Distribution & Logistics Glossary

Key wholesale distribution and logistics terms — 3PL, MOQ, OTIF, ASN, and more.

Distribution & Logistics Glossary

3PL (Third-Party Logistics)

A partner that stores, picks, packs, and ships inventory on your behalf. See our What Is 3PL guide.

ASN (Advanced Shipping Notice)

Electronic notice (often EDI 856) telling the buyer what is shipping, when, and in what packaging — critical for receiving appointments.

Backorder

An order line you accept when stock is unavailable, promising later fulfillment. High backorder rates erode trust unless communication is proactive.

Chargeback

A financial penalty from a retailer or buying group for ASN errors, late deliveries, labeling mistakes, or fill-rate misses.

COGS (Cost of Goods Sold)

Direct product cost recognized when you sell. For distributors, track landed COGS — not only supplier invoice price.

Core / Core Charge

In auto parts, a refundable deposit on rebuildable components returned for remanufacturing.

Cycle Count

Ongoing inventory counting by location or SKU class instead of a single annual physical — improves accuracy without full shutdowns.

Dimensional Weight (DIM)

Carrier billing method using package volume, not only scale weight. Oversized light boxes inflate freight cost.

DSO (Days Sales Outstanding)

Average days to collect payment after a sale. Critical cash-flow metric for distributors extending Net 30 terms.

EDI (Electronic Data Interchange)

Standardized electronic documents between distributors and large retail or institutional buyers (e.g., 850 PO, 810 invoice).

ERP (Enterprise Resource Planning)

Integrated software for finance, inventory, purchasing, and sales. See Best ERP for Distributors.

FEFO (First Expired, First Out)

Pick dated product by earliest expiry first — standard in food, medical, and cosmetics.

Fill Rate

Percentage of ordered lines or units shipped complete on the first attempt. A core service KPI for wholesalers.

FOB (Free on Board)

Shipping term defining when title and freight responsibility transfer from seller to buyer.

Incoterms

ICC rules (e.g., FOB, CIF, DDP) that allocate freight, insurance, and risk between buyer and seller on international shipments.

Landed Cost

Total cost to get a unit into your warehouse: product + freight + duty + insurance + broker fees + other inbound costs.

Line Card

The brands and categories you are authorized or positioned to sell — your commercial identity to buyers.

LTL (Less Than Truckload)

Freight mode for pallet shipments that do not fill a full trailer; watch accessorials and transit variability.

MAP (Minimum Advertised Price)

Supplier policy restricting how low authorized resellers may advertise prices — common in electronics and branded goods.

MOQ (Minimum Order Quantity)

Smallest order a supplier will accept. See Minimum Order Quantity (MOQ) guide.

MRP (Material Requirements Planning)

Production planning focused on materials and BOMs. Compare ERP vs MRP for distributors.

Net 30

Payment due 30 days after invoice. Improves buyer convenience but increases your DSO and working-capital need.

OTIF (On Time In Full)

Orders delivered by the promised date with complete quantities — stricter than fill rate alone.

Putaway

Warehouse process of moving received goods into storage locations; directed putaway improves slotting accuracy.

RMA (Return Merchandise Authorization)

Controlled process for customer returns — essential to limit credit leakage and restocking chaos.

Safety Stock

Buffer inventory held against demand and lead-time variability to protect fill rate.

SKU (Stock Keeping Unit)

Unique identifier for each product variant you stock and sell.

Slotting

Assigning SKUs to warehouse locations by velocity and cube to cut travel time and pick errors.

VMI (Vendor-Managed Inventory)

Supplier monitors your stock and replenishes based on agreed min/max levels.

WMS (Warehouse Management System)

Software for receiving, putaway, picking, and shipping in a warehouse. See Best WMS guide.

Working Capital

Cash tied in inventory and receivables minus payables. Distribution businesses are working-capital machines — model it explicitly.
