India’s GST e-invoicing system registered nearly 40 cr invoices in first 6 month

India’s GST e-invoicing system registered nearly 40 cr invoices in first 6 month

The Indian government’s GST e-invoice system has registered over 39.81 crore e-invoices over its first six months, the government announced today. Over 37.42 lakh of these e-invoices were generated on March 31 alone, which is the highest for a single day in the last six months. Over 47 lakh recipients were involved in these transactions.

The Indian government’s e-invoice system was launched in October last year and required taxpayers whose annual aggregate turnover came in at over Rs. 500 crore to use the system. The government added businesses with turnovers over Rs. 100 crore to this on January 1, 2021. Businesses with turnover of over Rs. 50 crore will also be required to use the e-invoicing system from April 1 onwards, and it’s expected to be extended to all businesses in India eventually.

The e-invoicing system is meant to add transparency to companies’ sales reporting processes and reduce errors. A digital system is also expected to make it much more difficult for companies to file fake invoices. On the other hand, experts have said that the system may pose troubles for small and medium enterprises (SMEs), which don’t always have big technology investments. According to the revised definition of MSMEs, announced last year, the vast majority of small businesses in India fall under this ,

The government’s system requires companies to raise invoices through their own enterprise resource planning (ERP) systems and submit them to the government’s Invoice Registration Portal (IRP). The government said the National Informatics Centre (NIC) has taken “pro-active measures” to educate taxpayers about common errors in reporting their invoice. It also sends daily emails with details of these errors and telephone calls to taxpayers who are making the most errors. An invoice reference number (IRN) with a QR code will also be made available to those who submit their GST invoices.

Small firms face a daunting task as e-invoicing kicks in from April 1

Small firms face a daunting task as e-invoicing kicks in from April 1

Come April 1 and e-invoicing will be mandatory for business-to-business (B2B) transactions for taxpayers having a turnover of over Rs 50 crore from April 1, 2021.

At present, issuing electronic invoices is mandatory for businesses with a turnover of Rs 100 crore and more.

E-invoicing replaces the physical invoice and will soon replace the existing eway bill system, and taxpayers will not have to generate separate e-way bills.

The challenges

However, small firms may find it challenging to comply with the new norms.

Small businesses in small towns may face some difficulties with technology-led business processes.
A business needs to validate mandatory invoice information before uploading it to e-invoice systems to avoid rejections, otherwise, they may have to spend more time.

Firms will need to be vigilant while generating e-invoice as there are restrictions with the cancellation of the invoice, which must be carried out within the same day of the transaction.

How does e-invoicing work?

E-invoicing replaces the physical invoice and will soon replace the existing e-way bill system, and taxpayers will not have to generate separate e-way bills.

Under e-invoicing, taxpayers have to generate invoices on their internal systems (ERP/accounting/billing software) and then report them online to the Invoice Registration Portal (IRP).

The IRP will validate the information provided in the invoices and return the digitally signed e-invoices with a unique ‘Invoice Reference Number (IRN)’ along with a QR Code to the taxpayer.

Gaming the system

Small businesses use informal sales invoices to under-report turnover, which will be curbed by the move.

E-invoicing makes it difficult to show lower retail sales as the wholesale purchases are already reported to the government. The tax authorities can seek an explanation for the mismatch in wholesale buys and the final sales. If the purchases are higher and sales are lower, the taxman can ask the business to show inventory.


The government expects e-invoicing to bring other major advantages, such as improving the payment cycle for industry and giving a boost to invoice-based lending to MSMEs.

Last month, the board had exempted non-banking financial companies, insurance companies, banks and financial institutions, and exports from

using dynamic quick response or QR codes on e-invoices issued to consumers. Exports have been exempted from the QR code requirement since such shipments are treated as business-to-business supplies. The board had notified the mandatory use of dynamic QR codes on such invoices issued by companies with an aggregate turnover of more than Rs 500 crore in March last year.

GST: NIC issues list of GSTINs on whom E-Invoicing is Mandatory

The National Informatics Centre (NIC) has issued a list of GSTINs dated January 27, 2021, for whom e-invoicing shall be mandatory.

There are 73308 GSTNs who are enlisted by the NIC for whom it is mandatory for the taxpayer to upload the invoice details and register supply transaction on the Government Invoice Registration Portal.

