Request specific KPIs: order accuracy, pick‑pack cycle time, dock-to-door lead time, inventory accuracy, and on‑time shipment rate. Also evaluate carrier mix, peak capacity handling, and systems integration (WMS/ERP APIs) to ensure SLAs are enforceable and measurable.

Location determines miles driven, transit tiers, and access to major carriers—closer proximity to urban centers reduces last‑mile costs and delivery windows. Consider distribution center placement relative to customer density and carrier hubs to balance cost and speed.

Prioritize a modern WMS with real‑time inventory updates, API connectivity for storefronts and ERPs, event notifications (EDI/JSON), and reporting dashboards. Confirm support for batch processing, returns, and multi‑channel routing rules to avoid manual reconciliations.

Negotiate transparent fee schedules covering storage tiers, pick/pack rates, inbound handling, and accessorials. Include volume tiers, minimum performance SLAs, review windows for rate adjustments, and exit terms to retain flexibility as demand shifts.

Ask for historical peak performance data, seasonal staffing plans, temporary storage options, and contingency carrier arrangements. Validate cross‑training practices, surge staffing agreements, and lead times for expanding allocated slotting or pallet positions.
