SWK paid $700,000 for Hightower and received that much from the annual maintenance income that produced gross margins in excess of 85 percent. "Our payback on that particular investment was measured in months, instead of years," Meller said. SWK is the only revenue-producing business of SilverSun. Meller also said SWK and SilverSun plan to aggressively pursue acquisitions of cloud companies, included those provide infrastructure, software, platform and database as a service offerings along with seeking application hosting companies. He noted that the company's managed services practice is strong and that is the area in which "we anticipate the most acquisitions."  SWK will also continue to roll out Sage resellers in North America. "We anticipate doing it again and again," he says. While those businesses have low growth, SWK can leverage its more than 99-percent client retention rate and sale additional products to the customers of the resellers it buys.
