After completion of B.COM you can select from a wide pool of options available.

As you are interested in finance, my suggestion would be to pursue a professional certification such as Chartered Accountnacy, Cost Accounting, Company Secretary,etc. These courses are academically challenging yet they hold a high reputaion in the corporate world.

Another option is to look into colleges that offer MBA in finance. This would complement your undergraduate studies and improve your professional portfolio significantly.

Chartered Accountant/M.com/ Master of Business Administration/Certified Management Accountant/Certified Public Accounting/Association of Chartered Certificate Accountants/Business Accounting and Taxation are the various options available.
