Do we need to appoint cost auditor

Dear All.

We are an EOU and under the purview of Cost Accounting Records Rules 2011. However chapter code of our company was brought under the purview of Cost Audit through CAR order on 24th January 2012.

CARR 2011 specifically mentioned that Company should obtain compliance certificate either by employee cost accountant or from Practicing Cost accountant.

To get this compliance certificate from Cost Accountant do we need to appoint cost auditor though Board resolution and do we need to comply with the ROC formality of form filing 23C?

I have tried to search this but could not find the relevant information. Please help me to resolve my query.

Regards,
