Franchising involves a franchisor licensing a franchisee to do business using the franchisor's brand and systems in exchange for monetary compensation. India is seen as an attractive market for fast food franchising due to its projected 18% annual growth in the fast food sector to $27.57 billion by 2020, with vegetarian fast food making up 45% of the market. Key considerations for opening a fast food franchise include conducting market research and developing a business plan, selecting an optimal location, deciding on product and service offerings, hiring qualified staff, and implementing effective marketing strategies.
