Evaluate transit times to primary customer zones, carrier network integrations (parcel, LTL, regional trucking), warehouse layout for pick/pack efficiency, available value‑added services (kitting, returns processing), and SLAs for order accuracy and same/next‑day picks.

Location influences trucking miles, fuel and driver costs, and lead time variability. Warehouses nearer major highways reduce transit time and carrier charges, while peripheral sites often offer lower rent and labor costs but slightly longer delivery windows—balance placement against service targets and parcel carrier zones.

Look for validated cold-chain infrastructure, monitored temperature controls with alarms, secure storage areas, inventory visibility and audit trails, ISO or industry‑specific certifications, and documented SOPs for handling, sampling, and traceability.

Negotiate transparent fee schedules (storage, handling, pick/pack, kitting), volume and seasonal rate flex, minimums, liability and insurance terms, performance-based SLAs with rebates or penalties, and clear exit provisions to avoid switching costs.
