If the registered person is making supplies to the other registered person then he has to file the return by uploading the details of supplies in invoice wise. However, if he is making supplies to an unregistered person then in case of interstate supplies if the invoice amount exceeds Rs. 2,50,000/- then he is required to file invoice wise details otherwise he shall file state-wise consolidated details and in case of intrastate supplies, he may upload the consolidated details of invoices.
