What is the e-invoice bulk generation facility?

The bulk generation facility is provided by the Invoice Registration Portal (IRP) where multiple invoices can be uploaded at once. It is an offline excel-based tool to generate e-invoices by exporting invoice data from the billing system/accounting software or ERP of the taxpayer. The IRP would then accept a bulk request for uploading the JSON file of these invoices. After authentication, the IRP will generate a unique Invoice reference number (IRN) and Quick Response (QR) code for each e-invoice and digitally sign the e-invoice.

The taxpayer needs to have the EINV bulk convertor installed in his system. This is an excel-based offline utility which helps convert multiple invoices entered in the excel sheet into a single JSON file for bulk upload. In order to download this tool, visit the trial e-invoice portal. Go to Help > Tools > Bulk Generation Tools. Select the tool which is most appropriate.

Step 3: Once the invoice details are entered, to ensure that e-invoice schema is followed, validate the details using the ‘Validate’ button.

Step 4: Upon successful validation, click on the ‘Prepare JSON’ button. The JSON file will be generated, which will contain details of the multiple invoices entered.

Step 5: Log in to the e-invoice portal. Go to e-invoice > Bulk upload. Click on ‘Choose file’.
