Compare inventory accuracy, order lead time, pick-and-pack accuracy, OTIF (on-time in-full), and return processing time. Also assess IT integration (WMS/API), real-time visibility, penalty/bonus clauses in SLAs, and scheduled reporting cadence to align expectations with your channels.

Port and airport connectivity determine frequency of sailings and flights, consolidation options, and transshipment needs. Good feeder service reduces last-mile delays and freight legs; limited direct services often require hub transshipment, increasing lead time and per-shipment cost—plan consolidation and scheduled pick-ups accordingly.

Prioritize temperature-controlled storage, dedicated packing and returns areas, cross-docking, kitting/assembly, and fast pick-and-pack workflows. Evaluate capacity for peak season scaling, labeling/compliance services, and secure storage for high-value inventory to support diverse fulfillment models.

Negotiate tiered storage and handling rates by volume, reduced fees for longer-term storage density, consolidated carrier pickups, minimum-volume discounts, and shared labor pools. Define clear SLA incentives/penalties and review slotting and layout charges to improve space utilization and lower unit costs as volumes grow.