‘E-invoicing’ or ‘electronic invoicing’ is a system where the taxpayer will upload his invoice details and register his supply transaction on the Government Invoice Registration Portal (IRP) and get the Invoice Reference Number (IRN) generated by the IRP system.

The taxpayer will first prepare and generate his invoice using his ERP/accounting system or manually and then upload these invoice details to IRP and get the unique reference number, known as IRN.

It is noteworthy that the e-invoice does not mean preparation or generation of taxpayer’s invoice on the government portal. It is only intimating the government portal that invoice has been issued to the buyer, by registering that invoice on the government portal.

GST Network issues FAQs on einvoicing scheme ahead of Oct 1 launch

GST Network issues FAQs on einvoicing scheme ahead of Oct 1 launch

E-invoicing will not be applicable for business-to-consumer supplies or import bills of entries, while special economic zone units, banking companies, insurers, goods transport agencies and passenger transport companies will be exempt from issuing them.

The GST Network issued clarifications through frequently asked questions on Monday, ahead of the October 1 launch of the scheme for businesses with more than Rs 500 crore turnover. The scheme will introduce a standard invoicing standard for all companies.

“Businesses will continue to issue invoices as they are doing now. Necessary changes on account of e-invoicing requirement to enable reporting of invoices to Invoice Registration Portals (IRP) and obtain Invoice Reference Number (IRN), will be made by ERP or accounting and billing software providers in their respective software,” the IT backbone provider of GST said.

Businesses will need to get the updated version having this facility, GTSN clarified. A dedicated mobile app to scan and verify validity of e-invoice quick response (QR) code will be provided by the government.

“These FAQs not only clarify the key doubts of the industry on the subject matter, but also throw light on the modus-operandi of e-invoicing system,” said Abhishek Jain, tax partner .

E-invoices will be needed for business to business transactions, for exports, credit and debit notes. Suppliers of services by way of admission to exhibition of cinematograph films in multiplex screens will also need e-invoicing.

E-invoicing will enable auto-reporting of invoices into GST return, auto-generation of e-way bills, facilitate standardisation and inter-operability leading to reduction of disputes among transacting parties, improve payment cycles, reduction of processing costs and thereby greatly improving overall business efficiency.

New GST registrations hit by lockdown: Industry Insider

New GST registrations hit by lockdown: Industry Insider

New registrations under goods and service tax (GST) have been getting delayed to as much as 60 days or more during the lockdown period, compared to the regular turn-around time of about a week, said industry insiders.

While several applicants have faced delays going up to a few weeks, some of the applications filed before the lockdown began on March 25 are yet to be issued registration numbers. The issue, which is being faced by taxpayers across different states, has been raised by many businesses with the Central Board of Indirect Taxes and Customs (CBIC).

Besides new businesses starting up, interim resolution professionals (IRPs) or resolution professionals managing companies undergoing corporate insolvency resolution have been grappling with getting new registrations. Rules mandate IRPs to file for fresh registrations in all states where the company was earlier registered.

“Delay in grant of registration is acting as an active restraint for IRP/RP’s appointed under IBC laws, slowing the revival process for debt laden companies,” said Rajat Mohan, senior partner at AMRG Associates.

Last week, CBIC enabled a separate registration facility for IRPs on the GST portal.

According to officials, the delay in issuing new registration numbers has been due to far fewer number of tax officers across various jurisdictions having remote or virtual private network (VPN) access to process the applications.

“In many places the jurisdictional officers of the area where a business is situated are working from home, and may not have VPN access or digital signature certificates,” said an official, asking not to be named.

GST Network had said in April that it had provided secured access to over 1700 tax officers in 18 states and union territories to work remotely. Over 10,000 new registrations were issued between March 25 and April 3, it had said. GSTN did not respond to ET’s queries on new registrations post this period.

CBIC enables Facility for Registration of Insolvency Resolution Professionals on GST Portal

CBIC enables Facility for Registration of Insolvency Resolution Professionals on GST Portal

The Central Board of Indirect Taxes and Customs ( CBIC ) has enabled the facility for registration of Insolvency Resolution Professionals/ Resolution Professionals (IRPs/RPs) on the GST Portal.

