Dear Sir, If you want to start any business for profit which has legal sanctity, you can do either as a proprietor or under partnership firm or under a company limited by shares. You need to decide the mode first and it all depends upon your expected size of business, exact nature of business, whether all the finances can be internally arranged or the same is to be tied with up with any banker and are there any associates with or without financial interest in the proposed business and where do you want to start the business etc.,. Anyhow, the formalities and compliances for any of the above are very limited and there are any number of agencies like, Chartered Accountants and Company secretaries etc., in every city to guide you. However, post registration compliances and requirements are many and who so ever is starting the business should adhere to such post compliances.
