What is an Invoice?
An invoice is a commercial document issued by a seller to a buyer, listing the products or services provided, quantities, prices, and payment terms. For businesses in India, a proper tax invoice is a legal requirement for GST compliance, and serves as proof of sale for both accounting and tax filing purposes.
Elements of a GST Invoice in India
A GST-compliant invoice must include: supplier's name, address, and GSTIN; invoice number and date; recipient's name, address, and GSTIN (if registered); HSN/SAC code; description, quantity, and value of goods/services; rate and amount of CGST, SGST, or IGST; place of supply; and total value. Our generator covers all mandatory fields.