Insolvency Resolution Professionals/ Resolution Professionals (IRPs/RPs), appointed to undertake corporate insolvency resolution proceedings for Corporate Debtors, in terms of Notification. No 11/2020-CT, dated 21st March 2020 can apply for a new registration on GST Portal, on behalf of the Corporate Debtors, in each of the States or Union Territories, on the PAN and CIN of the Corporate Debtor, where the corporate debtor was registered earlier, within thirty days of their appointment as IRP/RP.

They should select the Reason for Registration as “Corporate Debtor undergoing the Corporate Insolvency Resolution Process with IRP/RP” from the drop-down menu.

The date of commencement of business for IRP/RPs will be the date of their appointment. Their compliance liabilities will also come into effect from the date of their appointment.

The person appointed as IRP/RP shall be the Primary Authorized Signatory for the newly registered Company.

In the Principal Place of business/ Additional place of business, the details as specified in the original registration of the Corporate Debtors are required to be entered.

The new registration application shall be submitted electronically on GST Portal under DSC of the IRP/RP
The new registration by IRP/RP will be required only once. In case of a change in IRP/RP, after an initial appointment, it would be deemed to be a change of authorized signatory and not an appointment of a distinct person requiring a fresh registration.

In cases where the RP is not the same as IRP, or in cases where a different IRP/RP is appointed midway during the insolvency process, the change in the GST system may be carried out by a non- core amendment in the registration form.

The change in Primary Authorized Signatory details on the portal can be done either by the authorized signatory of the Company or by the concerned jurisdictional officer (if the previously authorized signatory does not share the credentials with his successor) on request of IRP/RP.

CBIC issues clarification on GST Compliance Requirements

CBIC issues clarification on GST Compliance Requirements

The Central Board of Indirect Taxes and Customs (CBIC), on Wednesday, issued the clarification in respect of certain challenges faced by the registered persons in the implementation of provisions of Goods and Service Tax (GST) Laws.

The circular was issued addressing the Principal Chief Commissioners of Central Tax and the Principal Director Generals / Director Generals while issuing clarification on various challenges.

As per the circular, Interim Resolution Professional (IRP) or Resolution Professional (RP) is now required to obtain registration within thirty days of the appointment of the IRP/RP or by June 30, 2020, whichever is later.

“IRP/RP would not be required to take a fresh registration in those cases where statements in FORM GSTR-1 under section 37 and returns in FORM GSTR-3B under section 39 of the CGST Act, for all the tax periods prior to the appointment of IRP/RP, have been furnished under the registration of Corporate Debtor (earlier GSTIN),” the circular further clarified.

The clarification pertaining to an amendment in the registration form provides that such a change would need and only change of authorized signatory which can be done by the authorized signatory of the Company who can add IRP /RP as a new authorized signatory or failing that it can be added by the concerned jurisdictional officer on request by IRP/RP.

“The requirement of exporting the goods by the merchant exporter within 90 days from the date of issue of tax invoice by the registered supplier gets extended to 30th June, 2020, provided the completion of such 90 days period falls within 20.03.2020 to 29.06.2020,” the circular stated while addressing other COVID-19 related representations.

CBIC clarifies on issues under GST Law for Companies under IBC

CBIC clarifies on issues under GST Law for Companies under IBC

The Central Board of Indirect Taxes and Customs ( CBIC ) has issued clarifications in respect of issues under GST law for companies under the Insolvency and Bankruptcy Code, 2016 (IBC) in connection with the notification issued on  Saturday.

As per the Code, no coercive action can be taken against the corporate debtor for dues of the period prior to insolvency commencement date and such dues shall be treated as ‘operational debt’ for which claims may be filed by the PO before the NCLT in accordance with the provisions of IBC.

“The tax officers shall seek the details of supplies made/received and total tax dues pending from the corporate debtor to file the claim before the NCLT. Moreover, section 14 of the IBC mandates the imposition of a moratorium period, wherein the institution of suits or continuation of pending suits or proceedings against the corporate debtor is prohibited,” the CBIC Circular said.

Regarding the cancellation of GST registration of corporate debtor, the circular clarified that registration of an entity for which CIRP has been initiated should not be cancelled. However, the Proper Officer may suspend the registration. In case of cancellation of registration of an entity undergoing CIRP within the permitted time, the Circular advises that appropriate steps should be taken.

According to the circular, IRP/RP are not bound to file returns for the pre-CIRP period as the Code does not impose an obligation on them to comply with all legal requirements for period after the Insolvency Commencement Date.

