DNS Accountants started in 2005 as a traditional accountancy practice by Sumit Agarwal. The practice saw rapid organic growth culminating in the development of its own, award nominated, online accounting software and expansion by acquisition.

We were nominated for 4 awards at The British Accountancy Awards 2013; Independent Firm of the Year South East England; Accounting Technician of the Year (Sumit Agarwal – Founder & Managing Partner); Online Accountant of the Year and Client Software Product of the Year. We subsequently won Online Accountant of the Year cementing our place as one of the country’s leading online accountants.
