Prioritize WMS interoperability (APIs/EDI), on-time-in-full (OTIF), order cycle time, pick accuracy, and dock-to-stock velocity. Also assess reporting cadence, SLA penalties, and ability to support ASN, batch tracking, and return processing to align fulfillment performance with customer expectations.

Carrier density and multimodal links directly affect transit windows and routing flexibility. Proximity to major highways, regional freight hubs, and feeder services enables zone skipping, consolidated LTL lanes, and lower linehaul rates—reducing transit times and total landed cost for domestic and export flows.

Key cost drivers include storage and handling rates, inbound receiving fees, pick-and-pack charges, minimums, fuel and accessorial surcharges, and demurrage. Negotiate volume tiers, transparent rate cards, and SLA-based credits to align costs with throughput and margin targets.

Evaluate available labor pool, seasonal temp staffing plans, recruitment lead times, training programs, and automation options. Confirm provider ramp-up history, contingency plans for labor disruptions, and real examples of scalable throughput during peak events to validate readiness.
