Shop and establishment registration
Your state's registration for a shop, office or commercial premises, also called a trade or labour licence.
Each state has its own Shops and Establishments Act, and most shops and offices register under it soon after opening. It sets rules on working hours, holidays and staff records, and many banks ask for the certificate before opening a current account.
Because it is a state law, the form, fee and any exemption for small shops differ from state to state — check your own state labour department's portal.
