A method includes retrieving a first data set from a billing system configured to facilitate a billing operation associated with a network. The first data set includes a plurality of billing records, which includes a first billing record associated with and including a field identifying a first circuit from a plurality of circuits included within the network. A second data set is retrieved from a configuration management system configured to facilitate an operation associated with the network. The second data set includes a plurality of configuration records, which includes a first configuration record associated with and including a field identifying the first circuit. When the field identifying the first circuit included in the first configuration record differs from the field identifying the first circuit included in the first billing record, a correct identifier associated with the first circuit is determined. When such a discrepancy exists, a report is produced.
