Prioritize carrier frequency and modal options, demonstrated seasonal capacity management, WMS/OMS integration and reporting, physical infrastructure (dock doors, lift capacity, racking), cold‑chain capability if needed, security and insurance coverage, SLA commitments (pick/pack accuracy, lead times), and references for similar northbound distribution profiles.

Seasonal road windows and river barging create variable transit times; plan by pre‑positioning inventory ahead of peak seasons, increasing safety stock for critical SKUs, and coordinating consolidated shipments around barge/road schedules. Expect higher reliance on air or expedited trucking during constrained months, which affects cost and lead‑time modeling.

Require temperature‑controlled zones with continuous monitoring, documented HACCP or equivalent processes if applicable, reliable backup power, secure storage areas, tamper‑evident handling procedures, documented chain‑of‑custody, and appropriate insurance and audit capabilities to protect high‑value or perishable inventory.

Compare line‑item pricing for inbound receiving, storage (by cubic/board feet and tiers), pick/pack, outbound freight and fuel surcharges, minimum monthly fees, peak season surcharges, and ancillary services (kitting, returns). Scrutinize lead‑time penalties, indexation clauses, notice periods for rate changes, and measurable KPIs tied to performance and liability.
