Evaluate network coverage, WMS and API integration, pick/pack accuracy, SLA definitions, reverse logistics capability, value‑add services (kitting, labeling), labor model and scalability, and carrier partnerships. Prioritize measurable KPIs and a clear onboarding plan to align inventory visibility and order cycle requirements.

Proximity to highways, rail spurs, and nearby ports/air gateways reduces linehaul mileage and last‑mile zones, lowering freight spend and transit days. High carrier density increases rate competition and route flexibility, improving delivery predictability and reducing risk of carrier capacity shortfalls.

Require real‑time WMS integrations (API/EDI), inventory reconciliation cadence, order cut‑off times, SLA targets for pick/pack accuracy and ship time, and standardized reporting. Request audit trails for receipts and returns and demonstration of failover processes for peak volume.

Request a detailed activity‑based quote that separates receiving, storage, pick/pack, pallet handling, packaging, returns processing, and value‑add services. Ask for examples of monthly billings, penalty/chargeback policies, minimums, and how demurrage or detention is applied to avoid surprises.
