GST E-invoicing Applications, Advantages and Procedure

E invoicing: Applications, Advantages, Procedures & FAQs

The new system of e-invoicing ensures standardization of invoices, bringing a systematic methodology to how B2B business is conducted

E-Invoicing is the introduction of a digital invoice at the government GST portal, for goods and services provided by business firms. The GST council in India set up a committee in May 2019 to discuss e-invoicing considering global implementations. Since then, several drafts of e-invoicing were issued and this was finally released in January 2020. The mandate went live from October 1, 2020 in a phased manner.


Why E-Invoicing?

Tax fraud using fake invoices has been a bane that the government was fighting even before implementing GST. What E-Invoicing does in the Indian context is that it mandates authorization of each invoice from the government portal called IRP (invoice reference portal). Such real-time invoicing discourages fraudulent transactions. Other than plugging the holes in tax leakage, other benefits of e-invoicing under GST that benefits taxpayers include:

  • Real-time tracking of invoices
  • One-time reporting of all GST filings
  • Minimized invoice mismatches
  • Easy input tax claims
  • Better management and automation of the tax filing process


What is the link between an e-invoice and e-way bills?

An e-way bill is generated when there is movement of goods in a vehicle whose value exceeds Rs. 50,000. A GST registered individual or business cannot transport goods that have value of more than Rs. 50,000 without an e-way bill. On generation of an e-way bill, a unique E-way Bill Number (EBN) is allocated that is available to the supplier, recipient, and the transporter.


E-way bills are directly integrated with the e-invoicing system. It is totally the taxpayer’s choice if they want to generate the E-way bill at the time of e-invoice generation or later by using the IRN as a reference. However, it should be noted that an e-waybill will be invalid without a valid e-invoice.


The government of India has also linked e-way bills to the GST return filing. E-way bill generation will be blocked for taxpayers who have two or more consecutive GST returns pending to be filed. This benefits businesses in the following ways:

  • Easy compliance for the taxpayers
  • Ensuring accuracy by automating the process
  • Benefits the government by ensuring reduced tax evasion

How Does E-Invoicing Work?

As per the regulations, e-invoices have to be issued to the IRP. The IRP then carries out the validation of the e-invoice to provide the supplier with a response message. If the IRP response is positive, the invoice gets a digital signature, and the IRP assigns it a unique number. A QR code is also generated for both the buyer and the seller to confirm its authenticity and to prove that it has been registered in the GST system, finally making the document available to both parties in the portal. However, if the response is negative, a message detailing the reason for rejection is sent.


The below fields get validated by the IRP system

  • Document details: type, number, and date.
  •  Item-related details like service/ goods, total amount, GST rate, HSN code, total item value.
  • Supplier details like legal name, GSTN address including location, PIN code, and state code.
  • Buyer details like legal name, GSTN number including, address, location, PIN code, and state code.
  • Transaction details like tax scheme and supplier type
  • Dispatch from address details
  • Billing and Shipping details
  • Invoice details include tax exclusive value, tax value and the total invoice value


How does e-invoicing impact businesses?

Businesses will have to make provisions for real-time upload of invoice data and printing of QR code. For this to happen, they will need to have the right technology that assists these provisions without having to change the invoicing process. Businesses using software that integrates with the IRP portal will find it smoother to manage the e-invoicing requirements. Furthermore, the entire behavior of businesses will change since the buyer will drive the supplier to upload invoices to the government-monitored IRP portal, as this will confirm his eligible input tax credit. This means that buyers will be more inclined to do business with those sellers who understand the necessity of quick and correct uploading of invoices.


How does Amazon Business ensure compliance for customers?

To support sellers comply with the Indian government’s e-invoicing system, Amazon Business has enabled a feature in Seller Central through which sellers can opt for generating e-invoices by storing fully encrypted IRP credentials in their account and authorize Amazon Business to generate GST e-Invoices on their behalf.

Amazon Business has also created a system where e-commerce operators can generate e-Invoices on behalf of the sellers for the marketplace transactions. For both marketplace and non-marketplace transactions, Amazon Business has enabled the generation of e-Invoices for sellers through the third-party GST Suvidha Provider (GSP).

Amazon Business has been educating sellers to perform the below checklist to ensure that the correct details are saved. This ensures the creation of accurate and compliant invoices from their Seller Central account. Sellers have to:


  • Verify their business address in Seller Central to ensure that the name of the State complies with ISO standards. For instance, if the state of business address is Maharashtra, then the state name in the business address should be Maharashtra (case-sensitive). Abbreviations such as MH or MA should not be used.
  •  Ensure that the PIN code is correct and corresponds to the GSTIN state in the business address under Account Info in Seller Central. More details on this can be found here.
