Prioritize geographic fit to customer demand, throughput capacity, SLA guarantees (order cutoffs, TAT), inventory accuracy, WMS/API integration, returns handling, and transparent cost models. Verify peak handling capacity and contingency plans for carrier disruptions before contracting.

Warehouse location determines proximity to major highways, rail terminals and last‑mile hubs, directly affecting transit time and freight cost. A well‑placed facility reduces miles, enables access to multiple carriers, and improves delivery windows for both B2B and consumer shipments.

Compare storage by pallet and SKU, inbound receiving fees, pick‑and‑pack and cartonization charges, outbound freight pass‑throughs, minimums, seasonal labor surcharges, and fees for value‑added services. Request a total landed cost model based on projected volumes and SKU mix.

Validate WMS/ERP integrations (API/EDI), complete end‑to‑end test orders, confirm inventory accuracy, agree KPIs and penalties, establish SOPs for exceptions, and run pilot volumes. Schedule training for both teams and a defined rollback/contingency plan for early issues.
