Professional Billing for Indian Businesses (FY 2025-26)

In the GST regime, an invoice is more than just a request for payment; it is a critical document for claiming Input Tax Credit (ITC). Under Rule 46 of the CGST Rules, 2017, a tax invoice must contain specific details to be valid. Missing a GSTIN or an HSN code can lead to legal penalties and blocked credits for your clients.

Our GST Invoice Generator is built to take the complexity out of compliance, allowing you to generate professional, tax-ready bills in seconds.

The Anatomy of a Perfect GST Invoice

  1. GSTIN Mapping: A valid invoice must clearly state the GSTIN of both the supplier and the recipient (for B2B transactions).
  2. Tax Components: Our tool automatically calculates CGST + SGST for intra-state sales and IGST for inter-state sales based on your provided address.
  3. HSN/SAC Codes: Harmonized System of Nomenclature (HSN) codes are mandatory for goods, and Services Accounting Codes (SAC) for services. These determine the tax rate (5%, 12%, 18%, or 28%).
  4. Place of Supply: This critical field determines the nature of the tax. We help you identify this based on the recipient's state.
