Information technology act, of 2000

Dearest reader, 
I totally understand your concern and excitement about this big step for your company. I would like to give you some advice as per your query, that might help you out. 
First of all, you have to get an Import-Export Code (IEC) issued from the office of the Directorate General of Foreign Trade (DGFT), as per the guidelines of the Ministry of Commerce and Industry in India. This code is essential for companies that are looking for international trade as per the provisions and amendments of The Foreign Trade (Development and Regulation) Act, 1992. 
If you also looking forward to having a physical office in other countries, then you will have to register your company fulfilling the regulations of the country in which you will be establishing your company. This procedure and its conditions may vary from country to country as each country has its specific business licenses and permits for foreign entities. 
You will also have to check the provisions of the Double Taxation Avoidance Agreement (DTAA) that India has with several other countries to avoid being taxed twice. This can be seen in the case of Azadi Bachao Andolan v. Union of India (2003), as the Supreme Court upheld the DTAA, for the protection of Indian business from double taxation.   
You will have to make sure that your company complies with the Foreign Exchange Management Act (FEMA), 1999 as this regulates all the payments that are made cross-border. 
You might require the permission of the Reserve Bank of India for certain transactions. Registering under the RBI is often needed while promoting the company's overseas subsidiaries and joint ventures under FEMA.

Finally, if your company has proprietary technologies or brand identity, seek their protection in the form of international patents, trademarks, and copyrights by filing with the World Intellectual Property Organization (WIPO).
Rest, I would like to wish you very all the best for this big step of your company.
