Prioritize carrier network density and multimodal connections, SLA-backed inventory visibility (WMS integration), scalable throughput, returns management, and clear cost-to-serve reporting. Also assess the 3PL's experience with seasonal volume swings and local regulatory or customs handling.

Closer placement to southern demand zones reduces last-mile distance and transit time, enabling lower parcel and LTL costs. Strategic inventory splits between central hubs and a local Esquel node can optimize lead times and lower overall logistics spend by reducing expedited shipments.

Require a modern WMS with API integrations, pick-and-pack and B2B pallet handling, returns processing, value-added services (kitting, labeling), temperature-controlled options if needed, and reliable carrier partnerships for predictable distribution across channels.

Consider regional labor rates and availability, seasonal labor fluctuations, utility and handling costs, local taxes or incentives, property expansion options, and the 3PL's ability to offer variable-cost models tied to throughput to mitigate fixed-cost exposure.
