E-invoicing under GST has revolutionised the way businesses manage their invoices and compliance. Electronic invoicing or e-invoicing, in GST, refers to the process of reporting information on specific GST documents stated by GST law.
After reporting to a government-notified portal, a reference number is obtained. This process has been introduced to enhance transparency, reduce tax evasion, and streamline reporting related to the GST process.
Several aspects of e-invoices under GST law, such as how they work, how they can be modified, and more, are covered in this article, which will provide detailed information about e-invoice management under GST.
Key Components of an E-Invoice

E-invoicing is a system that authenticates B2B invoices and other documents electronically using GSTN. This is useful for other purposes in the future on the GST portal. There are a total of 30 compulsory fields in e-invoicing, which are as follows:
- Legal Name of Supplier
- Document Type Code
- Address of Supplier
- Supplier GSTIN
- State Code of Supplier
- Supplier Place
- Document Number
- Supplier Pincode
- Document Date
- Preceding Invoice Reference and Date
- Recipient’s GSTIN
- Recipient Legal Name
- Recipient’s State Code
- Recipient’s Address
- Pincode
- Place of Supply State Code
- IRN or Invoice Reference Number
- Recipient Place
- State Code, Pincode, and Shipping To State
- Shipping To GSTIN
- Is Service
- Place, Dispatch From Name, Pincode, and Address
- Item Description
- Supply Type Code
- Item Price
- HSN Code
- GST Rate
- Assessable Value
- Total Invoice Value
- SGST Value, CGST Value, and IGST Value Separately
How Does E-Invoicing Work?
Working with e-invoicing ensures effective e-invoice management through the following points:
● Businesses generate invoices and format them according to the official e-invoice schema under e-invoice management.
● Each invoice must include mandatory details for the supply of goods as per the schema.
● The accounting or ERP system of the business should be capable of creating a JSON of the final invoice for smooth e-invoice management.
● Integrated ERP systems, such as offline tools or third-party services, can generate JSON.
● Then the creation of a hash requires three parameters, which are GSTIN, invoice number, and financial year, ensuring invoice uniqueness. After validation, a hash converts to an Invoice Reference Number (IRN).
● One can upload JSON, along with an IRN, after its generation by the supplier, to the Invoice Registration Portal (IRP). This upload is done via direct upload, GSP, or API-based applications.
● IRP validates the data, generates the IRN if not already provided, and ensures no duplicate IRN exists in GST Central Registry.
● Once validated, IRP digitally signs the invoice, embeds a QR code, and returns a signed e-invoice JSON to the supplier for proper e-invoice management.
● If ERP and IRP integrate, the system can automatically fetch and print a signed invoice with the IRN and QR code.
● The system shares validated e-invoice data with the e-way bill system and GST system to prefill transport details (Part-A) and GSTR-1.
● After this, buyers can see data on a real-time basis in their GSTR-2A for faster Input Tax Credit (ITC) reconciliation, enhancing transparency and compliance.
● As of August 1, 2023, e-invoicing compliance is mandatory for businesses with a turnover exceeding ₹5 crores. This reinforces the need for efficient e-invoice management systems.
Key Benefits of E-Invoicing

As e-invoicing management is mandatory, businesses enjoy real benefits. These advantages are as follows:
- E-way bill generation becomes easy, as it only requires the taxpayer to enter details of their vehicle.
- It also allows for real-time tracking of invoices at the same time as their creation by the supplier. This invokes their ability for a quick input tax credit (ITC).
- The buyer gets a copy of the e-invoice once it is done uploading on the GST portal. This helps them reconcile their order along with accepting/rejecting the invoice in real-time.
- E-invoice management becomes easier as it becomes a one-time thing for the business to do online. Moreover, the elimination of manual processing and reporting leads to effort and time savings.
- Possible human errors also decrease due to the digitalisation and automation of the whole e-invoicing process.
- Due to e-invoicing mandates, there is a reduction in financial fraud as the government has all the data.
- Digital backup provided by the QR codes resolves the issue of misplacement of the invoices.
Compliance Requirements
E-invoice management by businesses has become a mandatory process and needs to comply with certain regulations set by the government. These regulations are as follows:
This regulation was set through Notice No. 10/2023 of the Indian Taxation System in FY 2017-18.
- Businesses that have a revenue of more than ₹5 crore need to mandatorily generate an e-invoice.
- There are certain sectors and business types excluded from this mandate. They include insurance companies, banks, financial institutions, and more.
