Abstract: A method, system and program product for identifying redundant invoices. The method includes providing an accounts payable system having an invoice table that contains invoice data inputted from vendor invoices, executing an algorithm with the accounts payable system for identifying one or more redundant invoices among a current group of invoices chosen from the invoices inputted into the accounts payable system, where the algorithm identifies the redundant invoices among the current group of invoices using each of six redundancy criteria analyzed by the algorithm and outputting a perceptible report containing a separate section corresponding to each of the six redundancy criteria analyzed by the algorithm for identifying redundant invoices among the current group of invoices inputted into the accounts payable system, where a redundant invoice that is reported in one section of the perceptible report is not reported in another section of the perceptible report.
