Verify proximity to primary ports and airports, road quality to Castries and population centers, availability of bonded or customs-friendly storage, existing carrier contracts for regional lanes, and on-site loading facilities. Confirm lead-time projections and container handling capabilities to align with your import/export rhythms.

Use localized inventory placement to shorten last-mile routes, adopt cross-docking to reduce handling, consolidate inbound shipments for freight efficiency, and negotiate regional carrier rates through the 3PL. Combine accurate demand forecasting with dynamic replenishment to limit stockouts and expedite deliveries.

Require real-time inventory visibility (WMS/API), pick-and-pack and kitting services, SLA-backed order processing times, reverse logistics handling, and secure storage options. Evaluate scalability, labor arrangements, and the provider's experience with cross-border documentation and carrier integrations.

Assess local customs procedures, duties and VAT application, bonded warehouse options, inspection requirements, and import/export documentation timelines. Ensure the 3PL has compliance processes for manifests, certification handling, and coordinate with freight forwarders to prevent demurrage and clearance delays.
