Prioritize transit network connectivity (ports, trucking lanes), accuracy and scalability of the WMS, labor availability and shift patterns, cost-per-pick and storage tiers, and SLA guarantees for order lead time and returns processing. Request site visit reports and carrier manifests to validate throughput assumptions.

Proximity to feeder services and trunk routes reduces drayage and inbound cycle time, while multiple carrier options enable competitive parcel rates and faster transit windows. Improved intermodal choices lower reliance on single carriers and reduce cost volatility during peak seasons.

Expect blended pricing: storage per pallet or cubic meter, pick-and-pack per order line, inbound handling per pallet, and value-added services billed hourly or per unit. Negotiate minimum term flexibility, indexed fuel/carrier surcharges, and clear SLA penalties for chargebacks or missed windows.

Validate WMS/API readiness, EDI or REST integration timelines, inventory accuracy, on-time ship rate, order cycle time, returns turnaround, and exception handling processes. Require regular scorecards and a detailed onboarding plan with cutover milestones.
