Abstar Disbursing Co.

Karpel Custom, a subsidiary of Karpel Computer Systems of south St. Louis County, has won a $400,000 contract to develop an application for Abstar Disbursing Co. of Clayton, a company that provides construction disbursing services and mechanics’ line coverage.

The Internet-based application will replace Abstar's in-house disbursing application. Abstar wants to offer the new system to other disbursing companies on a subscription basis, said John McEvoy, president of Abstar.

Karpel, based at 5714 South Lindbergh Boulevard, has created dozens of custom software and Web development projects, said its president, Jeff Karpel.
