Respected Experts,
Can anyone please tell me whether any book is available in the market which practically explains about how to conduct an internal audit for a company?
2)Also what are the supporting documents that has to be verified for all the type of expenses, revenues, assets and liabilities?
3)How to link each departments work to other departments so that whatever appears in the accounts book is genuine.
Thanks & Regards,
Rajesh.
