What is E-Invoicing and How It Works ?

What Is E-Invoicing?

E-invoicing under GST is a system in which specified business invoices are electronically reported to an Invoice Registration Portal (IRP) for authentication. It is primarily applicable to B2B and export transactions by businesses covered by the e-invoicing mandate.

The business first creates the invoice using its accounting or billing software. The required invoice details are then submitted to the IRP. After successful validation, the IRP generates a unique Invoice Reference Number (IRN) and a digitally signed QR code, which become part of the e-invoice.

In simple terms, e-invoicing does not mean creating an invoice on the GST portal. It means registering an already generated invoice with the IRP in the prescribed format so that it is authenticated and can be used for GST compliance.

What Is Not Considered an E-Invoice?

An invoice is not considered an e-invoice under GST simply because it is created digitally, sent by email, or generated as a PDF. For a transaction covered under the e-invoicing mandate, the invoice details must be reported to an Invoice Registration Portal (IRP) and receive a valid Invoice Reference Number (IRN) and digitally signed QR code. The following are not treated as e-invoices:

• A regular invoice created in accounting or billing software but not registered on the IRP
• A PDF, Excel, Word, or scanned invoice that does not have a valid IRN
• A B2C invoice issued directly to an unregistered customer, as B2C transactions are currently outside the GST e-invoicing mandate
• A bill of supply, which is not covered under the e-invoice system
• Other documents that are outside the prescribed e-invoice document types

Currently, the e-invoicing system covers specified tax invoices, debit notes, and credit notes for B2B and export transactions. Therefore, creating or sharing an invoice electronically does not by itself make it an e-invoice.

Types of E-Invoicing Systems

Under GST, there is a common e-invoicing framework, but businesses can generate and report e-invoices through different methods depending on their invoice volume and accounting setup.

1. Web Portal-Based E-Invoicing

Businesses with a small number of invoices can enter invoice details directly through the web form available on an authorised Invoice Registration Portal (IRP). This method does not require any major software integration.

2. Excel or Bulk Upload-Based E-Invoicing

Businesses can prepare multiple invoice details using the prescribed Excel utility or supported file format and upload them to the IRP in bulk. This is useful when several invoices need to be registered together.

3. JSON Upload-Based E-Invoicing

Invoice details can also be prepared in the prescribed e-invoice JSON format and uploaded to the IRP. Once the data is successfully validated, the system generates the Invoice Reference Number (IRN) and signed QR code.

4. API-Based E-Invoicing

Businesses with a high volume of transactions can integrate their ERP, accounting, or billing software with the IRP through APIs. Invoice details are submitted electronically from the software to the IRP, enabling faster, more automated e-invoice generation.

The right method depends mainly on the number of invoices a business generates and the level of automation it requires. Businesses with fewer invoices may find portal or bulk-upload methods sufficient, while businesses processing large transaction volumes generally benefit from API-based integration.

How Does E-Invoicing Work?

E-invoicing works by generating and sending invoices digitally, directly linked to the government’s GST portal. The process begins with the supplier creating an invoice using software or an e-invoicing system. After the invoice is prepared, it is submitted to the GST portal for validation. The portal checks for errors and ensures compliance with tax regulations. Once validated, a unique Invoice Reference Number (IRN) is generated, and a digital signature is applied to the invoice.

The e-invoice is then sent to the buyer and stored in the government’s database for record-keeping. This system simplifies invoice generation, reduces errors, and ensures timely tax payments. It also helps businesses and tax authorities track transactions, preventing fraud and making audits easier.

E-Invoicing vs. Traditional Invoicing

Traditional invoicing and e-invoicing both start with a business creating an invoice in its accounting, billing or ERP software. The key difference is what happens after the invoice is created.

In a traditional invoicing process, businesses may create invoices in different formats and separately enter or upload the same invoice data for GST returns, e-way bills and other compliance requirements. This can involve repeated data entry across different systems.

