GST e-Invoicing for businesses above Rs.10 crore turnover 

In India, there is a greater focus on encouraging a stronger culture of entrepreneurship and innovation.  

As a way towards that, the Indian government has taken a series of steps in the last few years, mainly in making business tax compliance less complicated by introducing comprehensive indirect tax system. 

Similarly, in the 35th GST council meeting, the council recommended to implement e-invoicing under GST that applies to specific categories of taxpayers.  

Recently, the government has notified that GST e-invoicing is mandatory for taxpayers with an annual turnover of more than INR 10 crores from 1st October 2022

In this article, we will learn about electronic invoicing, different phases of e-invoicing implementation based on the taxpayers' turnover limits and various modes to generate IRN.  

Do you think your business needs to generate multiple IRNs via an e-invoicing portal? 

Or even confused about whether it's applicable for you or not?

Now, let's get to it.  

Ever since the GST system came into being, the GST intelligence has unearthed numerous frauds involving fake invoices, bogus credits, etc. This flows from one fundamental flaw in the GST system - there is a time gap.  

In this context, the time gap is between when an invoice is generated and how & when the invoice is uploaded in the GST returns. This time gap is used for tax evasion.  

To avoid such tax evasion, the government-mandated e-invoicing under GST. A committee (CoO on generation of electronic Invoice through GST Portal) was set up on Apr 2019 to examine the applicability of e-invoicing and suggest its implementation plan in India. 

Since then, CBIC has released several notifications in a phased manner to bring effective integration between the business and the government's Invoice Registration Portal (IRP) that allows businesses to generate Invoice Reference Numbers (IRN) for every B2B invoice.  

Now that you know the purpose of the new e-invoicing system. Before we learn about the invoice turnover limit and phased implementation, let's understand what e-invoicing is.  

What is e-invoicing under GST?  

E-invoicing under GST means uploading an already generated invoice using your own ERP software like Tally, Quickbooks, SAP, Oracle, etc., to the Invoice Registration Portal (IRP).  

This portal will ensure the uploaded invoice is validated, verified, and authenticated by the government before it is shared with the customer/buyer.  

The government has created an exclusive portal solely to administer, generate, and monitor e-invoices.  


Kindly note that the E-invoicing does not mean generation of invoice by a Government Portal. 

In a nutshell, the process of electronic invoicing under GST goes like this: 

  • Step 1: Generate your invoice in the same way as before using your ERP software.  
  • Step 2: Upload the already generated invoice to the IRP portal (Not GST Portal).  
  • Step 3: The portal will perform certain mandatory verification and validation procedure based on a defined set of parameters.  
  • Step 4: Once your invoice gets validated and authorized, the portal will allot a unique reference number to your invoice, i.e., Invoice Reference Number (IRN).  

This becomes an e-invoice.  

The IRN Number is generated along with QR Code & E-way Bill. This QR Code must be provided in the invoice provided to the buyer/customer.
