Prioritize WMS integration, SKU slotting and storage density, pick‑pack throughput, accuracy SLAs, inbound/outbound dock capacity, and value‑added services (kitting/returns). Also assess carrier access, transit times to key markets, labor availability, and visibility tools for order tracking.

Close port and airport access reduces last‑mile trucking and handling time, enabling shorter lead times and lower freight premiums on express lanes. It also supports consolidation strategies that lower per‑unit ocean/air cost and decreases inventory days‑in‑transit, improving working capital.

Require a modern WMS with API connectivity, order orchestration for channel splitting, real‑time inventory visibility, scalable labor scheduling, automated labeling/EDI, and a defined SLA for returns processing and inspection to minimize lead times and recovery cost.

Model fixed vs variable storage charges, pick/pack labor rates, inbound receiving fees, cross‑dock and last‑mile transport, value‑added services, inventory carrying costs, peak season surcharges, and any customs or bonded storage fees to calculate true cost‑to‑serve.
