Description Oklahoma's state motto is "Labor Conquers all Things," so it's fitting that DCA Services calls this state home. DCA Services works to provide back office services to telecommunications providers such as wireless and long-distance resellers, facilities-based carriers, Internet Service Providers (ISPs), and competitive local exchange carriers (CLECs). It handles inbound customer service, billing management, and accounts receivable; bill printing and mail management; and electronic bill presentment and payment (EBPP) services. The company also has a suite of application service provider software that allows clients to access and monitor their accounts online. DCA Services is a subsidiary of investment firm Platinum Equity.
