E-invoice under GST is the government's endeavor towards making the billing system more transparent and reducing tax frauds done based on false bills. E-invoices shall firstly be generated on the company’s billing software and then be validated through GSTN (generally B2B invoices). Directly generating E-invoice under GST through the giant portal is not possible.

Generate and Validate a GTS E-invoice

• Creating the GST invoice using own software
• Generating a unique Invoice Reference Number (IRN) for the B2B invoice
• Convert the invoice into the JSON file and later upload it on Invoice Registration Portal (IRP) with the IRN mentioned
• IRP will thereon validate the file with the Central Registry of GST. IRP will digitally sign the file
• The verified JSON file will be uploaded on the E-way bill and GST system
• The validated JSON file can be downloaded by the seller and will also be sent to the buyer on his mail id
