Reconciliation subsystem for use with a system for recording, analyzing, verifying, and reporting of product used, sold, or transferred from multiple locations at various prices or costs to different customers in a business or in commerce, and generating consolidated billing notices. The reconciliation starts by logging the session start time and retrieving the last session start time, and retrieving the logs from the feeder and the interim control points. If there is an error at this point, the appropriate notification is issued, the session status is logged, and the reconciliation process ended. If there is no error, the records are compared, checked for unreconciled records, and the report prepared and published. Session status is logged, and the reconciliation process is ended.
