ADP has acquired Celergo, a provider of payroll management services in 150 countries.

The acquisition is expected to improve ADP’s array of international payroll services with new cross-currency and expatriate payment services. ADP estimates the multi-country payroll outsourcing market to be over $3 billion today. The Roseland, N.J.-based payroll giant hopes to capitalize on the growing international market by acquiring Celergo as well as expand its human capital management offerings. The company also recently acquired Global Cash Card and WorkMarket.

Celego is based in Chicago and combines cloud-based technology with a local provider network. “Celergo enhances ADP’s multi-country payroll capabilities in a rapidly evolving global market and will improve the client experience and drive revenue growth,” said ADP president and CEO Carlos Rodriguez in a statement. “This builds on our recent acquisitions of Global Cash Card and WorkMarket, all of which address a changing workforce that is increasingly global, freelance or part-time, and requires flexible payment solutions.”

Celergo will extend ADP’s footprint, adding more than 200 multinational clients along with a team that has experience in providing multi-country payroll, a key priority area for ADP. Financial terms of the deal were not disclosed.

“We have long-admired ADP’s incredible scale and success and are thrilled to be joining the company at this exciting time in the global human capital management market,” stated Celergo Tim Callahan. “Our team has built strong solutions for our clients across the globe and I look forward to seeing how we can further excel in this shifting market with the support and resources of ADP.”
