Franchising is a contractual relationship between a franchisor and franchisee where the franchisor offers business support to the franchisee in exchange for fees and royalties. The franchisee operates under the franchisor's brand name and system. There are advantages to both parties - franchisors gain faster growth and revenue, while franchisees benefit from an established brand, support system, and proven business model. However, franchising also comes with disadvantages like loss of independence and contractual restrictions for franchisees, and reduced control and support costs for franchisors.
