Fulfillment & Logistics

LTLLess Than Truckload

A freight mode where multiple shippers share space on a single truck. LTL is used when a shipment is too large for parcel but too small to fill a full trailer. LTL pricing is based on freight class, weight, and distance. Transit times are longer than FTL due to multiple stops and terminal handling.

3PLThird-Party Logistics

An external provider that manages warehousing, pick-and-pack, and shipping on behalf of a brand. 3PLs require real-time inventory and order data from the merchant's ecommerce and OMS systems to operate accurately. Choosing the right 3PL and ensuring clean data integration is one of the highest-leverage operational decisions a growing brand makes.

4PLFourth-Party Logistics

An orchestration layer above 3PLs — a provider that manages multiple logistics partners, carriers, and 3PLs on behalf of a brand. 4PLs take ownership of the entire supply chain rather than individual warehousing or shipping operations.

ASNAdvance Ship Notice

An electronic notification (EDI 856) sent by a supplier to a buyer before or at the time of shipment, detailing contents, packaging, and carrier information. ASN accuracy is a critical compliance requirement for most major retail partners and a common source of chargebacks when errors occur.

Carrier

A transportation company that physically moves shipments from origin to destination. Common parcel carriers include UPS, FedEx, USPS, and DHL. LTL and FTL freight carriers handle larger commercial shipments. Carrier selection, rate negotiation, and performance monitoring directly impact fulfillment cost and customer satisfaction.

Cross-Docking

A fulfillment technique where inbound shipments from suppliers are unloaded and immediately transferred to outbound vehicles with minimal or no storage time in between. Cross-docking reduces handling costs and speeds delivery but requires precise scheduling and real-time data synchronization.

DIM WeightDimensional Weight

A pricing method used by carriers to charge based on a package's size (volume) rather than its actual weight, when the dimensional weight exceeds the actual weight. Calculated as length × width × height divided by a carrier-specific divisor. DIM weight optimization — through right-sizing packaging — directly reduces shipping costs.
