New Delhi [India], April 2: The India SME Forum (ISF), the country's largest non-governmental organization for small and medium enterprises, has urged the government to reconsider the timeline for the implementation of the Invoice Management System (IMS) under the Goods and Services Tax (GST) framework. Given significant operational and financial challenges faced by Micro, Small, and Medium Enterprises (MSMEs) in integrating IMS, the Forum is calling for a phased implementation for transition to ensure small businesses can adapt without financial or operational distress.
