Prioritize WMS functionality and API/EDI connectivity, pick/pack and cross‑dock throughput, inventory accuracy SLAs, returns and reverse logistics handling, and reporting cadence. Confirm carrier integrations, peak season scalability, and contingency plans for disruptions to ensure consistent service levels.

Placing inventory in the region reduces line‑haul distances to surrounding metros and enables faster last‑mile delivery windows. A 3PL with multi‑carrier access and regional cross‑docking can lower transit variability and improve delivery predictability across both eCommerce and B2B networks.

Key cost drivers include storage density (pallet vs. racked), labor rates and shift requirements, inbound handling and cross‑dock fees, pick/pack pricing and minimums, technology or integration fees, and accessorials such as returns processing or special packaging.

Request operational KPIs (OTD, inventory accuracy, order cycle times), visit facilities to observe throughput and storage practices, verify insurance and compliance certifications, check carrier and parcel integrations, and run a pilot SKU set to validate SLAs before full scale migration.

Confirm flexible labor pools, temporary racking or overflow space, surge pricing models, forecast sharing and demand planning processes, and the 3PL’s ability to onboard additional SKUs or promotional packaging quickly. Clear escalation paths and contingency plans are essential for peak reliability.
