Customer calls for maintenance and repair for customer equipment are handled automatically in a computerized network. A central dispatch office receives customer trouble calls. A number of available technicians, in the same geographic location as the customer, can accept the assignment to clear the customer equipment problem. Each of the technicians has a hand-held wireless computing device that communicates wirelessly over the Internet with the main server computer at the central dispatch office. The main server computer automatically creates a service call for each customer problem and these service calls are communicated wirelessly over the Internet to the technician's hand-held device. Various screens on the hand-held device allow the technician enter job completion data, and order parts and equipment, and carry out customer contact maintenance functions. The main server computer invoices and bills the customer for the completed work.
