A computer system can implement a network service by receiving, from a computing device of a user, image data comprising an image of a record. the computer system can then execute image processing logic to determine a first set of information items from the image, and identify a second set of information items that are not determinable from the record. The computer system may then execute augmentation logic to process the record by (i) accessing a transaction database to identify a plurality of transactions made by the user, (ii) using the first set of information items, identifying a matching transaction from the plurality of transactions that pertains to the record, and (iii) resolving the second set of information items using the matching transaction. The computer system can classify the record in a user account of and generate an expense report for the user.
