The dictionary defines an estimate as “a rough or approximate calculation only.” The insurance company may provide an estimate; however, it is up to the repair facility to discuss the repairs and provide the estimate to the owner for approval and authorization. Often it is initially impossible to estimate collision damage without dismantling the vehicle. The repair order is an actual blueprint of the repairs done to the vehicle listing the parts, their origin, the labor operations, and other relevant items. It can only be finalized upon the completion of repairs.
