Prioritize proximity to major highways, last-mile carrier coverage, throughput capacity (dock doors, conveyors), storage density (racking & mezzanine), SLA guarantees for pick/pack/ship, and WMS/API integrations. Validate labor availability and local operating costs versus service-level targets before contracting.

Request API documentation, live tracking samples, and proof-of-performance metrics (on-time delivery, transit variance). Audit returns workflow, RMA throughput, and partner SLAs. Run a pilot SKU program to measure actual last-mile lead times and return-to-stock cycle times against KPIs.

Assess clear height, floor load rating, number of dock doors, staging and cross-dock areas, heavy-duty racking, MHE fleet, and security systems. Confirm space for value-add operations (kitting, labeling), staging lanes for LTL consolidation, and access to reliable carrier networks for outbound distribution.

Key cost drivers include storage rates (per pallet/day), labor and handling fees, fuel and transport surcharges, pick/pack complexity, and minimum monthly volumes. Model scenarios using order velocity, SKU dimensions, and carrier zone rates to compare total landed cost versus desired transit times and return rates.
