The Micro, Small and Medium Enterprises Development Act, 2006 (MSMED Act) provides definitions for micro, small and medium enterprises based on investment in plant and machinery or equipment. It requires medium enterprises engaged in manufacturing to register with authorities and makes registration optional for others. The Act provides for timely payment to registered micro or small enterprises within 45 days and imposes 18% interest on delayed payments. It also establishes councils for resolving payment disputes. The Act requires disclosures in buyer's financial statements about amounts unpaid to micro and small suppliers.
