Steps in e-Invoice generation

The seller generates Invoice in ERP/Accounting software

  • This data needs to be converted to a JSON format and uploaded to the IRP portal
  • The IRP receives this information and crosscheck whether the invoice is already registered or not.
  • A unique number called IRN (Invoice Reference Number) will be generated if not registered already.
  • Rejects the data if already registered
  • IRP return a digitally signed JSON and QR code containing the IRN back to the seller
  • The registered Invoice data will be shared with GST eco system (GSTN and E-Way Bill portals)
  • In the GSTN portal and E-Way Bill portal , a de-duplication check will happen to ensure that the same information is not stored earlier
  • This data will get auto-populated in the ANX-1 of the supplier as well as in the ANX-2 of the buyer

Digitally signed QR Code

The QR code will contain the unique IRN (hash) along with some important parameters of invoice and digital signature so that it can be verified on the central portal as well as by an Offline App. This will be helpful for tax officers checking the invoice on the roadside where Internet may not be available all the time. Authenticity of the QR code can be validated using the digital signature.

  • JSON Web Token (JWT) and JSON Web Signature (JWS) are used to sign the invoice.
  • JWS is a compact signature format for representing signed content using JSON data structures. It contains Header, Payload and Signature.
  • Signing Algorithm SHA256RSA.
  • The public key to verify signature will be provided by GSTN

The QR code will consist of the following e-invoice parameters:

  1. GSTIN of supplier
  2. GSTIN of Recipient
  3. Invoice number as given by Supplier
  4. Date of generation of invoice
  5. Invoice value (taxable value and gross tax)
  6. Number of line items.
  7. HSN Code of main item (the line item having highest taxable value)
  8. Unique Invoice Reference Number (hash)