Common Challenges with Traditional Invoicing

Traditional invoicing can lead to:

• Repeated entry of the same invoice data across different systems
• Data-entry errors and invoice mismatches
• More manual work while preparing GST returns
• Separate data entry for generating e-way bills
• Difficulty exchanging invoice data between different accounting or ERP systems

How E-Invoicing Works

Under e-invoicing, businesses continue to generate invoices through their own accounting, billing or ERP software. For transactions covered under the e-invoicing mandate, the prescribed invoice details are then reported to an authorised Invoice Registration Portal (IRP).

The IRP validates the invoice data and, after successful registration, provides an Invoice Reference Number (IRN) and a digitally signed QR code.

Invoice data can be reported to the IRP using methods such as JSON upload, Excel or bulk-upload utilities, or API integration, depending on the system and IRP being used.

How E-Invoicing Improves the Process

E-invoicing creates a standard structure for exchanging invoice data and reduces the need to enter the same information multiple times. It can help businesses:

• Reduce manual data entry and related errors
• Improve invoice accuracy and standardisation
• Make invoice data easier to exchange between systems
• Improve reconciliation and invoice tracking
• Simplify GST and e-way bill compliance

How E-Invoicing Supports GST Compliance

Once an e-invoice is successfully registered, relevant invoice data is shared with the GST system and e-way bill system.

This helps auto-populate applicable details in the supplier's GSTR-1 and supports the subsequent flow of eligible invoice information to the recipient's GSTR-2B. The same invoice data can also be used for generating an e-way bill, reducing duplicate data entry. Where the required transport details are provided, the e-way bill can be generated along with the e-invoice; otherwise, the remaining details can be added separately.

In this way, e-invoicing connects invoice generation with GST reporting and e-way bill compliance while reducing repetitive manual work.

E-Invoicing Under GST in India

E-invoicing under GST is a system in which specified B2B invoices, export invoices, credit notes and debit notes are electronically reported to an authorised Invoice Registration Portal (IRP) for authentication.

The decision to introduce e-invoicing in India was taken at the 35th GST Council meeting. The system was introduced in phases, starting with larger businesses on 1 October 2020 and later expanding to businesses with lower turnover thresholds.

E-invoicing does not mean creating an invoice on the GST portal. Businesses continue to generate invoices using their accounting, billing or ERP software and then report the prescribed invoice details to an authorised IRP.

The framework for e-invoicing was introduced through amendments to the GST rules, while Notification No. 69/2019 - Central Tax notified common portals for e-invoicing.

Once the invoice details are successfully validated, the IRP generates a unique Invoice Reference Number (IRN) and a digitally signed QR code. The registered invoice data is also shared with the GST system and the e-way bill system.

This integration helps auto-populate relevant invoice details in GSTR-1 and allows the same data to be used for Part A of the e-way bill, reducing the need to enter the same information multiple times for GST compliance.

Is E-Invoicing Mandatory? GST Rules and Threshold History in India

Yes, e-invoicing is mandatory under GST for eligible registered businesses whose aggregate turnover exceeds ₹5 crore in any financial year from 2017-18 onwards. The current threshold has been applicable since 1 August 2023.

The turnover is considered on an aggregate PAN basis, meaning turnover from all GST registrations held under the same PAN is aggregated. Once a business falls under the e-invoicing requirement, all applicable B2B and export invoices, debit notes, and credit notes must be reported to an Invoice Registration Portal (IRP) to obtain an Invoice Reference Number (IRN) and a QR code.

However, certain notified categories of taxpayers are exempt from e-invoicing even if their turnover exceeds the prescribed limit.

E-Invoice Turnover Limit History in India

The government introduced e-invoicing in phases, gradually bringing smaller businesses under the system.

Therefore, a business should not check only its current year's turnover. If its aggregate turnover exceeded ₹5 crore in any financial year from 2017-18 onwards, it may be subject to the current e-invoicing requirement, subject to the notified exemptions.

Important: From 1 April 2025, taxpayers with an Aggregate Annual Turnover (AATO) of ₹10 crore or more must report eligible invoices, debit notes and credit notes to the IRP within 30 days from the document date.

