Look for reduced transit times to core markets, carrier aggregation that lowers outbound shipping rates, and 3PLs that provide WMS-driven inventory visibility. Evaluate cross‑dock capability, pick-and-pack speed, returns processing, and SLA commitments to ensure consistent order-to-delivery cycles.

Lower land and labor costs can reduce warehouse rent and handling expenses, improving per‑unit economics. Also consider labor skill for value‑add services, access to transport links for timely shipments, and the presence of automation or technology that increases throughput and reduces error rates.

Negotiate clear SLAs for pick accuracy, order cycle time, and carrier handoff windows; include volume-based rate tiers, minimum notice for capacity changes, liability and insurance clauses, and KPIs with financial remedies for SLA breaches to align incentives.
