Prioritize WMS and TMS integration, SLA definitions (order accuracy, OTIF), dock and throughput capacity, SKU velocity handling, returns processing, and surge scalability. Confirm visibility tools, EDI/API capabilities, security and compliance, and clarity on cost components (storage, handling, pick fees, and value‑adds).

Carrier density and direct lane options reduce transit time and enable freight consolidation. Strong highway and regional carrier access lowers LTL and parcel rates, shortens last‑mile distances, and increases routing options—translating to lower per‑unit shipping cost and improved delivery windows for both eCommerce and B2B flows.

Expect scalable labor pools, surge planning, flexible slotting, cross-dock and flow-through operations, pick-and-pack optimization, kitting and light assembly, returns processing, and temperature-controlled storage when required. Also confirm real-time reporting and exception management for peak visibility.

Include inventory accuracy, order accuracy, OTIF, average pick-to-ship time, dock-to-stock lead time, SLA penalties for noncompliance, chargeback rules, billing audit cadence, and reporting frequency. These KPIs preserve service levels and enable continuous improvement.
