About Us
Owners
Guru Amrit and OngKar Khalsa, owners of One Source Bookkeeping, started the company in 2008 with the mission to help small businesses transition from an “owner-does-everything” mentality to a mature business model that can grow. We are passionate about our mission because we have been there and know the challenges, having started and grown several businesses in Northern Virginia over the last 15 years.
In 2002, Guru Amrit and OngKar started Nationwide Processing, Inc., which has and continues to provide mortgage processing services to mortgage brokers across the US.
In 1999, Guru Amrit co-founded FirstRing, Inc, a relationship management company serving the credit card industry. FirstRing was bought by ICICI OneSource in 2003.
In 1992, Guru Amrit co-founded a medical transcription company, HealthScribe, Inc. HealthScribe was purchased by Soros Equity in 2004 and currently employs over 3,000 people.