Who Needs to Generate E-Invoices

Under the current GST rules, e-invoicing is mandatory for eligible registered businesses whose aggregate turnover exceeds ₹5 crore in any financial year from 2017-18 onwards, subject to the notified exemptions.

Aggregate turnover is calculated on a PAN basis across India. This means the turnover of all GSTINs registered under the same PAN must be considered together, not separately for each GST registration.

For example, if a business has three GST registrations under one PAN, their combined turnover is considered when checking the e-invoicing threshold.

If a business exceeds the prescribed turnover threshold in the current financial year, e-invoicing generally applies from the beginning of the next financial year.

Transactions Covered Under E-Invoicing

For eligible taxpayers, e-invoicing applies mainly to:

• B2B supplies made to registered persons
• Export of goods or services
• Deemed exports
• Supplies between distinct persons, such as different GSTINs of the same business
• Applicable supplies to SEZ developers
• Applicable supplies to registered government or PSU entities

E-invoicing is currently not applicable to B2C invoices issued to unregistered customers.

Documents Covered Under E-Invoicing

The following documents issued by the supplier are required to be reported to the Invoice Registration Portal (IRP) when e-invoicing applies:

• Tax invoices
• Debit notes issued under GST
• Credit notes issued under GST

Documents such as bills of supply and delivery or job-work challans are not reported under the e-invoicing system. Once an eligible document is successfully reported to the IRP, an Invoice Reference Number (IRN) and digitally signed QR code are generated for it.

Who Is Exempt from E-Invoicing

There are certain categories of registered persons for whom e-invoicing will not be applicable at the moment, regardless of their turnover. These exemptions have been notified in CBIC Notification No.13/2020 – Central Tax, which has been amended periodically:

• E-invoicing requirements do not apply to insurers, banking companies, or financial institutions, including Non-Banking Financial Companies (NBFCs).
• Goods Transport Agencies (GTAs) are also exempted from the requirements of e-invoicing. GTAs, which provide transportation services for goods, are not obligated to implement e-invoicing as per the applicable regulations.
• A registered person engaged in providing passenger transportation services is also exempt from the requirement of implementing e-invoicing under GST.
• A registered person who supplies services by way of admission to the exhibition of cinematographic films in multiplex services is also exempt from the obligation of implementing e-invoicing.
• An SEZ (Special Economic Zone) unit is exempt from the requirement of implementing e-invoicing, as specified in CBIC Notification No. 61/2020 – Central Tax.
• Government departments and local authorities are exempt from the obligation of implementing e-invoicing, as specified in CBIC Notification No. 23/2021 – Central Tax.

What's Inside an E-Invoice: Mandatory Fields, Schema & QR Code

An e-invoice contains standard invoice details in a structured format, enabling the information to be validated and exchanged electronically between different systems. The required information is defined under the GST e-invoice schema, Form GST INV-01.

Mandatory Fields in an E-Invoice

The key details required in an e-invoice include:

1. Supplier details: Name, address and GSTIN of the supplier.
2. Buyer details: Name, address and GSTIN of the recipient for applicable transactions.
3. Invoice details: Document type, invoice number and invoice date.
4. HSN code: Applicable HSN code for the goods or services supplied.
5. Invoice value: Taxable value, tax amount and total invoice value.
6. Item details: Description, quantity, unit and other applicable product or service details.
7. GST details: Applicable GST rate and CGST, SGST, IGST or cess amounts, as relevant.
8. Other applicable details: Information such as place of supply, reverse charge or export details, wherever required.
9. IRN and signed QR code: These are generated by the Invoice Registration Portal (IRP) after the invoice data is successfully validated.

Not every field in the e-invoice format is mandatory for every transaction. Some fields become mandatory only in specific situations, such as exports or certain types of supplies.

What Is the GST E-Invoice Schema (INV-01)?

Form GST INV-01 is the standard e-invoice schema prescribed under GST. It defines how invoice information should be structured when it is reported to the IRP.

The schema contains both mandatory and optional fields covering areas such as supplier and buyer details, document information, item details, tax values, payment details, references and transportation information.

