Look for a provider offering racked storage, temperature‑controlled spaces, cross‑dock areas, scalable labor, and a modern WMS with carrier integrations. Consider demonstrated peak handling, returns processing, and parcel/last‑mile partnerships to handle spikes and omnichannel returns efficiently.

Map required delivery zones, measure actual trunk and last‑mile lead times from candidate sites, and verify carrier contracts. Request lane‑specific transit data, on‑time performance history, and consolidation schedules to validate regional coverage and predictability.

Compare fixed (rent, slotting) and variable (picking, packing, inbound/outbound handling) fees plus storage, special handling, and transport surcharges. Ask for sample monthly scenarios, minimums, and volume band pricing to model total landed fulfillment cost.

Include measurable SLAs for order accuracy, on‑time shipments, pick lead time, inventory accuracy, and returns processing. Consider credit/penalty terms tied to performance, regular reporting cadence, and agreed audit/inspection rights to maintain service levels.
