Prioritize WMS compatibility and real-time visibility, throughput and peak capacity, SLA-backed pick/pack and shipping times, returns handling and reverse logistics capability, and value-added services (kitting, bundling, temp control). Also validate carrier integrations and on-site labor flexibility to support peak season scaling.

Proximity to major highways and rail nodes reduces last-mile miles and transit time, which lowers parcel and LTL costs. Sites closer to primary corridors provide better carrier density and routing options, improving delivered costs and reliability for both domestic distribution and cross-border movements.

Look for configurable racked storage, multi-temperature zones, dedicated pick/pack lines, cross-dock capability, returns processing, and space for kitting and light assembly. Integration-ready WMS/WCS and proven EDI/API connections to marketplaces and carriers are equally important for omnichannel orchestration.

Negotiate transparent unitized and accessorial pricing, minimum volume flex, clear SLA definitions with chargebacks, inventory accuracy and shrinkage clauses, service credits, lead-time commitments, and audit/exit rights. Include KPIs for on-time shipping, order accuracy, and inventory reconciliation cadence.
