GSTR-1 CSV export – Download a GSTR-1-ready CSV file for any month. The file is formatted for direct upload to the GST portal.
GST rate flexibility – Supports 0%, 5%, 12%, 18%, and 28% GST rates. Set the rate per product.
GSTIN validation – Your store's GSTIN is validated at signup and printed on every bill and receipt.
