Prioritize order turnaround (pick/pack lead times and cutoffs), receiving and QC throughput, WMS integration for inventory visibility, carrier and last‑mile coverage, and value‑added services such as kitting and returns. Also assess scalability, contingency plans for peaks, and audit access to operational KPIs.

Lower facility and labor rates reduce fixed per‑unit storage and handling costs, which can free budget for faster carrier choices. However, inland locations may require consolidated shipments or regional carrier contracts—so evaluate carrier density, transit frequency, and freight pooling options to maintain competitive lead times and rates.

Verify direct access to national highways, dock and trailer capacity, appointment systems, proximity to intermodal or rail feeders, and documented carrier performance. Confirm TMS/EDI capabilities for routing, freight visibility, and integration with your order-management systems to avoid blind spots in the network.

Negotiate transparent rate schedules (storage, handling, pick/pack), SLAs for order accuracy and on‑time shipment with remedies, minimum volume commitments, inventory reconciliation cadence, reporting frequency, and scalability clauses for peak seasons. Include audit rights and clear change‑order procedures to manage cost drift.
