Offline Method of Bulk IRN Generation

The Government’s e-invoice system offers you an offline method to generate multiple Invoice reference numbers in one go.

This blog will summarise this process across the e-invoicing portal.

1. Navigate to the home page of the e-invoice portal and have a 2010 or higher version of MS office handy. Next, browse through “Help,” “Tools,” and reach “Bulk Generation Tools.” Then, download the most appropriate “JSON preparation tool” format from the below formats categorised based on classes of taxpayers and transactions :
   • Format A– has a single worksheet in which you can enter invoice and item details to prepare a JSON file.

   You can then upload many e-Invoices by a single upload to the Invoice Registration Portal (IRP).

   You can use this format if your business has 1 or 2 items in the invoice and deals with B2B transactions.

   You can enter the seller GSTIN details in the Profile as a one-time entry and cannot enter “Payment details and Reference details”. Refrain from repeating the same invoice details for all the invoice items.

   • Format B– consists of two worksheets in which you can enter invoice and item details separately.

   You can use this format if your business has many items in the invoice. Ensure you reference every item with the document number, type, and invoice date.

   You cannot enter Payment details and Reference details on the invoice worksheet.

   • Format C -consists of five worksheets in which you can enter invoice details, item details, payment details, reference details and additional details separately.

   You can use this format if your business has many items in the invoice with payment details, reference details, etc.

   As you enter the item details in different worksheets, you must reference every item with the document number, type, and date of the invoice.

   1. Format D– consists of a single worksheet in which you can enter invoice details, item details, payment details, reference details and additional details in the same worksheets.

   You can use this format if your business has many items in the invoice with payment details, reference details, etc.

2. Enter all the seller GSTIN details in the ‘Profile’ sheet.
3. Enter all the details of the invoices in the necessary fields as given in the ‘Invoice’ sheet. Then, ensure you follow the e-invoice schema and validate the components using the ‘Validate’ button.
4. Upon successful validation, click on the “Prepare JSON” button. The JSON file will now contain details of the multiple invoices entered.
5. Login to the e-Invoice system and upload the file(size- not more than 2MB) containing the multiple requests for IRN.
6. You can see the results of your requests in a table and a summary of the JSON file’s contents.
7. You can then download the table details into your system for further use and action.
