Metapack, a ShipStation Global® brand and leader in ecommerce delivery management, was today named a strategic partner for delivery management by OneStock, a leading provider of AI-driven Order Management Systems (OMS). The partnership connects OneStock's inventory orchestration with Metapack's global carrier network, giving enterprise retailers a single stack from order placement through to carrier selection, label generation, and branded returns.
Metapack named OneStock's strategic delivery management partner.
Partnership covers checkout, orchestration, execution, and returns.
Metapack processes 1B+ shipments annually across 350+ carriers and 4,000+ services.
Retailers can expect 10%+ conversion increase and 20-52% of orders via store networks.
Combined stack reduces shipping costs by up to 40%.
ShipStation Global serves 3M+ customers and moves 3B+ shipments per year.
The combined stack covers checkout with real-time, location-aware delivery options backed by live inventory data; orchestration where OneStock routes each order to the optimal fulfillment source; execution where Metapack automates carrier selection from its network of 350+ carriers and handles label generation; and returns with a branded returns journey that integrates Metapack's returns portal with OneStock's restocking logic.
Retailers using the joint stack can expect 10%+ increase in conversion rates driven by transparent, reliable delivery choices at checkout; 20-52% of online orders fulfilled via existing store networks, reducing shipping costs by up to 40%; up to 20-30% increase in turnover driven by unified stock and surfacing store-level inventory to online customers; and 40-77% fewer WISMO calls related to stock availability queries, delivery uncertainty, or order cancellations.
