Indian Visa online application once is submitted and paid for can't be amended. The Indian e-tourist visa and Indian e-Business Visa are two completely different categories that serve entirely different purposes. The Indian tourist visa only permits you leisure and tourism-related activities such as visiting different places for fun and personal enjoyment. You can't do any commercial activity under this visa category. If you need an Indian Business Visa to perform business meetings or any such activity related to business then you are required to submit a fresh application.
