Assess multimodal access (road, rail, air, sea), proximity to major highways and ports, last‑mile courier coverage, and available freight lane density. Verify carrier integrations, dock configurations, and whether the 3PL supports cross‑docking, bonded storage, and temperature‑controlled handling to match your product profile.

Compare base storage and handling rates, inbound/outbound freight assumptions, pick‑and‑pack labor models, and value‑added service fees. Request sample rate cards and modeled scenarios for typical SKUs, include transit‑time estimates to major markets, and evaluate SLAs and historical on‑time fulfillment metrics.

Look for real‑time WMS integrations, SKU‑level inventory visibility, scalable pick/pack workcells, returns processing, kitting, and multi‑carrier shipping options. Ensure the 3PL can handle peak volume spikes and offers automated labeling, API connectivity, and clear KPIs for order accuracy and lead times.

Evaluate contingency plans for carrier disruptions, disaster recovery, labor shortages, and capacity constraints. Confirm expansion options, minimums, exit terms, inventory security, and technology portability. Consider running an initial pilot to validate performance before a full contract commitment.
