Prioritize measurable KPIs and integrations: order accuracy, OTIF (on-time in-full), average lead time, and pick/pack throughput. Require real-time WMS visibility and API connectivity to carriers and your storefront. Confirm returns-processing timelines, inventory reconciliation cadence, and scheduled operational reviews to keep SLAs aligned with peak demand.

Transport economics hinge on distance to main routes, frequency of carrier runs, and consolidation opportunities. Expect lower real estate and labor costs but model LTL lane rates, terminal handling and fuel surcharges. Optimizing shipment consolidation and pickup schedules from Chumbicha typically yields the greatest per-unit savings.

Negotiate clear SLAs for order turnaround, inventory accuracy and returns processing; define minimum volumes, surge capacity fees and notice periods for seasonality. Require segregation of inventory, transparent fee schedules, regular reporting, and insurance/ liability terms to protect product value and preserve service continuity during peaks.
