Hello Gauri,
The scope for ACCA in India is growing at a tremendous pace. ACCA members are securing professional jobs all across the countries in companies such as EY, PwC, Deloitte, KPMG, Grant Thornton, BDO, Accenture, McKinsey, Tata, Barclay's, Standard Chartered, etc.
Profiles for ACCA members in India include Accounting Advisory, Risk Advisory, Corporate Finance, Audit and Assurance, Internal Audit, Taxation, Investment Advisory, etc
DIFFERENCE:
the courses mentioned have very less overlap ; further while CS deals with Indian laws and procedures, ACCA being an international course won't gel with it.
