1) Factoring involves a business selling its accounts receivable to a third party called a factor at a discount. It provides businesses with immediate cash flow. 2) Factoring has grown in India at a CAGR of 10.4% from 2009-2014 but still only accounts for 2% of India's GDP, indicating significant potential for further growth. 3) The key challenges to factoring in India are the absence of a strong regulatory framework, high stamp duties, and lack of supportive legal structures. However, regulations are improving with the enforcement of rules like the Factor Bill of 2011.
