Stored inventory onboard self-contained mobile storefronts are delivered with respect to an order and delivery system deployed over a regional delivery area operating in a closed network. A mobile storefront that receives an order from a consumer operates autonomously to facilitate preparation of the order from an aggregation of inventory stored thereon, then completes delivery to the consumer at the consumer's geolocation. A highly responsive on-demand system is provided that consolidates order fulfillment technologies to service consumers more quickly and efficiently by minimizing opportunities for human error.
