Prioritize WMS integration, real‑time inventory visibility, reliable pick‑and‑pack throughput, scalable labor plans, and returns handling. Also assess cross‑dock options, temperature control (if needed), SLA reporting, and carrier integrations to ensure consistent omnichannel performance.

Location drives access to main roads and regional hubs; warehouses closer to primary routes reduce linehaul distance, lower fuel and driver time, and improve delivery windows. Faster transit reduces inventory buffer needs and can materially lower landed cost for both B2B and eCommerce channels.

Compare WMS features, EDI/API capabilities, order accuracy, on‑time shipments, inventory accuracy, dock‑to‑stock times, cost per pick/ship, and labor utilization. Ensure the provider can share actionable dashboards and supports integration with your OMS and carrier partners.

Negotiate clear fee structures for storage, handling, receiving, and returns; SLA‑linked penalties; minimums and scalability clauses; fuel and accessorial pass‑throughs; and visibility into labor and OT assumptions. Include regular cost‑to‑serve reviews to align incentives.

Assess the provider's client mix, expansion capacity, contingency plans for labor and transport disruptions, and onboarding process. Review references, run a pilot for a representative SKU set, and require performance milestones and exit terms to limit operational and financial risk as volumes grow.
