Chrome extension for the GST Portal

Your GST returns, saved from your own session.

Pack downloads your filed GSTR-3B and GSTR-1 returns and your auto-drafted GSTR-2B statements from the GST Portal session you already signed into. Pick the return and the period; Pack finds the document on the portal page and saves it to your computer.