The schema standardises the data format, not the visual design of the invoice. Businesses can continue using their own invoice layouts as long as the required information is correctly reported in the prescribed format.

What Information Does the E-Invoice QR Code Contain?

After successful registration, the IRP generates a digitally signed QR code containing key invoice information, including:

• Supplier GSTIN
• Recipient GSTIN
• Invoice number
• Invoice date
• Invoice value
• Number of line items
• HSN code of the main item
• Invoice Reference Number (IRN)
• IRN generation date

The QR code allows businesses and recipients to verify important e-invoice details and confirm that the invoice has been authenticated through an authorised IRP.

What Is the 64-Character IRN?

The Invoice Reference Number (IRN) is a unique 64-character hash generated by the e-invoice system after successful registration of the invoice. It is generated using the SHA-256 algorithm based on key details such as:

Supplier GSTIN + Financial Year + Document Type + Document Number

The IRN uniquely identifies the registered invoice in the GST e-invoicing system. It is generated by the IRP and is not manually created by the taxpayer.

How to Generate an E-Invoice: Step-by-Step Process

Businesses continue to create invoices in their existing accounting, billing or ERP software. E-invoicing begins when the required invoice details are reported to an authorised Invoice Registration Portal (IRP) for validation and registration.

Step 1: Create the Invoice

Generate the invoice in your accounting, billing or ERP software as usual. Make sure it contains the mandatory details required under the GST e-invoice schema (INV-01), including the supplier and buyer GSTIN, invoice number and date, HSN code, taxable value, applicable GST rate, tax amount and place of supply, wherever applicable.

Step 2: Report the Invoice Details to the IRP

Submit the invoice data to an authorised IRP using a supported method such as the web form, Excel or bulk-upload utility, JSON file upload, or API integration through accounting or ERP software.

Businesses with a high volume of invoices generally use API integration, while portal or bulk-upload methods may be more suitable for lower invoice volumes.

Step 3: IRP Validates the Invoice

The IRP checks the submitted invoice data against the prescribed schema and validation rules. It also checks whether the same invoice has already been reported.

If mandatory details are missing or the data fails validation, the invoice is rejected and must be corrected before it can be registered.

Step 4: IRN and QR Code Are Generated

After successful validation, the IRP generates a unique 64-character Invoice Reference Number (IRN), acknowledgement number and acknowledgement date. It also digitally signs the invoice data and generates a signed QR code.

The IRN is generated using key details such as the supplier GSTIN, financial year, document type and document number.

Step 5: Receive the Registered E-Invoice

The registered invoice details, including the IRN and signed QR code, are returned to the taxpayer through the selected reporting method.

The required e-invoice details and QR code can then be included on the invoice shared with the buyer.

Step 6: Invoice Data Flows to GST and E-Way Bill Systems

The registered invoice information is shared with the GST system, where relevant details can be auto-populated in the supplier's GSTR-1.

Where an e-way bill is required, the same invoice data can also be used for Part A of the e-way bill, reducing repeated data entry.

In short:

Create Invoice → Report to IRP → Validate Data → Generate IRN & QR Code → Issue E-Invoice → GST and E-Way Bill Data Flow

Time Limit to Generate E-Invoice

Until April 30, 2023, there is no specific time limit set by the GST systems or the GST law for generating e-invoices. However, starting from May 1, 2023, taxpayers with an Annual Aggregate Turnover (AATO) equal to or exceeding INR 100 crore must generate e-invoices for tax invoices and credit/ debit notes  within 7 days from the date of the invoice. Failure to comply will result in such invoices and CDNs being considered non-compliant.

For other applicable taxpayers, there is no defined time limit or period for generating e-invoices. However, it is advised for them to create e-invoices preferably a week before filing GSTR-1 returns, as it takes T+3 days for the e-invoice details to be auto-populated into GSTR-1.

On May 6, 2023, the department deferred the 7-day time limit to report old e-invoices on the IRP portals by three months. The new implementation date is yet to be announced by the department.

