The New York payment software provider ACI Worldwide Inc. said it has agreed to outsource some of its technology services to International Business Machines Corp.

IBM, of Armonk, N.Y., will supply ACI with mainframe management and other related services. ACI said the seven-year deal will save it $25 million to $30 million.

"By outsourcing infrastructure management to IBM, we can leverage their worldwide resources to consolidate our data centers, upgrade hardware and software, and standardize on proven tools and processes to improve our operational performance," David Morem, ACI's senior vice president of global business operations, said in a press release last week.
