Require demonstrated inventory accuracy, scalable pick-and-pack capacity, cross-dock and batch-picking workflows, temperature-controlled zones if needed, and transparent WMS integrations with real-time inventory and order visibility. Evaluate proof of carrier integrations and SLA-driven cutoffs for same- or next-day dispatch.

Feeder frequency and port berth availability directly influence lead times; limited sailings increase buffer stock requirements and freight premiums. Assess scheduled feeder rotations, typical dwell times at terminal, and local carrier consolidation options to model true door-to-door transit and landed cost.

Focus on inventory accuracy, order cycle time, on-time-shipment rate, order fill rate, cost-per-order and cost-per-pallet, average dwell time, and exception/return handling metrics. Also request baseline throughput and peak-season scalability data to validate the provider’s capacity claims.
