Hi Kanaka
The audit has to be defined for each company separately as the business processes are different for each industry type.
But basically you will need to do audit on following departments within the branch, You need to prepare formats, check lists for each of this separately.
1. Accounts [proper documentation, bank and cash reconciliation, all payments properly authorized etc]
2. Employee records [proper maintainance of attendance register, leave records, applications etc]
3. Stock register [cross check with the actual stock]
4. Stock taking of official furniture / assets [checking with actual and checking the conditions as well]
5. Official Documents [latest Licence from Municipal corporation / shops and establishment department, insurance etc]
6. All other business related files [customer files, contract files, vendor files etc. should be checked and seen if the company standards / policies are followed in the contracts]
I have listed just few, you can add to it depending on the functions your branchs perform.
For every audit you will have to have a different format and check lists so that non of the items is missed when an auditor goes for auditing.
