Prioritize clear SLAs (OTD, pick accuracy), WMS/API integrations, scalable storage (racking and bulk), returns and kitting capabilities, labor skill levels, and contingency for peak volume. Verify carrier lanes and transit time reports to core markets before contracting.

Site proximity to main arterial roads and transshipment points reduces drayage and door‑to‑door times. Closer locations improve carrier density and negotiating leverage on rates, lowering per‑order transport cost for regional and cross‑border deliveries.

Require a WMS with real‑time inventory, EDI/API carrier integrations, order management support for split or multi‑channel orders, batch/lot tracking, and transparent reporting dashboards to monitor fill rates and cycle times.

Negotiate scalable space clauses, clear peak season tarifs, performance SLAs with financial penalties, defined inventory reconciliation cadence, and defined returns processing workflows to protect inventory accuracy and service continuity during spikes.
