Prioritize throughput (lines and orders per hour), picking accuracy, inventory accuracy, on-time shipments, returns processing, and surge capacity. Confirm WMS integrations (EDI/API), slotting, kitting, lot/serial tracking, and SLA remedies. Match provider KPIs to SKU velocity and peak demand forecasts.

Waukesha's proximity to major interstates and metro hubs shortens transit lanes into the Midwest, often reducing parcel zone progression and LTL mileage. That enables more favorable carrier rates, faster transit promises, and better access to regional carrier hubs for next-day or two-day service to large population centers.

Expect line-item fees: receiving, storage (per pallet/cubic), pick/pack, kitting, returns processing, and monthly minimums. Negotiate performance-based SLAs, tiered pricing for volume growth, transparent accessorials, and limited-term pilot periods with defined KPIs and service credits to align incentives.

Run a total landed-cost model comparing rent, labor, transit days, and carrier charges. Consider inventory segmentation (fast movers near customers; slow movers centralized), dual-node strategies, and scenario modeling for peak periods. Choose the configuration that minimizes overall cost-to-serve while meeting delivery SLAs.
