Assess SLA performance (order lead times, accuracy), technology compatibility (WMS/OMS APIs), facility capabilities (storage density, temperature control, kitting), scalability for peaks, billing transparency (pick/pack, storage, handling), and carrier relationships that influence parcel zones and freight costs.

Look for proximity to interstate corridors and intermodal terminals that shorten transit lanes, high carrier density for competitive rates, regional airports for expedited shipments, and cross-docking to minimize dwell time and lower distribution costs.

Calculate inbound freight, storage (per-pallet/cubic), pick-and-pack fees, outbound parcel or LTL zones, and reverse logistics. Model inventory velocity and safety stock by SKU to compare cost-per-order and delivery time trade-offs across candidate locations.

Require a modern WMS with API/EDI connectivity to your OMS and ecommerce platforms, real-time inventory visibility, shipment tracking, exception alerts, and standardized KPIs (OTD, order accuracy, dwell). Ensure access to custom reporting and business reviews for continuous optimization.
