Prioritize carrier reach and highway access, warehouse footprint and scalability, technology for inventory visibility (WMS/APIs), pick-and-pack accuracy, and value-added service capabilities. Also evaluate customs brokerage support for cross-border shipments and metrics for lead time, order accuracy, and cost per order.

A Tartagal 3PL can reduce overland transit time to neighboring markets and offer consolidation to lower per-unit costs. Key considerations include the provider's customs experience, bonded storage options, local carrier contracts, and documented processes for duties, documentation, and transit insurance.

Compare real estate rent, local labor rates, inbound/outbound transport costs, last-mile delivery options, inventory carrying costs, and value-added service fees. Factor in potential savings from shorter regional hauls, offset by any longer legs to national consumption centers.

Negotiate SLAs for order lead time, on-time shipment rate, pick-and-pack accuracy, returns processing time, inventory accuracy, and penalty structures for missed KPIs. Include reporting cadence, system integration requirements, and escalation procedures.

Assess the 3PL's flexible labor pools, temporary space expansion plans, seasonal throughput history, technology for workload forecasting, and partnerships with local carriers. Request capacity planning examples and references demonstrating peak-season performance.
