Prioritize order accuracy, on-time order fulfillment, dock and throughput capacity, average pick rates, storage density (racking and mezzanine availability), receiving turnaround, and systems compatibility (WMS/ERP/OMS APIs). Also assess seasonal staffing plans, contingency capacity for peaks, and clear SLAs tied to chargebacks and service credits.

Cochrane 3PLs often yield lower real estate and operating costs and faster delivery to nearby regional customers, while transit times to distant metros can be longer. Evaluate actual transit-time maps for your carrier mix and lanes, and consider multi-node networks or cross-docking to preserve national lead times.

Require a modern WMS with API/EDI connectivity, real-time inventory visibility, multi-channel order routing, kitting and bundling, automated returns processing, lot/serial tracking where applicable, and reporting/analytics. Confirm integration tests and a documented onboarding timeline for SKU setup and EDI/API connections.

Common elements include storage rates, pick/pack fees, receiving charges, minimums, accessorials, billing cadence, and ramp or volume commitments. Negotiate clear SLAs for OTIF, order accuracy, inventory reconciliation cadence, liability for loss/damage, termination notice, and defined chargeback conditions to avoid unexpected costs.
