Cash transaction entry data indicating a consumer has conducted a cash transaction with an unidentified merchant payee is obtained and geo-location data associated with the cash transaction data is used identify potential merchant payees of the cash transaction. If more than one potential merchant payee is identified, data representing the potential merchant payees is analyzed using historical financial transaction data associated with the consumer, and/or products or services and operations data associated with the potential merchant payees, and/or historical financial transaction data associated with a community of consumers, including consumers other than the consumer, to generate a potential merchant payee probability score for each of the potential merchant payees. The potential merchant payee probability score for each of the potential merchant payees is then used to generate a prioritized potential merchant payee list for the cash transaction that includes at least one of the potential merchant payees.
