Dear Firojuddin ji, The Bombay S&E Act 1948, under which you obtained the Gumasta Licence, is now repealed by the Maharashtra Government with the introduction of the new Act, viz., The Maharashtra S&E (Regulation of Employment and Conditions of Service) Act 2017.
Under the provisions of the new Act, you are not required to obtain a license under this Act since you have fewer than 10 employees. However, you are required to merely give an intimation of having commenced/doing the business to the Facilitator, i.e., S&E Inspector, by submitting the online application in the prescribed form.
