Silicon Valley-based CPA firm Abbott, Stringham & Lynch (ASL) has acquired finance and accounting solutions provider ArightCo, expanding its outsourced accounting and advisory capabilities for growing businesses. The companies announced the acquisition on May 14, with the deal taking effect immediately. Financial details were not disclosed.
The acquisition brings together two firms that focus on supporting mid-sized businesses with accounting, finance, and strategic advisory services. ASL said the move will strengthen its client accounting services platform and expand support for companies seeking scalable finance operations.
ASL Expands Client Accounting Services
Founded in 1977, ASL is a full-service CPA and advisory firm headquartered in Campbell, California. The firm provides tax, assurance, valuation, litigation support, succession planning, and accounting services to privately held businesses and high-net-worth individuals.
ArightCo, founded in 2008 and based in San Jose, California, specializes in outsourced finance and accounting solutions. The company supports businesses in industries including technology, SaaS, manufacturing, IT services, and nonprofit organizations.
According to the official announcement, ArightCo provides services ranging from bookkeeping and accounting support to controller and CFO-level financial management.
Deepa Bhat, Managing Principal at ASL, said the acquisition will help the firm expand the range of services available to clients.
“We are thrilled to welcome the ArightCo team to ASL and to further enhance our client accounting services with outsourced finance and accounting solutions,” Bhat said in the company statement.
She added that the partnership would expand the breadth and depth of services provided to mutual clients.
Focus on Growing Mid-Market Businesses
The acquisition reflects increasing demand from mid-sized companies for outsourced finance and accounting support. Many businesses are seeking flexible financial management solutions without building large internal accounting teams.
ArightCo operates as an extension of a client’s finance department, handling accounting operations, financial reporting, and strategic financial support. The company’s service model is designed to help businesses manage growth while maintaining operational efficiency.
Sushama Chowdhury, Co-Founder of ArightCo, said the partnership with ASL would provide clients with broader resources and expertise. She said the combined organization will be better positioned to support clients as their financial and operational needs continue to evolve.
Strengthening Presence in Technology and SaaS Sectors
ASL said the acquisition will further strengthen its presence in the technology and SaaS sectors, where ArightCo has built a strong client base. The firm also plans to continue serving its established industries, including real estate, construction, renewable energy, and manufacturing.
The deal comes as accounting firms increasingly expand beyond traditional tax and audit work to provide year-round advisory and outsourced finance services.
ASL has continued to grow its operations in recent years. In 2025, the firm announced the expansion of its global delivery capabilities with a new talent hub in Hyderabad, India, aimed at supporting long-term client service growth. With the addition of ArightCo, ASL is expected to further strengthen its outsourced accounting platform and broaden its advisory offerings for emerging and middle-market companies.
