Prioritize carrier connectivity to U.S. gateways, experience with customs and bonded programs, WMS and API integrations for marketplace/parcel carriers, pick-and-pack scalability, returns processing, and proven SLA adherence. These factors reduce transit time, avoid clearance delays and support consistent customer experience.

Coahuila often offers lower real estate and labor rates than U.S. border metros, which can reduce storage and handling expenses. However, total landed cost also depends on drayage to U.S. gateways, customs duties, inventory carrying and service fees—model scenarios for SKU velocity and routing to quantify net savings.

Expect full truckload and LTL highway services, interline rail connections to U.S. railheads, regional air cargo options via nearby airports, and parcel networks offering last-mile cross-border solutions. Effective 3PLs coordinate multimodal routing and carrier selection to optimize cost and transit time.

Evaluate financial stability, facility certifications, insurance, technology stack (WMS/TMS/API), sample SLA terms, security and compliance practices, and references. Monitor KPIs such as inventory accuracy, order cycle time, on-time delivery, dock-to-delivery lead time and return resolution rates to ensure operational alignment.
