Top 100 Firm Clark Schaefer Hackett has acquired outsourced accounting firm Keelsra Business Services.

Keelsra, which was founded in 2005 and is named after founder Scott Campbell’s three daughters, specializes in serving nonprofits and small businesses.

“The demand in the marketplace for outsourced accounting services continues to grow,” said Kerry Roe, president of Clark Schaefer Hackett in a statement. “As a result, we continue to invest in expanding our outsourced accounting and advisory capabilities.”

The firm’s staff will join CSH’s Springfield, Ohio, office.

“This expansion adds to our capability to partner with clients needing full-service accounting services,” said Devesh Kamal, shareholder-in-charge of CSH’s Springfield office. “We are also happy to contribute to the overall growth in downtown Springfield with this acquisition.”

“My priority has always been to serve the best interests of my clients and the people who work here,” Campbell said in a statement. “This unification accomplishes both: My clients will have access to additional resources and more sophisticated services and my people will be able to realize the benefits of being part of a larger professional services firm. … Because of the work we do, taking accounting, payroll and other business tasks off their plate, our clients can focus on their own missions to improve the lives of others.”

Financial terms of the deal were not disclosed. Cincinatti-based CSH ranked No. 70 on Accounting Today’s 2019 list of the Top 100 Firms, with $64 million in revenues, 42 partners and over 400 employees.

Earlier in 2019, the firm expanded to Michigan with a double merger in July.
