GSTN Verified E-Invoice App with QR Code

In its commitment to streamlining and ensuring precise e-invoice verification, the Goods and Services Tax Network (GSTN) has developed a highly efficient application called the GST E-Invoice QR Code Verifier. This app addresses the importance of seamless e-invoice authentication, aiming to simplify the process and enhance user convenience when verifying electronic invoices.

Understanding the Role of QR Code in E-Invoicing

In the e-invoice ecosystem, the QR code plays a pivotal role as it is specifically designed to be read and interpreted by machines. All e-invoices are now required to feature a digitally signed QR code. This inclusion of the QR code in e-invoices enables easy and convenient access to valid GST invoices.

The Significance of Including QR Codes in E-Invoices

The incorporation of QR codes is crucial in the e-invoicing system to ensure the integrity and validity of e-invoices. When taxpayers upload tax invoices to the e-invoice portal or Integrated Reporting and Payment System (IRP) for verification and authentication, the IRP conducts various checks on the invoice details. After a successful verification process, the IRP digitally signs the invoice, assigns it an Invoice Reference Number (IRN), and generates a signed QR code.

Ensuring Compliance and Avoiding Penalties

Compliance with the requirement of including the QR code on the final e-invoice is of utmost importance. Failure to do so can result in both the e-invoice and the subsequent e-way bill being rendered invalid and unusable. Non-compliance with this regulation may also attract severe penalties from tax authorities. Moreover, buyers may lose the ability to claim their entitled input tax credit if the QR code is missing or incorrect.
