Evaluate drive-time maps to customer clusters, proximity to federal highways and regional ports, carrier lane frequency, and transit-time SLAs. Compare zone-based shipping costs, average lead times to key zip codes, and the 3PL's local consolidation options to assess total landed cost and service trade-offs.

Require a modern WMS with API/EDI connectivity, real-time inventory visibility, order orchestration for multi-channel flows, returns and reverse-logistics processing, SKU-level reporting, and support for value-added services such as kitting, serialization, and temperature control.

Negotiate transparent storage and per-pick rates, receiving and throughput fees, minimums and seasonality clauses, accessorials, SLA penalties, inventory accuracy guarantees, audit rights, and clear definitions for chargebacks and rate escalations to avoid hidden costs.

Request carrier lane matrices, LTL and TL carrier contracts, consolidation and cross-dock options, proof of intermodal access, typical transit times by region, and historical freight spend analyses to evaluate opportunities for zone skipping, consolidation and route optimization.

Perform site visits, review safety and insurance certificates, validate WMS and EDI integration in a pilot, check inventory and cycle-count procedures, obtain customer references, confirm SLA reporting cadence, and document contingency plans for labor or transport disruptions.