For the purpose of the notification issued on Saturday, the corporate debtor who is undergoing CIRP is to be treated as a distinct person of the corporate debtor and shall be liable to take a new registration in the appropriate State/UT, the circular said.

“Further, IRP/RP appointed prior to the said notification shall take GST registration within thirty days of issuance of the said notification, with effect from date of his appointment as IRP/RP,” it added.

As specified in the Notification, it is mandatory for the IRP/RP to file returns under section 40 of the GST Act for the period it takes registration till the date on which registration has been granted.

With regard to the procedure for availing input tax credit for invoices issued to registered persons where IRP/RP has been appointed before issuance of NN 11/2020, the circular further clarified that the exception to the procedure stated under R. 36(4) as has been provided under Notification No. 11/2020 C.T. dated 21.03.2020 shall apply only for filing the first return. 

It was further clarified that the claim of refund of deposit in the cash ledger deposited by IRP/RP of erstwhile registration of the corporate debtor from the date of notification specifying the special procedure for corporate debtors undergoing CIRP, shall be available for refund to the erstwhile registration under the head refund of cash ledger, even though the relevant FORM GSTR-3B/GSTR-1 is not filed for the said period.

E-invoicing Structure, as Envisioned by GSTN

E-invoicing Structure, as Envisioned by GSTN

e-invoicing Structure

The government has recently released a blueprint for implementing the E-invoicing system all over India, which proposes a working model as well as a standard format for the generation of E-invoices.

We shall look into the fundamentals of E-invoicing, to understand its mechanics in a better way.

The Two Important Components of the E-invoicing Model

The E-invoicing working pattern has been agreed upon globally with some minor variations in the mode of implementation. In India, it comprises of two essential components as given below:

  1. Invoice Registration Portal (IRP) – The invoices, credit notes, and debit notes which are generated by the taxpayers, should be registered on the IRP, which subsequently generates a unique reference number known as the Invoice Reference Number (IRN), a QR code, and a digital signature for these items. In fact, an invoice will be valid for the purpose of Input Tax Credit, refund, etc., only if it is registered on the IRP
  2. A standard format for the E-invoice – This standard pattern comprises of data fields and the necessary specifications. It is highly recommended for the businesses/taxpayers to upgrade their systems so as to follow this E-invoice format which enables seamless interoperability as well as data exchange all through the system.

The E-invoice Standard

The standardized E-invoice format recommended for India has been formulated in accordance with the global practices and the industry requirements for businesses in India. Further, this format has been confirmed after consulting with the respective trade authorities, the Institute of Chartered Accountants of India (ICAI), and also as per the opinions from the public.

There are around 120 fields, out of which about 50 are to be uploaded mandatorily on the Invoice Registration Portal for attaining the reference number as well as the digital signature.


Compulsory Non-compulsory Total Scope
Details of Invoice




Recognizing the distinctiveness and nature of invoices like the invoice number, type, date, etc., and also the IRP-generated details like the IRN
Details of Items




Details of line items like quantity, HSN, tax rate, etc.

Invoice Reference Details

2 8


Provides reference for previously generated or supplementary documents for the invoice
Additional Details of Items




Extra details which are related to line items like batch, barcode, serial numbers, etc.

Details of the Suppliers

5 5


GSTIN and address of the suppliers
Details of the Buyers




GSTIN and address of the buyers
‘Ship To’ Details




Address and other information like mode of supply, type of transaction, etc.

‘Dispatch From’ Details

4 4


Address and other information like E-commerce operator through which it was dispatched, state, etc.
*Details of Supporting Documents




The URLs which support the documentation, if any
*Payment Details




Payment terms, account information, etc.
Total 49 68 117

These sections are non-compulsory. If used, the mandatory fields are highly recommended. For other sections, ‘compulsory’ indicates that it is essential for registering on the IRP. In the case of line item, the data would repeat for each of these.

The E-invoicing Workflow

After the taxpayers generate the invoice using their respective accounting/ERP systems, the procedure of getting it registered with the government on the IRP, should be carried out.

There exists two components for the E-invoicing workflow namely,

  • The communication between the government and the taxpayers
  • The communication between GST, E-way bill system, and the IRP

Now let us look into the details of these two E-invoicing components.

