Systems, methods, and articles of manufacture for expense management are disclosed. A user may submit receipts for one or more transactions into an expense management system. The expense management system may extract information from the receipts and match the extracted information to one or more of a plurality of Records of Charge (ROCs). The expense management system may match the extracted information to a ROC based on vendor name, location, time stamp, and the like. The expense management system may further assign a ROC to an expense category. The expense management system may assign a ROC to an expense category based on a standard industrial classification (SIC) code of a merchant, a category assigned to a different ROC, and a location associated with the ROC. An expense report for all submitted receipts may be generated.
