Armanino acquires Keystone Business Services

Armanino has acquired Keystone Business Services, an Oracle NetSuite provider.

Under the deal, the San Ramon, California-based Top 25 Firm plans to integrate Keystone’s NetSuite practice with its existing ERP and consulting capabilities. It will also add Keystone’s integration and management specialists.

Armanino took a minority investment from private equity firm Further Global Management in October 2024. Since then, Armanino added to its ERP tools and AI solutions by merging in Complete Business Solutions in February, expanded into Utah by merging in Cooper Savas in May, and added to its outsourcing capabilities by merging in Strategic Accounting Outsourced Solutions in July.

“Keystone is a fantastic cultural and operational fit that helps fill a critical gap in our ability to offer a diverse range of ERP solutions with the technical expertise Armanino is known for,” Armanino Advisory CEO Matt Armanino said in a statement. “Eric and his team bring tremendous NetSuite knowledge and a track record of long-term client success. Looking ahead, together we are well positioned to help more organizations modernize their systems, improve efficiency, and prepare for growth in a world that is in constant change.”

Keystone, based in Oak Brook, Illinois, offers customized cloud-based solutions in industries like manufacturing, distribution, food and beverage. 

“We’ve grown our firm through deep client relationships built on trust and strategic foresight, two pillars that mesh seamlessly with Armanino’s approach to digital transformation,” Eric Jozwiak, founder and president of Keystone Business Services, said in a statement.” Our clients will now benefit from an expanded suite of services that a national firm of scale provides — from AI strategy to tax, and everything in between. Through this integration, we will create a higher level of service for our clients and more opportunities for our people.”