How to Cancel an E-Invoice

An e-invoice can be cancelled on the Invoice Registration Portal (IRP) within 24 hours of IRN generation. Cancellation may be required if the invoice was generated with incorrect details, created by mistake, duplicated, or the transaction itself was cancelled.

Only the complete e-invoice can be cancelled. Partial cancellation of individual items or values in an e-invoice is not allowed.

Steps to Cancel an E-Invoice

1. Log in to the authorised Invoice Registration Portal (IRP).
2. Open the e-invoice or IRN cancellation section.
3. Select or enter the details of the invoice you want to cancel.
4. Choose the reason for cancellation and enter the required remarks.
5. Submit the cancellation request.

Once cancelled, the IRN cannot be restored. A fresh e-invoice may need to be generated with a new invoice number where applicable.

What If an E-Way Bill Is Already Generated?

If an active e-way bill is linked to the e-invoice, the e-way bill must be cancelled first. The IRN can then be cancelled, provided the 24-hour cancellation period has not expired.

What If 24 Hours Have Passed?

After 24 hours, an e-invoice cannot be cancelled or amended on the IRP.

If the invoice has already flowed into GSTR-1, the correction should be made through the appropriate GST compliance route. Depending on the type of error, this may involve:

• issuing a credit note to reverse or reduce the invoice value or tax liability;
• issuing a debit note where additional value or tax needs to be reported; or
• correcting the invoice through the permitted GSTR-1/GSTR-1A amendment process, where applicable.

If GSTR-1 has already been filed, the original filed return cannot simply be edited. The correction needs to be reported through the appropriate adjustment or amendment in the relevant return period.

How to Verify an E-Invoice / IRN

An e-invoice can be verified using its digitally signed QR code or signed JSON file. Verification helps confirm that the invoice was authenticated by an authorised Invoice Registration Portal (IRP) and allows you to check key invoice details.

Verify Using the “Verify Signed Invoice” Option

The e-invoice portal provides a Verify Signed Invoice facility for checking the authenticity of an e-invoice.

To verify:

1. Open an authorised e-invoice portal.
2. Go to the Verify Signed Invoice option.
3. Upload the signed JSON file of the e-invoice.
4. Submit the file for verification.
5. If the digital signature and invoice data are valid, the portal will confirm that the invoice has been successfully verified.

Verify Using the QR Code

Every authenticated e-invoice contains a digitally signed QR code generated by the IRP. You can scan this QR code using the GSTN e-Services app to verify the invoice. The app can display and verify key details such as:

• Supplier GSTIN
• Recipient GSTIN
• Invoice number and date
• Invoice value
• Invoice Reference Number (IRN)
• IRN status

Cross-check these details with the invoice received and confirm that the IRN is valid. Verifying the QR code and IRN status helps identify invoices that are incorrect, unauthenticated or have been cancelled.

Is E-Invoicing Secure? Data Protection in the IRN Process

Yes, the GST e-invoicing system uses multiple security measures to protect invoice data during IRN generation and transmission. Businesses submit invoice details to an authorised Invoice Registration Portal (IRP), where the data is validated before an Invoice Reference Number (IRN) and digitally signed QR code are generated. Key security measures include:

Encrypted Data Transmission

For core e-invoice APIs, invoice data is transmitted in an encrypted format. Responses from the IRP are also encrypted, helping reduce the risk of unauthorised access while data is being exchanged between accounting software and the portal.

Authentication and Authorised Access

API access requires authorised credentials and authentication tokens. This helps ensure that invoice-related actions are performed only by approved users or systems linked to the taxpayer.

Multi-Factor Authentication

Authorised IRPs may also require Multi-Factor Authentication (MFA) for portal access. This adds an additional verification step beyond a username and password and helps protect taxpayer accounts from unauthorised logins.

Digitally Signed QR Code

After successful registration, the IRP generates a digitally signed QR code for the e-invoice. This helps recipients and tax authorities verify that the invoice was registered through an authorised IRP and check key details such as the GSTIN, invoice number, invoice date and IRN.

