Calculated as length × width × height divided by a carrier-specific divisor. DIM weight optimization — through right-sizing packaging — directly reduces shipping costs. [Read full definition](/resources/b2b-technology-glossary/dim-weight-dimensional-weight) ### [FBA Fulfillment by Amazon ](/resources/b2b-technology-glossary/fba-fulfillment-by-amazon) Amazon's fulfillment service where sellers send inventory to Amazon's fulfillment centers, and Amazon handles storage, pick-and-pack, shipping, and customer service for those orders. FBA products are Prime-eligible and benefit from Amazon's logistics network, but FBA fees and inventory placement complexity require careful margin management. [Read full definition](/resources/b2b-technology-glossary/fba-fulfillment-by-amazon) ### [FBM Fulfillment by Merchant ](/resources/b2b-technology-glossary/fbm-fulfillment-by-merchant) An Amazon selling model in which the seller stores, picks, packs, and ships orders independently — rather than using Amazon's FBA network. FBM gives sellers more control over inventory and branding but requires meeting Amazon's shipping speed and reliability standards to remain competitive. [Read full definition](/resources/b2b-technology-glossary/fbm-fulfillment-by-merchant) ### [FTL Full Truckload ](/resources/b2b-technology-glossary/ftl-full-truckload) A freight shipping mode in which a single shipment fills an entire truck trailer.

[Read full definition](/resources/b2b-technology-glossary/ftl-full-truckload) ### [LTL Less Than Truckload ](/resources/b2b-technology-glossary/ltl-less-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. [Read full definition](/resources/b2b-technology-glossary/ltl-less-than-truckload) ### [MCF Multi-Channel Fulfillment ](/resources/b2b-technology-glossary/mcf-multi-channel-fulfillment) Amazon's service that allows sellers to use their FBA inventory to fulfill orders from non-Amazon channels — such as Shopify, BigCommerce, or their own website. MCF enables a single inventory pool to serve multiple sales channels, simplifying operations but adding per-unit fees. [Read full definition](/resources/b2b-technology-glossary/mcf-multi-channel-fulfillment) ### [Pick and Pack ](/resources/b2b-technology-glossary/pick-and-pack) The warehouse process of selecting (picking) specific items from storage locations and packaging (packing) them for shipment to the customer. Pick-and-pack efficiency — measured in units per hour and error rate — is one of the primary cost drivers in fulfillment operations. [Read full definition](/resources/b2b-technology-glossary/pick-and-pack) ### [POD Proof of Delivery ](/resources/b2b-technology-glossary/pod-proof-of-delivery) Documentation or electronic confirmation that a shipment was received by the consignee. POD may include a signature, photo, or carrier scan event. Required for dispute resolution, chargeback defense, and accounts receivable processes. [Read full definition](/resources/b2b-technology-glossary/pod-proof-of-delivery) ### [Putaway ](/resources/b2b-technology-glossary/putaway) The warehouse process of moving received inventory from the receiving dock to designated storage locations.

[Read full definition](/resources/b2b-technology-glossary/putaway) ### [Returns Management Reverse Logistics ](/resources/b2b-technology-glossary/returns-management-reverse-logistics) The set of processes and systems involved in receiving, inspecting, grading, restocking, or disposing of returned merchandise. Effective reverse logistics requires integration between the carrier, WMS, OMS, and ERP to accurately update inventory and trigger refunds or replacements. [Read full definition](/resources/b2b-technology-glossary/returns-management-reverse-logistics) ### [SFP Seller Fulfilled Prime ](/resources/b2b-technology-glossary/sfp-seller-fulfilled-prime) An Amazon program allowing qualified sellers to display the Prime badge on orders they fulfill themselves — without using FBA — by meeting Amazon's strict two-day delivery, cancellation rate, and tracking requirements. SFP gives brands Prime visibility while maintaining control of their own fulfillment operation. [Read full definition](/resources/b2b-technology-glossary/sfp-seller-fulfilled-prime) ### [SLA Service Level Agreement ](/resources/b2b-technology-glossary/sla-service-level-agreement) A formal commitment between a fulfillment provider and a merchant defining performance standards — such as order cut-off times, same-day ship rates, accuracy rates, and damage rates. SLA compliance is measured through WMS and OMS reporting and directly impacts customer satisfaction and marketplace seller metrics. [Read full definition](/resources/b2b-technology-glossary/sla-service-level-agreement) ### [Slotting ](/resources/b2b-technology-glossary/slotting) The strategic placement of products in warehouse storage locations to minimize pick travel time and improve throughput. High-velocity SKUs are slotted near packing stations; slow-movers are placed in less accessible locations. Slotting optimization is managed by WMS algorithms. [Read full definition](/resources/b2b-technology-glossary/slotting) ### [WMS Warehouse Management System ](/resources/b2b-technology-glossary/wms-warehouse-management-system) Software that controls and optimizes warehouse operations including receiving, putaway, picking, packing, and shipping. WMS platforms integrate with ecommerce and ERP systems to maintain accurate inventory visibility and fulfill orders efficiently. Examples include Manhattan Associates, HighJump, and ShipBob's native WMS. [Read full definition](/resources/b2b-technology-glossary/wms-warehouse-management-system) ### [Zone Skipping ](/resources/b2b-technology-glossary/zone-skipping) A carrier cost-reduction strategy in which a seller consolidates parcels and injects them into a carrier's network closer to the delivery destination, bypassing upstream sortation zones. Zone skipping reduces per-parcel shipping cost but requires regional inventory positioning or 3PL network coverage. [Read full definition](/resources/b2b-technology-glossary/zone-skipping) ## Amazon & Marketplace Acronyms The essential vocabulary for brands selling on Amazon and major marketplaces — from performance metrics to program names and seller operations. 21 terms ### [ACOS Advertising Cost of Sale ](/resources/b2b-technology-glossary/acos-advertising-cost-of-sale) The ratio of Amazon ad spend to attributed ad revenue, expressed as a percentage. ACOS = Ad Spend ÷ Ad Revenue × 100. A lower ACOS indicates more efficient advertising.
