Prioritize SLA performance (pick/pack speed, cut‑off times), OMS/WMS integration, pick density and slotting flexibility, dock and staging capacity, outbound carrier mix, and contingency plans for peak season labor. Also review contract terms for minimums, chargebacks, and inventory reconciliation cadence to align cost with expected order profiles.

Proximity to Highway 4 and coastal feeder routes reduces overland miles to southern destinations, which can shorten transit windows and lower fuel and line‑haul charges. For exports, choose 3PLs with established port feeder connections and consolidated LCL/LTL programs to optimize modal mix and reduce per‑unit ocean or feeder costs.

Verify clear yard and trailer parking, dock count and levelers, racking clearance, bulk and pallet positions, temperature control if required, IT interfaces (EDI/API), security and compliance certifications, and demonstrated throughput for similar SKU velocity to validate capacity and operational resilience.

Negotiate tiered pricing by volume, flexible minimums during off‑peak months, bundled inbound consolidation, shared labor pools for peak surges, and performance‑based rebates tied to fulfillment KPIs. Clarify accessorials, demurrage, and inventory holding fees to avoid unexpected cost escalation.
