Provided herein are systems, methods and computer readable media for identifying supply. An example for identifying merchants for fulfilling demand comprises receiving one or more virtual offers and an associated quantity of at least a portion of the one or more virtual offers, wherein the one or more virtual offers are representative of a residual demand for a geographic area, assigning a virtual offer of the one or more of the virtual offers to one or more merchants in an instance in which a supply source of the one or more merchants is identified as able to supply at least a portion of the associated quantity of the virtual offer, and determining a priority score for the one or more merchants, wherein the one or more merchants are rankable based on the priority score.
