Setting up a business in India is set to become simpler and easier in the coming years as the government has already set up several measures to reduce the time required to set up business in India.
To get things done electronically, the company must first apply to get a digital signature certificate (DSC) from MCA authorized agency or through their website here: http://mca.gov.in/MinistryV2/Rolecheck.html
Further, the director of the company would require director identification number (DIN) which can be obtained here: http://mca.gov.in/MinistryV2/din.html
Once the DSC is acquired, the company can e-file INC-29 form and send various supporting documents to Ministry of Corporate Affairs (MCA) to get approval for the business.
The time required for the entire process is approximately 2 to 3 weeks and the total cost of setting up business in India is approximately Rs 25000 to Rs 30000 (around USD $500), depending on the type of company.