The communication between the government and the taxpayers

The taxpayers are required to upload the compulsory fields from the invoices to the IRP in the JSON format. Further, there is provision to upload it through different methods like offline tools, GSPs (GST Suvidha Providers), web portal, mobile app, SMS, and via direct API.

Apart from providing a standard format for E-invoice, the government has also offered a model in which a unique IRN would be generated, which is technically referred to as ‘hash’, using SHA-256. Although the taxpayers could generate the IRN using their respective systems, the invoice would be valid only if it is registered with the IRP. The IRN thus generated along with the digital signature and QR code, would be reverted to the taxpayers through the same channel.

The communication between GST, E-way bill system, and the IRP

Considering the high volume of transactions on the IRP system while getting the invoice registered, the IRP comes with multiple nodes known as ‘Registrars’. The taxpayers have the option to register their invoices via any of these Registrars, and further, the latter preserves the data for the past 24 hours.

The IRP system is connected to the GST system, which acts as the repository of all IRNs, so as to ensure that there is no duplication of records. This arrangement also enables the populating of GST ANX-1 for the suppliers. Further, the E-invoice data is made available in the E-way bill system, and the transporters/taxpayers would just have to update the information on Part B in order to obtain a valid E-way Bill Number.

In fact, the taxpayers would have to upload the invoice data only once to the IRP system, wherein, the GST and E-way bill requirements would be dealt with.

To conclude, the basics of the E-invoice standard has been dealt with in detail here, which helps you to understand the entire process in a better manner.

E-Invoicing Under GST – Brief Introduction to E-Invoicing System

E-Invoicing Under GST – Brief Introduction to E-Invoicing System

E-Invoicing Under GST

The GST Council has approved introduction of ‘E-invoicing’ or ‘electronic invoicing’ in a phased manner for reporting of business to business (B2B) invoices to GST System, starting from 1st January 2020 on voluntary basis. Since there was no standard for e-invoice existing in the country, standard for the same has been finalized after consultation with trade/industry bodies as well as ICAI after keeping the draft in public place. Having a standard is a must to ensure complete inter-operability of e-invoices across the entire GST eco-system so that e-invoices generated by one software can be read by any other software, thereby eliminating the need of fresh data entry – which is a norm and standard expectation today. The machine readability and uniform interpretation is the key objective. This is also important for reporting the details to GST System as part of Return. Apart from the GST System, adoption of a standard will also ensure that an e-invoice shared by a seller with his buyer or bank or agent or any other player in the whole business eco-system can be read by machines and obviate and hence eliminate data entry errors.

The GST Council approved the standard of e-invoice in its 37th meeting held on 20th Sept 2019 and the same along with schema has been published on GST portal. Standards are generally abstruse and thus an explanation document is required to present the same in common man’s language. Also, there are lot of myth or misconception about e-Invoice. The present document is an attempt to explain the concept of e-invoice, how it operates and basics of standards. It also contains FAQs which answer the questions raised by people who responded to the draft e-invoice standard used for public consultation. It is expected that the document will also be useful for the taxpayers, tax consultants and the software companies to adopt the designed standard.

1. What is e-invoice?

If an invoice is generated by a software on the computer or Point of Sales (PoS) machine then does it become an e-invoice? Is e-invoice as a system where taxpayers can generate the invoices centrally? Many such questions are raised when e-invoice gets discussed.  

E-invoice does not mean generation of invoices from a central portal of tax department, as any such centralization will bring unnecessary restriction on the way trade is conducted. In fact, taxpayers have different requirements and expectation, which can’t be met from one software generating e-invoices from a portal for the whole country.  Invoice generated by each software may look more or less same, however, they can’t be understood by another computer system even though business users understand them fully. For example, an Invoice generated by SAP system cannot be read by a machine which is using ‘Tally’ system. Likewise there are hundreds of accounting/billing software which generate invoices but they all use their own formats to store information electronically and data on such invoices can’t be understood by the GST System if reported in their respective formats. Hence a need was felt to standardize the format in which electronic data of an Invoice will be shared with others to ensure there is interoperability of the data. The adoption of standards will in no way impact the way user would see the physical (printed) invoice or electronic (ex pdf version) invoice. All these software would adopt the new e-Invoice standard wherein they would re-align their data access and retrieval in the standard format. However, users of the software would not find any change since they would continue to see the physical or electronic (PDF/Excel) output of the invoices in the same manner as it existed before incorporation of e-Invoice standard in the software. Thus the taxpayer would continue to use his accounting system/ERP or excel based tools or any such tool for creating the electronic invoice as s/he is using today.

