Key evaluation points include system integration, throughput capacity, SLA history, labor model, and geographic reach. Consider:

• WMS/API compatibility and real‑time inventory visibility
• Pick‑pack accuracy, throughput, and peak scalability
• Carrier access and lane performance to key customer markets

Prioritize hardened racking and mezzanine space, climate‑controlled areas if needed, secure receiving and QC zones, effective cross‑dock capability, and value‑add services such as kitting, batching, and returns processing. Confirm SLA tiers for order turnaround and exceptions handling.

Carrier density and lane reliability directly affect shipping costs and predictability. Shorter regional transit lanes lower freight spend and reduce buffer inventory needs; limited carrier options raise premium for expedited lanes. Align SLA targets to actual transit windows and available carrier schedules.

Expect onboarding steps for systems integration (EDI/API), standard operating procedures, KPI alignment, and inventory migration. Useful milestones: test transactions, pilot fulfillment runs, agreed SLA penalties/rebates, and a phased cutover plan to validate accuracy and capacity.
