Assess throughput and SKU mix, required handling (temperature control, returns, kitting), slotting and labor models, and WMS/TMS integration. Compare transparent pricing (storage, pick/pack, cross-dock), SLA definitions, onboarding timelines and historical KPIs to estimate total landed fulfillment cost.

Trade-offs include lower rent versus higher outbound freight if further from customer clusters, labor cost variations, state/local incentives, and inventory carrying costs driven by safety stock. Balance proximity to carriers and customers with facility operating rates and throughput efficiency.

Use distributed inventory across regional DCs or micro-fulfillment, leverage multiple parcel and courier contracts for zone-optimized routing, require real-time visibility and exception management, and validate same-day or next-day capabilities during peak volumes through testing and seasonal SLAs.

Define on-time shipment rate, order accuracy, inventory accuracy, dock-to-stock timing, pick/pack productivity, claim resolution time, carrier tender acceptance and chargeback thresholds. Include regular reporting cadence and remediation steps tied to financial consequences for missed SLAs.
