Focus on transit times to core customer zones, carrier pickup frequency, WMS and API compatibility, inventory accuracy SLAs, returns and reverse logistics capabilities, value‑added service options (kitting, personalization) and scalability for peak seasons. Also review contract flexibility and KPIs tied to chargebacks and service levels.

Look for cross‑dock and staging capacity, dock density, pallet racking and mezzanine space, refrigeration when needed, integrated TMS/WMS, EDI connectivity, documented SOPs for ASN/PO management, and experience handling DSD, palletized loads and appointment scheduling with carrier partners.

Assess total landed cost: combine per‑pallet or per‑order warehousing fees with last‑mile shipping savings, carrier discounts and stock‑out risk. Proximity can cut transit times and freight spend, but higher rents may be offset by lower transportation and improved customer service metrics. Model scenarios for typical order profiles and peak volume to decide.
