Since its founding in January 2004 by Onchinsuren Dendevsambuu in Ulaanbaatar, Onch Audit has been prominent in its delivery of consistent high quality advice and service to clients in Mongolia.

Initially only providing auditing services, we have now expanded our services to tax and consulting services including accounting services outsourcing, risk assurance, financial systems design and implementation, and advising clients on business process improvements.

Onch Audit formally joined forces with the Deloitte Brand on 1 January 2012, to form Deloitte Onch LLC.
