses are used to hold raw materials, finished goods, and retail inventory at different stages of the supply chain.

Warehouse operations may include inventory storage, order picking, packing, shipping, and stock tracking. Organized warehousing helps businesses improve inventory visibility, reduce shipping delays, and manage product flow more efficiently across fulfillment and distribution operations.