Consent-Based Access to Additional Data

For certain data and value-added APIs beyond the core e-invoicing functions, authorised IRPs require explicit taxpayer consent before invoice information can be stored, accessed or shared through those services.

While these controls improve the security and authenticity of e-invoices, businesses should still protect their login credentials, restrict user access and keep accounting software and devices updated. No online system can guarantee complete protection from every possible security threat.

How can e-invoicing curb tax evasion?

E-invoicing generates a unique QR code for each invoice, ensuring authenticity. It makes real-time reporting mandatory, reducing the chances of unreported or fake invoices. This transparency helps authorities track transactions more efficiently, reducing the chances of tax evasion.

Documents Covered Under E-Invoicing

The concept of e-invoice encompasses the following documents, which need to be uploaded to the IRP system by their creators:

• Invoice by Supplier
• Credit Note  by Supplier
• Debit Note by Supplier
• Any other legally required document must be uploaded to the IRP system by its creator.

Benefits of E-invoicing to Businesses

The implementation of e-invoicing initiated by GSTN brings several benefits to businesses, including:

• Data reconciliation: e-Invoicing reduces mismatch errors and resolves gaps in data reconciliation under GST, leading to more accurate reporting.
• Interoperability: e-Invoices generated on one software can be read by another, promoting interoperability and reducing data entry errors when invoices are exchanged between different systems.
• Real-time tracking: With e-invoicing, businesses can track invoices prepared by suppliers in real-time, enabling better visibility and control over the invoicing process.
• Automation of return filing: e-Invoicing under GST facilitates backward integration and automation of the   GST return   filing process. Invoice details are auto-populated in various returns, simplifying the generation of part-A of e-way bills and streamlining compliance.
• Faster availability of input tax credit: e-Invoicing expedites the availability of genuine input tax credit, allowing businesses to claim credits more efficiently and quickly.
• Reduced possibility of audits/surveys: Since transaction-level information is readily available through e-invoicing, there is a reduced likelihood of audits or surveys by tax authorities as the required information is already captured in a standardized format.
• Access to credit routes: e-Invoicing enables faster and easier access to formal credit routes, such as invoice discounting or financing, particularly beneficial for small businesses seeking working capital solutions.
• Improved customer relations: e-Invoicing under GST enhances customer relations, especially for small businesses, by ensuring compliance with large enterprises’ invoicing requirements, thus increasing opportunities for business growth.

How BUSY Simplifies E-Invoicing

BUSY integrates e-invoicing with the regular billing process, so businesses can create invoices, generate IRNs and manage related GST compliance without repeatedly entering the same invoice data on different portals.

Generate IRN and QR Code from BUSY

Once an eligible B2B or export invoice is created, its details can be sent to the Invoice Registration Portal (IRP) through BUSY. After successful validation, the generated IRN, acknowledgement details and signed QR code are brought back into BUSY and linked with the invoice.

Validate Invoice Details Before Generation

BUSY helps validate important details such as GSTIN and HSN information before e-invoice generation. Checking invoice data before it is submitted to the IRP can help reduce errors and failed e-invoice generation.

Generate E-Invoices in Bulk

For businesses processing a large number of invoices, BUSY supports bulk e-invoice generation. Users can filter vouchers by criteria such as date, party or voucher type, generate IRNs for multiple invoices, and track which e-invoices have been generated or are still pending.

Print and Share E-Invoices

After an e-invoice is registered, BUSY can print the IRN, acknowledgement details and QR code on the invoice. The registered invoice can then be printed or shared with the customer through the available invoice-sharing options.

Keep E-Invoicing Connected with GST Compliance

E-invoice data remains connected with the business's billing and GST records in BUSY. Relevant details can flow into GSTR-1, reducing duplicate data entry during return preparation.

Where an e-way bill is also required, BUSY supports generating the e-invoice and e-way bill together, subject to the required transport and transaction details being available.

Manage E-Invoice Cancellations

If an e-invoice needs to be cancelled, BUSY allows users to manage the cancellation within the permitted 24-hour IRN cancellation window, helping keep the invoice record and e-invoice status aligned.
