Abacus Data Systems Inc. announced on May 17 that it acquired Toronto-based Amicus Attorney, a practice management solution for lawyers. Financial terms of the transaction were not disclosed.

Abacus, located in San Diego’s University Towne Center neighborhood, provides case management, time billing and accounting software for law firms. Providence Equity of Rhode Island recently took a majority stake in Abacus.

Alessandra Lezama, CEO of Abacus, called the acquisition “the logical next step for Abacus. In joining forces with Amicus, our customers, employees and stockholders will benefit from being part of a more diversified industry leader with significantly greater market opportunities,” Lezama said in a prepared statement.

“Our combination creates a more influential industry player with a commitment to product innovation and integration, which is key to the success of legal professionals in today’s highly digitalized world that has redefined the practice of law.”

Lezama said there will be no changes to either companies’ management or staff.

Abacus said there may be more acquisitions ahead.
