Prioritize measurable KPIs and system compatibility: inventory accuracy, on-time order fulfillment, pick-and-pack accuracy, throughput capacity, and SLA enforcement. Verify WMS/ERP integrations, EDI/API connectivity, security controls, and workforce stability. Request performance reports and a sample operating-level agreement to benchmark providers.

Compare door-to-door transit times to primary markets, available carrier lanes, consolidation frequency, and last-mile partner presence. Assess scheduled pickup windows, carrier density, and typical delivery SLAs. Factor in seasonal variations and options for multi-carrier routing to avoid single-source risk.

Require features that match your product profile: sufficient dock doors, racked storage, bulk and pallet handling, temperature control if needed, cross-dock capability, and secure yard access for heavy vehicles. Confirm load/unload equipment, staging areas, and scale-up options for peak volumes.

Model scenarios including inbound receiving, storage (by cube and duration), pick-and-pack, packing materials, returns processing, and accessorials. Request detailed rate cards, minimums, billing cadence, and dispute processes. Build 12-month volume forecasts into negotiations and include performance-based fee adjustments.
