Prioritize WMS integration (real-time API), pick-and-pack throughput, racking and cubic utilization, bonded customs handling, carrier connectivity, pick accuracy SLAs, scalable labor, and clear billing models. Verify physical security, loading dock capacity, and contingency plans for peak seasons and cross-border delays.

Closer proximity to major corridors shortens transit times and reduces carrier fuel and linehaul charges, improving lead times and delivery predictability. Robust carrier networks and multimodal options (truck/rail/intermodal) allow cost‑effective routing and better on‑time delivery performance for regional and cross‑border shipments.

A modern WMS with API connectivity, real‑time inventory synchronization, order orchestration, returns management, and reporting dashboards is essential. Look for EDI/API integrations with major carriers, marketplace connectors, and support for barcode/RFID scanning to ensure inventory accuracy and omnichannel order routing.

Request documentation of bonded status, customs broker partnerships, and recent audit records. Confirm experience handling duties, tariff classifications, and ISC/entry filing. Evaluate SLA clauses for customs delays, ask for references on cross‑border shipments, and verify insurance and security certifications relevant to bonded operations.
