B.Com

You have multiple options after B.Com such as MCA, M.Com, MBA and finance certifications.
You will be eligible to do MCA if you had maths at +2 stage. It is a very good option if you want to make your career in IT industry.
M.Com focuses on commerce, accounting, management and economics related subjects and prepares you for finance and accounting jobs in enterprises.
MBA is a generic course on business management and administration and it focuses on functional areas of business such as accounting, finance, marketing, human resources, and operations. MBA provides wider options in different functions and various types of industries. Although, you must do post graduate degree based on your interest area, I will recommend MBA with finance specialization for better career opportunities and growth. You can top up M.Com and MBA qualifications with various finance certifications such as CMA, CFA, LOMA, etc. for career growth.

The best options in front of you after a B.Com (honors) are:
1. MBA finance from a reputed B-School which has 100% campus recruitment. You need to appear for CAT or similar exams for that. It's of no use to waste 10 to 20 lakhs INR in an ordinary MBA college as they are abundant in the country nowadays. Most students passing out from ordinary MBA colleges are either remaining unemployed or working for 5 to 10k salaried jobs. So if it is an MBA, it must be from an IIM or similar ranked B-school.
2. You may go for Indian Professional Accounting Course like CA/ICWA. However, get ready to study hard for the next 3 to 5 years before you start your career as you have to pass 14 / 15 papers (Pass rate of CA/ICWA exam is 8% to 9% in India.)
3. You may go for an International Professional Accounting course like CMA US. It has 2 papers, smart compact syllabus which you can pass within 6 months to max. 1 year and has International Value. Being a CMA US you can start with your career joining a good MNC like Deloitte/ PWC / TESCO/ Capegemini/ Caterpillar by 2017 with a minimum salary of 40 to 50k.
