Procedural Aspects of E-invoicing in GST

Important terms:

Invoice Reference Number (IRN): The IRN is a unique number generated by an e-invoice system using a hash generation algorithm. The unique IRN will be computed according to the Goods and Service Tax Identification Number (GSTIN), year, and document number. The generator of the document can also create an IRN of their choice within the given format.

QR Code: The QR Code captures the GSTIN of the supplier, GSTIN of Recipient, Invoice Number as given by Supplier, Date of Invoice generation, Invoice Value, Number of Line items, Harmonized System of Nomenclature (HSN) Codes, and Unique IRNs

The user can view the invoice anywhere from the portal or the app with or without internet access through the QR code.

1. Bulk Upload

IRN can be generated in bulk by using the Bulk Generation tools available in the Help section of the Home Page. This tool consists of four formats based on the type of Taxpayer. The taxpayer can select an appropriate type and use that tool to convert the Excel Files into a JavaScript Object Notation (JSON) file. The user is required to upload this JSON file to the ‘Bulk Upload’ option in the E-invoice menu. Once the file is successfully uploaded, the IRN is generated for each invoice and digitally verified with a QR Code. All the said invoices are viewed on the screen. Users can also download an excel file of the summary sheet. 

2. Cancel IRN

The user has to keep the E-invoice handy while cancelling the same. By clicking on this option, a screen will appear asking the user to enter either the Acknowledgement Number or the IRN Number as per the availability.

For Bulk Cancellation, the user will have to use the Tool Bulk to generate a JavaScript Object Notation (JSON) file. This JSON file has to be uploaded on the Portal, and the request will be considered to cancel the invoices mentioned therein. This process is similar to the Bulk Generation of IRNs.

E-invoice1 is a portal developed to streamline the invoicing system for the dealers and the Tax Authorities and keep track of the invoices through the IRN and QR Codes. However, amendments to the E-invoices have to be done only on the GST Common Portal by the taxpayer while filing the GST Returns. No amendments are accepted on the GST E-invoice portals. We hope, through this article, we have presented everything to know about E-invoice under GST.
