Evaluate highway and rail proximity (Federal Highway 45, intermodal links), airport access for air consolidations, number of dock doors, trailer parking and TL/LTL carrier coverage. Also review carrier lanes to border crossings, average transit times, and the 3PL’s carrier contract relationships and freight consolidation capabilities.

Aguascalientes City generally offers lower occupancy and labor costs than Mexico City and competitive rates within the Bajío region. Lower fixed operating expenses reduce per‑order warehousing charges and make value‑added services (kitting, light assembly) more cost‑effective while preserving margins for same‑day/next‑day eCommerce service levels.

Prioritize WMS integration and real‑time inventory visibility, pick‑and‑pack accuracy, configurable SLAs for same/next‑day shipping, returns processing and reverse logistics, plus value‑added services such as kitting and light assembly. Confirm 3PL ability to scale labor and seasonal capacity.

Require clear KPIs: order accuracy (%), on‑time in‑full (OTIF), inventory accuracy, dock‑to‑stock time, order cycle time and cost per order. Include chargeback thresholds, claims resolution timelines and regular operational reviews to ensure continuous improvement and scalability.
