Prioritize measurable KPIs (on-time shipments, inventory accuracy), WMS/ERP integrations, SLA terms, slotting and pick-path efficiency, minimums and billing structure, and available value-added services (kitting, returns, labeling). Evaluate carrier access and transit times to your customer base to confirm the site meets cost-to-serve targets.

Location near major highways and freight corridors reduces road transit windows and provides multiple carrier choices for both LTL and parcel. Proximity to multimodal terminals can enable competitive rates and routing flexibility, shortening delivery windows for regional markets and improving service consistency for next-day or two-day promises.

Typical onboarding ranges from 6–12 weeks depending on complexity. Simple SKU sets and standard EDI/API integrations can complete in 4–6 weeks; complex assortments, custom packing, or deep WMS/OMS customizations may require 8–12+ weeks and phased cutovers to maintain continuity.

Request operational metrics, client references, and a site tour or virtual walkthrough demonstrating kitting lines, returns workflows, and peak staffing plans. Review contingency plans for labor and carrier disruptions, and confirm WMS rules for returns disposition, batch kitting, and SLA adjustments during seasonal surges.

Common cost items include inbound receiving fees, storage per pallet/cubic foot, pick-and-pack charges (per pick or per order), outbound handling, special packaging, returns processing, and monthly minimums. Confirm billing granularity, passthrough carrier rates, chargeback policies, and any seasonal or peak surcharges.
