Evaluate carrier reach and transit times, inventory visibility (WMS capabilities), order accuracy and pick/pack SLAs, cold‑chain or special handling if needed, and the provider’s capacity to scale during peaks. Also review returns processing and value‑added services such as kitting or light assembly.

Regional highway connectivity affects linehaul cost and delivery windows; closer feeder links reduce last‑mile expenses. Access to reliable local carriers and national courier networks improves predictability, while multimodal options lower cost for bulk shipments to central hubs.

Prioritize WMS integration (real‑time inventory), pick/pack accuracy, same‑day or next‑day fulfillment capabilities, returns handling, and compliance with temperature control if required. Standard SLAs to confirm include order accuracy, on‑time dispatch, and inventory reconciliation cadence.

Negotiate transparent rate cards for storage, handling, and value‑added services; volume tiers and review periods; minimums and peak capacity clauses; lead times for scaling lanes; and penalties or credits tied to SLA performance to align incentives.
