A program tracks all aspects of reoccurring maintenance contracts and automatically creates the monthly invoice for the customer. The program tracks Customer Information, the contract type, the work location, what equipment to service, what work to perform, the beginning and end of the contract period, the days to perform work, how often the service is performed, the personnel and/or a vehicle required to perform the work, and the materials and labor expended.
