The present disclosure includes a system for expense management. The method may include authenticating a user to a user account, retrieving a unique id (GUID) associated with the user, receiving (from a user device associated with the user) a digital copy of a receipt, and associating the digital copy of the receipt with the GUID. The method may further comprise requesting a record of charge (ROC) associated with the GUID, receiving a record of charge (ROC) associated with a GUID, and/or matching, by the computer-based system, the image of the receipt to the ROC based upon the GUID and information acquired from the digital copy of the receipt.
