Create a proforma invoice PDF — an advance bill before the sale — with items and GST.
Everything stays in your browser. Amounts are printed as “Rs.” because standard PDF fonts can’t show the ₹ sign.
A preliminary bill sent before goods or services are delivered; it is not a tax invoice.
Yes, make a tax invoice once the sale is confirmed.
No. Everything is worked out in your browser and nothing you type is sent to a server.
