Founded in 2003 in New Delhi, DSD & Co. was established with a clear purpose — to provide businesses with not just compliance support, but genuine financial partnership. Over the past 22 years, our firm has grown into a comprehensive Chartered Accountancy practice, built on a foundation of integrity, technical excellence and a deep commitment to our clients' financial well-being.
What began as a focused tax and audit practice has evolved to encompass business advisory, litigation support, forensic accounting and — most recently — AI-powered financial process automation. We have consistently embraced change, adopted technology and expanded our expertise to stay ahead of an evolving regulatory and business landscape.
Today, DSD & Co. serves clients across Manufacturing, Retail, Services, Startups and Banking sectors — bringing the same dedication, attention and quality of service that has defined our practice since inception.
Each of our partners brings decades of specialised expertise and a deep commitment to client service across all areas of Chartered Accountancy practice.
