Prioritize WMS integration (real-time inventory and order APIs), scalable pick-and-pack capacity, returns processing, kitting/assembly, temperature control if needed, and measured KPIs (pick accuracy, on-time shipping). Also evaluate ramp-up speed for peak seasons, IT support for EDI/API, and visibility tools for customers and carriers.

Proximity to key corridors reduces transit time and handling, lowering freight spend and damage risk. Strong carrier access and dedicated lanes decrease variability and enable tighter SLAs. Evaluate hub-to-market transit times, intermodal options, and average carrier dwell to model landed costs and promised delivery windows.

Negotiate clear KPIs (OTD, pick/pack accuracy, inventory accuracy), chargeback thresholds, minimum volume commitments, seasonal capacity clauses, rate review periods, and termination terms. Ensure transparency on storage tiers, inbound/outbound handling, special services, and technology fees to align cost-to-serve with expected volumes.
