The modification type depends on your business size and turnover:

1. Basic Registration Modification For small businesses (turnover up to ₹12 lakh). This is a simple update for petty retailers or home kitchens changing basic details like a shop name or contact info.

2. State License Modification For medium businesses (turnover ₹12 lakh – ₹20 crore). Required for restaurants or local units shifting locations or adding new food items to their production.

3. Central License Modification For large businesses (turnover above ₹20 crore or import/export). Necessary for major corporate changes, moving a head office, or expanding operations across states.
