Prioritize inventory visibility (WMS integrations), transit times to core markets, SLA performance for order accuracy and cut-off times, returns handling capability, and cold-chain or special handling if needed. Also confirm carrier connectivity and contingency plans for inter-island disruptions.

Ask providers for lane-level rate comparisons, consolidation schedules, and historical on-time performance. Validate whether the 3PL offers negotiated carrier contracts, roll-up consolidation to main ports, and real-time shipment tracking to reduce small-parcel premiums.

Verify dock capacity, storage types (racked, bulk, temperature-controlled), handling equipment, security and compliance certifications, WMS/ERP integrations, labour scalability, and KPIs for receiving, putaway, and outbound processing.

Critical: choose a 3PL with API-based order, inventory, and tracking integrations that support real-time inventory visibility, automated order routing, and returns workflows. Confirm mapping of SKUs, order types, and cutoff rules to avoid operational friction.

Negotiate transparent pricing for storage, handling, pick-and-pack, and value-added services; index or cap fuel and carrier surcharges; define performance SLAs with penalties; agree on inventory reconciliation cadence and exit terms to minimize business disruption.
