Prioritize service-level metrics (OTD, order accuracy), throughput capacity, slotting and pick-path efficiency, WMS integration and API support, inbound/outbound dock capacity, and SLAs for peak season scalability. Also assess inventory visibility, security, and returns handling to align with your channel mix.

Selecting a 3PL near major road or intermodal connections typically lowers last‑mile costs and reduces transit days. Evaluate carrier contracts, fuel and accessorials, zone optimization, and multi‑carrier pick-up frequency to quantify cost and time savings for both eCommerce and B2B lanes.

Look for a WMS with real‑time inventory, EDI/API connectivity, configurable pick‑pack/parcel workflows, returns processing, cross‑dock capability, and climate control if needed. Verify order batching, SLA reporting, and integration with your storefronts and ERP for seamless omnichannel execution.

Negotiate clear SLAs with financial remedies, transparent fee schedules for storage and handling, volume discounts, minimum term flexibility, performance-based KPIs, rate review windows, and detailed clauses for peak surcharges and dispute resolution.
