Prioritize multi-carrier shipping integrations, real-time WMS visibility, scalable pick-and-pack labor, bonded storage if importing, and reverse logistics for returns. Ensure SLA metrics for order accuracy, cut-off times, and throughput during peak periods align with your customer promise.

Closer proximity reduces drayage and inland transit time, lowers variability in lead times, and enables tighter delivery windows. That typically translates to lower landed cost, fewer stockouts, and simpler carrier consolidation for both ocean and regional distribution lanes.

Look for high-bay racking, clear-span floor plates, dedicated value-add stations (kitting, labeling), bonded and ambient storage zones, and a WMS that supports lot control, batch picking and SKU velocity reporting to optimize space and labor utilization.

Model landling costs (drayage, duty handling), storage per pallet/cubic meter, pick-and-pack and handling fees, monthly minimums, inbound receiving charges, returns processing, and software/API costs. Include sensitivity to peak season labor and carrier surcharge scenarios.

Evaluate the 3PL's carrier roster, contracted lane rates, frequency of regional departures, LTL and FTL capabilities, and partnerships for last-mile delivery. Confirm pickup cutoffs, transit maps and contingency plans for weather or port disruptions.
