Prioritize multi-modal carrier access, WMS/API integration, SLA guarantees for order accuracy and cut-off times, bonded/customs services, returns handling workflows, and scalable staffing. Also verify carrier lane density and last-mile partners to ensure consistent transit times and cost predictability.

Cost savings matter but must be balanced with service fit: evaluate total landed cost (storage, handling, transportation), tech integration costs, and potential delays from limited carrier options. A slightly higher rate with robust WMS/API, reliable SLAs, and customs support can reduce overall supply‑chain cost and risk.

Yes—many 3PLs in the area offer bonded warehousing, transit documentation, and local customs brokerage. Confirm specific experience with target corridors, required documentation, transit times, and whether the provider handles duties, ATA carnets or transit regimes for your freight profile.

Require real-time inventory visibility (API/EDI), order-status reporting, pick‑pack accuracy rates, on-time shipment percentages, cut-off time adherence, returns processing SLAs, and scheduled KPI reviews. Ensure the 3PL provides secure data exchange and customizable reporting for forecasting and carrier reconciliation.
