Focus on carrier connectivity, transit lanes to major markets, and WMS/API interoperability for real‑time inventory. Evaluate dock configuration, racking, temperature control, value‑add services (kitting, labeling), SLA metrics for order accuracy and cycle time, and contingency plans for peak season staffing and carrier disruptions.

Compare storage tiers, handling fees, inbound/outbound consolidation options, and zone‑based shipping impacts. Model inventory placement vs. order density, assess zone‑skipping potential from port and road links, and include returns processing costs to get a complete per‑order landed cost evaluation.

Require real‑time API or EDI order/ASN flows, barcode scan traceability, lot/batch and expiry management if relevant, automated replenishment triggers, standard reporting, and compatibility with your OMS/ERP. Confirm support for batch uploads, scheduled EDI windows, and exception management workflows.

Carrier density affects LTL frequency and linehaul reliability; proximity to port and trunk roads reduces transit variability. Last‑mile partnerships determine consumer delivery windows. Seasonal labor pools and 3PL workforce planning influence order cycle times—verify peak staffing strategies, temp labor agreements, and backup carrier options to protect SLAs.
