A location visit confirmation service includes a portable wireless device, a schedule of predetermined sites, a location identification means and a central processor. The central processor periodically receives position data generated by the location identification means identifying the location of the portable wireless device. The central processor compares this position data to the schedule of predetermined sites. Using a threshold based on distance, or distance and time, it is determined whether a service person completed a visit to one of the sites in the schedule. At the end of the site visit confirmation evaluation period, a summary report is generated that confirms those scheduled site visits that were completed. The summary report is provided by the wireless carrier to the subscriber.
