A GST invoice is a tax invoice that includes the GSTIN (Goods and Services Tax Identification Number) of the registered business of the user, as provided by the user, and the entity name of the registered business of the user, as provided by the user. Flipkart provides a GST invoice for all products purchased on the platform, except for products that are not eligible for a GST invoice, such as those that have Value Added Services of Complete Mobile Protection or Assured Buyback attached to them. Users with registered businesses may purchase products on Flipkart and avail GST benefits by entering their GST details during order placement. Flipkart sellers must register for GST if their annual turnover exceeds the prescribed threshold limit, and they must issue a GST invoice to the buyer, including their GSTIN, address, product details, quantity, tax, and other details.
