Industry Standard Definition
View Official Definition
Wholesale / B2B Fulfillment refers to the process of preparing and shipping case- or pallet-level orders to retailers, distributors, or enterprise clients. Unlike DTC fulfillment, it emphasizes routing guide compliance, GS1-128 (UCC-128) labeling, ASN/EDI documentation, and On-Time In-Full (OTIF) delivery metrics. Accuracy and compliance are critical—errors often result in costly chargebacks.

Michael, Senior Supply Chain Analyst at WinsBS Research:
“B2B fulfillment is driven by compliance rather than speed. Every carton, label, and ASN field must align with the buyer’s routing guide. In 2025, leading retailers began measuring OTIF on a shipment-level basis, pushing 3PLs and brands to automate GS1-128 generation and ASN validation directly within their WMS.”
