Prioritize carrier connectivity (port and parcel networks), dock and staging capacity, racking and temp-control options, SLAs for pick/pack and transit, and the provider's OMS/WMS integrations. Also evaluate labor availability and seasonal scalability to maintain service during peaks.

Closer port and feeder access shortens vessel-to-shelf time, lowering buffer inventory needs and reducing demurrage or expedited shipping costs. This improves inventory turns and lowers total landed cost — especially for high-velocity SKUs and replenishment-driven B2B models.

Look for dedicated returns processing workflows, reverse-logistics staging, quality-inspection areas, and rapid restocking paths. Real-time returns visibility and integrations with order-management systems reduce cycle times and improve refund/exchange speed for customers.

Model fixed storage, receiving and put-away fees, pick/pack rates, cartons and materials, outbound parcel or freight costs, and value-added services. Include seasonal labor premiums, fuel surcharges, and the impact of service-level penalties on total fulfillment spend.
