Nationwide electronic or e-way bill system for inter-state movement of goods has been rolled out on Sunday, with GSTN officials saying that the platform is working smoothly. Karnataka is the only state which has implemented the e-way bill system for moving goods within the state. The state has been using the eBay bill platform since September last year for intra-state movement of goods. Businesses and transporters have to produce an e-way bill before a GST (Goods and Services Tax) inspector for moving goods worth over Rs 50,000 from one state to another.
