D+H chief executive Gerrard Schmid said the deal gives the company the scope and scale needed to compete in the U.S. market.
"It more than triples our U.S. customer base and expands our business into profitable and growing new areas of the U.S. fin-tech market," Schmid told a conference call with financial analysts.
"It rebalances our revenue geographically and by service line, providing a good boost to our strategic diversification efforts."
D+H said the deal for the financial services software company will give it access to 5,400 U.S. bank and credit union clients.
"It delivers a solid financial return by materially increasing our revenues and earnings with good margins, is accretive and makes us more comparable to our U.S. publicly traded fin-tech peers," Schmid said.
