Evaluate direct highway links, proximity to supplier clusters and ports, on-site handling equipment, availability of temperature-controlled space, and uptime for inbound/outbound loading. Also review the 3PL's access to local carrier networks and customs clearance experience to minimize lead-time variability.

Confirm real-time inventory visibility, API integrations for order and shipping management, support for batch and SKU-level reporting, and ease of EDI or marketplace connectors. Pilot integrations and SLA definitions for latency, inventory accuracy, and exception handling are key evaluation steps.

Compare per-pallet and per-SKU storage rates, slotting efficiency, labor productivity benchmarks, outbound pick-and-pack fees, and carrier contract pass-throughs. Factor in inbound handling, seasonal surcharges, and detention or demurrage exposure to calculate true landed fulfillment cost.

Assess average road transit times to primary customer clusters, availability of same-day or next-day LTL and parcel services, frequency of scheduled routes, and consolidation options. Verify carrier performance metrics, redundancy for peak periods, and real-time tracking capabilities to maintain SLA compliance.
