Prioritize pick-and-pack accuracy, dock-door count and throughput, receiving and putaway SLA, racking density, available cube, and cold-storage capacity. Check security, insurance, and KPI reporting (OTD, inventory accuracy, pick error rate) to align performance with your SLAs and cost targets.

Evaluate storage-by-cubic-meter or pallet, per-pick/per-line pick-and-pack fees, inbound receiving charges, handling for returns, and value-added services. Factor transportation rates, fuel surcharges, and minimums into landed-cost models and request sample invoices to forecast margin impact accurately.

Expect competitive regional transit via the Pan-American Highway with reliable trucking corridors to Pacific ports and airport gateways. Transit times are typically shorter for inland distribution versus routing through central metro hubs, but confirm scheduled departures, consolidation options, and last-mile coverage with prospective 3PLs.

Critical. Real-time inventory visibility, order routing, and automated shipping tendering reduce errors and speed fulfillment. Look for WMS with API/EDI connectivity to your storefronts and carriers, configurable workflows for returns, and reporting that supports continuous improvement and inventory reconciliation.
