How to Generate e-Invoices on GST e-Invoice Portal

Once you register for e-invoicing, the next question that comes to your mind is ‘How to generate an e-invoice’. The einvoice portal offers multiple methods to generate e-invoices – Using the free tool provided by the portal, through direct API integration, and API integration through GSP.

Step-by-Step Guide to Generate e-Invoices on GST e-Invoice Portal

Here are the different steps involved in creating e-invoices on the GST portal. 

Steps to generate e-invoice

Step 1: Create a JSON File of the Final Invoices

Even before generating an e-invoice, you need to have a regular GST invoice that is usually created to record a sale. You can either use a manual invoice or an invoice generated using billing software. However, you cannot report a normal invoice directly to the GST portal. Instead, you need to create a JSON file before uploading it to the portal for e-invoice generation. Now, the question is how to create a JSON file. Here is a detailed guide. 

  • Using GePP Tool to Generate JSON Files

If you generate invoices manually, either pen & paper-based or MS Word or Excel-based invoices, use the free offline tool provided by the e-invoice portal, ‘the GST e-Invoice Preparing and Printing (GePP) Tool’ to convert multiple invoices (up to 10) into a single JSON file.

The GePP Tool is a simple Excel-based tool designed to assist businesses not using any software or ERP solution to generate invoices. It enables businesses to create e-invoices and print them with QR codes. More suitable for businesses issuing 10 to 12 invoices per day. You need to have MS-Excel 2010 (or above) installed on your PC to use this tool. 

Here is a detailed guide to creating JSON files from manual invoices using the GePP Tool.

  1. Visit the e-invoice portal at https://einvoice1.gst.gov.in/
  2. Navigate to Help > Tools > Bulk Generation Tools

  5. Open the tool. On the left-side menu, you will find two options: ‘e-Invoice Menu’ and ‘Masters Menu’. The e-Invoice Menu has options to create and upload invoices, check pending invoices & payment details, import QR codes, print, generate, & search e-invoices. 
  6. The ‘Masters’ menu has ‘Supplier Profile’, ‘Recipient Master’ and ‘Product Master’. For first-time users, it is mandatory to enter the supplier, receipt, and product details, so the same will be auto-generated while creating invoices. 
  7. To enter supplier details, click on ‘Supplier Profile’ and enter Supplier GSTIN, Trade Name, Legal Name, Address, Phone Number, e-mail ID, etc. You can also add your company logo here so that the same will be printed on the e-invoice. 
  8. To enter receipt details, click on ‘Receipt Master’ and enter the receipt’s GSTIN, legal & trade names, address, and other details and click on ‘Update’. You can add multiple receipts in this tab. 
  9. To enter your product details, click on ‘Product Master’ and enter the details of your product, including description, unit, price, GST rate, state CESS, etc., and click on ‘Update. You can update the details of existing products whenever necessary using the ‘Product Master’.
  10. Once all these tabs are filled with the required information, you can now enter your invoice details to create JSON files. 
  11. Go to the main page, under the e-Invoice Menu, and click on ‘New Invoice’.
  12. e-Invoice Entry page with different fields to enter document details, ‘Bill To’ details, Transaction details, payment details, etc., will appear.
  13. Enter all the details using the data from your existing invoices. You can also enter the e-Way bill details, if applicable. Some fields like ‘Bill To’ and ‘Item Details’ will be auto-populated by entering the first three letters and by selecting the related option.
  14. Once all the details are entered correclty, click on ‘Submit’ to see the preview of the e-invoice. You may confirm the entry or edit, if required. 
  15. On confirmation, the e-invoice entry file gets created and the same will be available under the ‘Pending Invoices’ option. 
  16. You can enter a maximum of 10 invoices and keep them pending for IRN generation. 
  17. Once you’re ready for IRN generation, go to ‘Pending Invoices’ and click on ‘Validate’. 
  18. Once the tool validates the data, click on ‘Prepare JSON’
  19. The JSON file will be generated for all the pending invoices in the same file where your tool is located on your PC. If there are any errors in the entry, the same will be displayed in this step. Correct them and click on ‘Prepare JSON’ option again. 

Step 2: Upload JSON File to e-Invoice Portal

Once the JSON file is ready, you can upload it to the e-Invoice portal to generate e-invoices for all the invoices. Here is the detailed guide to generating e-invoices on the e-invoice portal. Please note that this step is applicable only for manual invoices converted to JSON using the GePP tool or other tool. For those using billing software, this step is not required as the software directly generates e-invoices.

  7. You will find the details of individual invoices with IRN and other details under the ‘Successfully Uploaded Invoice Details’ table in the portal. 

Step 3: How to Download & Print e-Invoice

Once the portal returns the invoices with unique identifiers or IRNs, you will have the option to either ‘Download the Signed JSON’ or ‘Download Excel’.

  1. Choose the ‘Download Excel’ option.

  5. You can print the e-invoices individually by clicking on the ‘Print’ option.

No, only the people who have been informed can report invoices to IRP now.

Is there a deadline by which I must report an invoice to IRP? Is there a validation that requires a "document date" to fall within a given time window to report to IRP and generate an IRN?

Is the supplier's signature (DSC) required when sending the electronic invoice to IRP?

What is an IRN, and how is it generated?

IRN (Invoice Reference Number) is a unique identifier for each e-invoice, generated by the e-invoice system using a hash generation algorithm. It's a 64-character code ensuring the uniqueness of each invoice.

How is the QR code associated with e-invoices generated?

Once an e-invoice is generated, the e-invoice system digitally signs it and generates a QR code. This code includes essential invoice details and the unique IRN, allowing quick validation and access from handheld devices.

What happens after generating an e-invoice on the portal?

The signed e-invoice data is sent to the GST system, updating supplier and buyer GSTR-1/2B/2A details and, where applicable, updating ‘Part A’ of the e-Way Bill, streamlining further compliance processes.
