Evaluate on metrics: transit time to key zip codes, warehouse SLAs (pick/pack, cut-off times), inventory visibility (WMS/API), return handling, and carrier base. Prioritize partners offering transparent rate cards, scalable space, and direct connections with regional road carriers to control last-mile costs.

Key capabilities: bonded/customs-ready areas if cross-border trade applies, climate-controlled storage for perishables, SKU-level inventory tracking, value-added services (kitting, labeling), and proven pick/pack throughput to meet peak demand cycles.

Use multi-node inventory placement to shorten delivery lanes, negotiate blended carrier contracts, leverage local labor rates for order consolidation, and monitor dwell times to reduce storage fees. Frequent SLAs reviews and reporting help identify cost drivers quickly.

Confirm permits for freight handling and storage, CCTV and insurance coverages, local carrier partnerships for trunk and last-mile movements, and compliance with state transport rules. Ask for sample transit matrices and references for shipments similar to your profile.
