New Delhi [India], January 22: The Federation of Indian Micro and Small & Medium Enterprises (FISME), a not-for-profit working towards the progression of Indian MSMEs, is seeking additional 9 months of time till 25th September 2025, for the successful implementation of the Invoice Management System (IMS). This comes on the backdrop of the advisory issued by The GST Network (GSTN) to introduce the IMS functionality on the GST portal in September last year. A proper pilot for a 9-month period allowing for testing, feedback and refinement before a full nationwide launch will ensure successful implementation.
