Prioritize pick/pack accuracy, slotting and inventory management, multichannel order routing, returns processing, and IT integration (EDI/API/WMS). Also evaluate throughput capacity, seasonal scalability, and value‑added services like kitting and light assembly to match SKU complexity and demand variability.

Transit times drive shipping zone distribution and parcel costs; denser carrier access enables more negotiated rates and service choices. Assess regional carrier lanes, consolidation opportunities, and last‑mile density to balance speed versus landed cost for target customer geographies.

Evaluate warehouse layout flexibility, clear heights, dock counts, labor market strength, and local wage trends. Confirm the provider’s automation roadmap (sortation, WMS, voice picking) and ability to scale space and headcount for peak demand without service degradation.

Include KPIs for order accuracy, on‑time shipping, picking productivity, inventory reconciliation timelines, chargeback rules, and latency for WMS/API updates. Define dispute resolution, audit rights, and ramp milestones to ensure operational transparency and predictable service levels.
