Prioritize multimodal connectivity (river and road), proven carrier interfaces, accurate inventory visibility (WMS/API), scalable labor/space availability for peaks, and defined service-level metrics (order accuracy, cut-off times, lead-time guarantees). Evaluate proofs of concept and references in similar trade lanes.

Seasonal access can alter transit times and capacity. Assess a 3PL's contingency routing, multimodal options, buffer stock policies, and contractual SLAs for delays. Confirm local carrier partnerships and planned seasonal capacity expansions to avoid service disruptions.

Yes, many regional 3PLs provide mixed fulfillment models: pick-and-pack, batch processing, cross-docking, kitting, and returns handling. Verify pick accuracy rates, parcel carrier integrations, batch sizes supported, and the ability to segment inventory by channel to meet differing service-levels.

Negotiate transparent rate cards (storage per pallet/CY, picking, handling, packaging), minimums, volume discounts, and clearly defined accessorial fees. Include KPI-based rebates or penalties, regular rate review clauses, and defined exit/transition terms to control long-term cost exposure.
