Prioritize multimodal access (port/road/air), facility layout for your processes (bulk, pick-and-pack, cold storage), local labor pool stability, WMS/TMS integration capabilities, and value-added services such as kitting and returns. Also model transit times, carrier density, and landed-cost scenarios against demand zones to validate network fit.

Run comparative models that include real estate and labor rates, inbound consolidation and cross-dock options, carrier rates by lane, and parcel zone changes. Include inventory carrying costs, expected lead-time reductions, and potential for zone-skipping. Use sample SKUs and order profiles to quantify cost-per-order and days-to-delivery improvements.

Insist on a modern WMS with API connectivity, real-time inventory visibility, carrier-agnostic shipping interfaces, and support for EDI or marketplace integrations. Ensure capabilities for returns processing, lot/serial tracking, and configurable workflows for kitting, labeling, and temperature control if required.

Typical onboarding spans 8–16 weeks depending on SKU complexity and systems integration. Key phases include requirements definition, WMS/TMS integration and testing, SOP development, staff training, and pilot shipments. Plan contingency time for carrier certifications, compliance checks, and peak season validation.
