Hello Kajal

Company Secretary (CS) is one of the principal officers of the company. They keep the company's records; complete the company's tax returns; advise the Board of Directors of their legal obligations to ensure that companies comply with statutory legislation.

CWA also performs the activities what CA performs like auditing a company but they audit about cost. They are known as Cost Auditors. The main objective of cost accountants is helping business to earn more profits.

According to me CS is better than CWA because of its vast area of working. CWA is quite limited to cost accounting where as CS is much more than that.

Best of luck
