Prioritize transit times to key customer zones, multi-carrier access (parcel + LTL), WMS/API capability for order orchestration, cross-dock and staging capacity, labor availability and shift flexibility, slotting and automation options, and local real estate and tax economics that affect long-term operating cost.

Model landed cost by combining outbound parcel/LTL rates, average transit days to core ZIPs, inventory carrying cost (safety stock), labor and facility rent, and inbound replenishment lanes. Run zone-skipping and network optimization scenarios to compare total delivered cost and service-level tradeoffs.

Require proven peak staffing plans, flexible storage and overflow options, same-day/next-day pick capabilities, integrated returns processing, real‑time WMS visibility and EDI/API connectivity, and KPIs for order accuracy and on-time ship rates tied to SLA penalties or credits.

Look for multiple parcel carriers with daily pickups and hub access, strong LTL coverage with lane density, proximity to intermodal or rail ramps if you use containers, and consolidation/cross-dock services. Negotiated access to regional carrier contracts can reduce rates and transit days.
