Prioritize warehouse footprint and racking density, number of loading docks and throughput capacity, WMS and API connectivity, slotting and pick density, value‑added services (kitting, returns), clear SLAs for accuracy and lead times, plus security, utilities uptime, and availability of trained labor for peak seasons.

Proximate carrier access reduces drayage and linehaul spend while shortening door‑to‑door times. Reliable cross‑border corridors enable consolidation and scheduled departures that lower per‑unit rates. Evaluate modal options, border processing cadence, and carrier density to quantify transit variability and routing flexibility.

Require real‑time WMS integration (APIs/EDI), documented SLAs for order cutoffs and accuracy, regular cycle counting, and transparent reporting. Ask for returns processing, light assembly/kitting, and rapid pick/pack options where available, plus clear escalation and penalty terms.

Model total landed cost including occupancy, handling fees, inbound/outbound transport, duties, inventory carrying, and shrinkage. Run scenarios for demand variability, include SLA risk, and validate assumptions with a pilot volume to measure real throughput, transit times, and true cost differentials before long‑term commitments.
