For 35 years, Duncan Builders has been serving the needs of the community and the surrounding area. The company, owned b;y M.J. Lewis and Robert Davenport, includes four stores in Oklahoma. Each store is run independently with its own manager and staff. Duncan Builders began using Advantage in 1992. They found the Advantage system at a trade show and were impressed because Advantage could be customized. They purchased Advantage to streamline the stores' operations and use all of the pro- gram modules to maximize the efficiency of the software. All four locations use the Advantage system. The company M.J. Lewis and Robert Davenport have built is based on customer need. Even though the stores are run as individual businesses, they all operate on the same same principles.
