Require clear KPIs: order cycle time, pick/pack accuracy, on-time shipments, inventory accuracy, and dock-to-door lead times. Ask for historical SLA performance, chargeback policies, and reporting cadence so you can measure carrier handoffs, returns processing, and continuous improvement.

Prioritize dock door count and layout, pallet racking density, clear height, temperature control, and cross-dock capacity. Verify local carrier networks, road access to main routes, consolidation services, and proximity to distribution hubs to minimize transit times and handling.

Negotiate storage and pick/pack pricing, accessorial fees, minimums, billing frequency, and volume tiers. Include SLA credits, termination clauses, onboarding timelines, and inventory reconciliation processes to limit unexpected charges and align incentives.

Require robust WMS and API/EDI integration with your OMS, defined RMA and returns flows, and real-time inventory feeds. Confirm support for lot/serial tracking, barcode standards, and SLA-triggered reporting to maintain accurate stock levels and fast return-to-stock cycles.
