Disclosed is a document processing system that can be used to automatically detect and process an invoice for a business entity. The system receives a document and determines the structural information from the document. The structural information includes a template object and its location on the document. The system further retrieves structural information of documents stored in the database and compares the structural information of retrieved documents to the received document based on matching criteria such as a template object name and its location. If a match is found within a predefined threshold range, the data is extracted from the received document and the structural information is extracted from the matching document and the received document is processed by applying the extracted data to the corresponding extracted structural information. The processed document is transmitted for a user review or for processing by an accounting or bookkeeping software application.
