Prioritize carrier density and transit rings, WMS/TMS integration capability, SLA history, slotting and cross‑dock flexibility, scalability of labor resources, and transparent cost‑to‑serve modeling. Validate inventory accuracy metrics and returns processing workflows to ensure consistent customer experience across channels.

Location determines ground transit rings and access to regional carriers; sites near major interstates and distribution corridors reduce last‑mile time and expand same‑day or next‑day delivery reach. Proximity to rail or air hubs increases multimodal options for expedited or consolidated freight.

Analyze storage density and slotting fees, inbound receiving and cross‑dock charges, pick‑and‑pack and value‑add labor rates, minimum monthly charges, billing for returns and exceptions, and estimated freight spend based on projected transit zones. Include tech integration and onboarding costs in total cost of ownership.

Require real‑time WMS connectivity, EDI/API order flow, carrier rate shopping, and reporting access. Validate KPIs such as pick accuracy, on‑time shipments, inventory accuracy, dock-to-stock times, and SLA adherence. Confirm security and compliance controls for regulated SKUs where applicable.