To help small taxpayers adopt e-invoice system, GSTN has empaneled eight accounting & billing software which provide basic accounting and billing system free of cost to small taxpayers. Those small taxpayers who do not have accounting software today, can use one of the empaneled software products, which come in both flavors, online (cloud based) as well as offline (installed on the computer system of the user).

2. e-Invoice and Tax Department

The e-invoice system being implemented by tax departments across the globe consists of two important parts namely,

     a) Generation of invoice in a standard format so that invoice generated        on one system can be read by another system.

     b) Reporting of e-invoice to a central system.

The basic aim behind adoption of e-invoice system by tax departments is ability to pre-populate the return and to reduce the reconciliation problems. Huge increase in technology sophistication, increased penetration of Internet along with availability of computer systems at reasonable cost has made this journey possible and hence more than 60 countries are in the process of adopting the e-invoice.

GST Council has given the responsibility to design the standard of e-invoice and update the same from time to time to GSTN which is the custodian of Returns and invoices contained in the same. Adoption of e-invoice by GST System is not only part of Tax reform but also a Business reform as it make the e-invoices completely inter-operable eliminating transcription and other errors.

3. Other derived benefits of introduction of e-invoice from GST perspective




Better taxpayer services

• One time reporting on B2B invoice data in the form it is generated to reduce reporting in multiple formats (one for GSTR-1 and the other for e-way bill).

• To generate Sales and purchase register (ANX-1 and ANX-2) from this data to keep the Return (RET-1 etc.) ready for filing under New Return. e-Way bill can also be generated using e-Invoice data

• It will become part of the business process of the taxpayer

• Substantial reduction in input credit verification issues as same data will get reported to tax department as well to buyer in his inward supply (purchase) register.

• On receipt of info thru GST System as buyer can do reconciliation with his Purchase Order and accept/reject in time under New Return

Reduction of tax evasion

• Complete trail of B2B invoices

• System level matching of input credit and output tax

Efficiency in tax administration

• Elimination of fake invoices

Generation of e-invoice will be the responsibility of the taxpayer who will be required to report the same to Invoice Registration Portal (IRP) of GST, which in turn will generate a unique Invoice Reference Number (IRN) and digitally sign the e-invoice and also generate a QR code. The QR Code will contain vital parameters of the e-invoice and return the same to the taxpayer who generated the document in first place. The IRP will also send the signed e-invoice to the recipient of the document on the email provided in the e-invoice.   

Note: To begin with, there will be only one IRP, but more IRPs will be added to provide higher availability, redundancy, speed and a diversified and distributed service to tax payers with a choice.

4. What type of documents are to be reported to GST System?

While the word invoice is used in the name of e-invoice, it covers other documents that will be required to be reported to IRP by the creator of the document:

  • Invoice by Supplier
  • Credit Note by Supplier
  • Debit Note by Supplier
  • Any other document as required by law to be reported by the creator of the document

4. What will be the workflow involved?

The flow of the e-invoice generation, registration and receipt of confirmation can be logically divided into two major parts.  

  1. The first part being the interaction between the business (supplier in case of invoice) and the Invoice Registration Portal (IRP).
  2. The second part is the interaction between the IRP and the GST/E-Way Bill Systems and the Buyer.  


The two parts of the workflow are depicted diagrammatically below and followed up with an explanation of the steps involved. As the process evolves and system matures the same would be intercommunicated between buyer’s software and seller’s software, banking systems etc.

Part A: Flow from Supplier (commonly known as seller) to IRP.  

Step 1 is the generation of the invoice by the seller in his own accounting or billing system (it can be any software utility that generates invoice including those using excel or GSTN’s provided Offline Utility).  The invoice must conform to the e-invoice schema (standards) that is published and have the mandatory parameters.  The optional parameters can be according to the business need of the supplier.  The supplier’s (seller’s) software should be capable to generate a JSON of the final invoice that is ready to be uploaded to the IRP. The IRP will only take JSON of the e-invoice.


