Prioritize WMS compatibility, temperature control if needed, cross-dock capacity, slotting and pick-path optimization, and proven carrier integrations. Also confirm SLA metrics for pick accuracy, order cycle time, and peak-season scalability.

Carrier density and modal access shape transit times and freight rates. Closer proximity to highways, feeder ports, and regional carriers reduces last-mile costs and improves delivery windows, directly lowering landed cost and improving customer SLAs.

Evaluate storage rent and billing periods, receiving charges, pick-and-pack rates, minimums, dimensional weight rules, returns processing fees, and any value-added service charges. Ask for sample invoices and a modeled cost-to-serve for your SKU mix.

Typical onboarding ranges from 4–12 weeks depending on integration complexity. Expect initial EDI/API setup, test orders, SOP development, pilot shipments, and staff training. Build time for custom rules, labeling, and vendor compliance into the schedule.
