In 1980, Jerry Klopfenstein became the Oklahoma dealer for A-Systems Accounting Software called Contractor III. This was the original DOS based program provide by A-Systems. In 1999, Jerry was instrumental in helping A-Systems transition from a DOS based system to a Windows based system. During this transition, the current overview screens that we now enjoy were added to the program as well as many upgrades and additions. A-Systems has continued to update and improve the program each year by incorporating customer requests.
