Prioritize port proximity, dock and container handling capacity, WMS compatibility and EDI/APIs, cold-chain certifications if needed, SLA terms for picking and shipping, and demonstrated throughput for your channel mix. Also assess labor availability and contingency plans for peak seasons.

Port-on-dock access shortens ship-to-warehouse transfer times and reduces drayage costs. Strong highway and rail links lower inland transport costs and lead times, enabling consolidated shipments and faster replenishment cycles—directly improving total landed cost and service reliability.

Key capabilities include real-time WMS with marketplace integrations, pick-and-pack efficiency for small orders, returns processing, temperature-controlled storage, value‑add kitting, inventory visibility, and scalable labor models to handle peaks without sacrificing SLA compliance.

Compare total cost-to-serve (storage, handling, receiving, returns), minimums and volume tiers, SLA penalties, throughput metrics, and real-world examples of seasonal scaling. Request site tours, reference checks, and sample KPI reports (OTD, accuracy, dwell time) before contracting.
