The upgraded system will have features such as parallel processing of clearances, virtual meetings with departments, artificial intelligence-based chatbot facility, and deemed approval for select clearances. It is likely to provide more than 200 government to business (G2B) services by March next year. The biggest challenge before the State to improve its ease-of-doing-business ranking was that the single window portal and services by departments were yet to be provided online. These include registration under legal metrology, weights and measures and change of land use.
