Onch & Company was founded in January 2004 as Onch Audit LLC for the sole purpose of providing trained, highly qualified, experienced, and independent local auditors. The founder and current Managing partner Onchinsuren Dendevsambuu had significant experience in auditing both global and local organizations in Mongolia and Russia at the time she founded Onch Audit. From initially only providing auditing services, the firm successfully expanded its services to include tax consulting, accounting outsourcing and advisory services to its clients.

​

Onch Audit joined the Deloitte network in 2012 and operated under Deloitte for 10 years until Deloitte’s global decision to withdraw from the Mongolian market due to the present macroeconomic business and market challenges. With effect from 1 February 2022, rebranded as Onch & Company, the same local management and team members have been successfully continuing to serve our clients and market with the same level of commitment and responsibility as we have been providing since its founding.
