ELECTRONIC TRANSACTION PROCESSING SERVER WITH AUTOMATED TRANSACTION EVALUATION

An invoice processing system includes a document system and an invoice hub. The document system receives a document image (either a paper invoice or an image file). A character recognition system generates a data file representation of the invoice data from the document image. A data field value validation engine determines, for each data field, a rule associated with each data field. The rule is applied to the data field value to distinguish between a valid field value and suspect data value. A correction center: i) displays a portion of the document image comprising the suspect field value; ii) receives user input of a replacement value to replace the suspect field value as the data field value. The invoice hub receives the data file which includes all validated data field values and stores the invoice data in a transaction database. A spend management evaluation module performs an evaluation function of a selected one of a plurality of evaluation parameter sets to generate a resulting value. Based on the resulting value, the spend management module may determine an evaluation field value in accordance with the defined action associated with the resulting value. The evaluation field value is then associated with the at least one record of invoice data.