Note: Seller should have a utility that will output invoice data in JSON format, either from his accounting or billing software or his ERP or excel/word document or even a mobile app.  Those who do not use any accounting software or IT tool to generate the invoice, will be provided an offline tool to key-in data of invoice and then submit the same. The small and medium size taxpayers (having annual turnover below Rs 1.5 Crores) can avail accounting and billing system being offered by GSTN free of cost. 


Step 2 is to generate the unique Invoice Reference Number (IRN) (in technical terms hash of 3 parameters using a standard and well known hash generation algorithm e.g. SHA256). This is an optional step. The seller can also generate this and upload along with invoice data. The 3 parameters which will be used to generate IRN (hash) are:

  1. Supplier GSTIN,
  2. Supplier’s invoice number and,
  • Financial year (YYYY-YY).  (The IRN or hash generation algorithm will be prescribed by GSTN in the e-invoice standard).  

Step 3 is to upload the JSON of the e-invoice (along with the hash, if generated) into the IRP by the seller.  The JSON may be uploaded directly on the IRP or through GSPs or through third party provided Apps.    

Step-4: The IRP will also generate the hash and validate the hash of the uploaded json, if uploaded by the supplier. The IRP will check the hash from the Central Registry of GST System to ensure that the same invoice from the same supplier pertaining to same Fin Year is not being uploaded again. On receipt of confirmation from Central Registry, IRP will add its signature on the Invoice Data as well as a QR code to the JSON. The QR code will contain GSTIN of seller and buyer, Invoice number, invoice date, number of line items, HSN of major commodity contained in the invoice as per value, hash etc. The hash computed by IRP will become the IRN (Invoice Reference Number) of the e-invoice.  This shall be unique to each invoice and hence be the unique identity for each invoice for the entire financial year in the entire GST System for a taxpayer. [GST Systems will create a central registry where hash sent by all IRPs will be kept to ensure uniqueness of the same].

Step 5 will involve sharing the uploaded data with GST and e-way bill system. More details are given in Part-B below.

Step 6 will involve returning the digitally signed JSON with IRN back to the seller along with a QR code. The registered invoice will also be sent to the seller and buyer on their mail ids as provided in the invoice.  

Part B: Flow from IRP to GST System/E-Way Bill System & Buyer


The following diagram shows how e-Invoice data would be consumed by GST System for generation of e-way bill or populating relevant parts GST Returns, stated in Step-5 above.

Step 5 (a) will be to share the signed e-invoice data along with IRN (same as that has been returned by the IRP to the seller) to the GST System as well as to E-Way Bill System.

Step 5b The GST System will update the ANX-1 of the seller and ANX-2 of the buyer, which in turn will determine liability and ITC.  

Step 5c E-Way bill system will create Part-A of e-way bill using this data to which only vehicle number will have to be attached in Part-B of the e-way bill.

Note 1: The e-invoice standardized schema has mandatory and optional items.  The e-invoice shall not be accepted in the GST System unless all the mandatory items are present.  The optional items are to be used by the seller and buyer as per their business need to enforce their business obligations or relationships.

Note 2: Seller may send his e-invoice for registration to more than one registrar.  But the GST system and IRP will perform a de-duplication check with central registry to ensure that the IRN that is generated is unique for each invoice.  Therefore, the IRP shall return ONLY ONE registered IRN for each invoice to the seller.  In case of multiple registrars (more than one IRPs) only one IRP will return a valid IRN to the seller. Except one, all other IRPs will reject the request of registration.

Note 3:  The QR code will enable quick view, validation and access of the invoices from the GST system from hand held devices.

6. Direct Invoice Generation on IRP (Invoice Registration Portal)

Many people think that e-invoice will be generated from government’s tax portal. This is a myth and invoices will continue to be generated using an Accounting or a billing software, keeping in view the varied need of item master, buyer master, UQC etc. along with sub-second response from IR Portal (IRP). Thus, direct creation/generation of e-invoice from GST portal or any other government portal is not envisaged/planned.

Small taxpayers can use one of the eight free accounting/billing software currently listed by GSTN. Also, GSTN will provide Offline Tool where data of an invoice, generated on paper can be entered which in turn will create JSON file for uploading on the IRP. Taxpayers can also use one of the commercially available accounting/billing software for this purpose. All accounting and billing software companies are being separately asked to adopt the e-invoice standard so that their users can generate the JSON from the software and upload the same on the IRP.

7. Features of e-invoice system

The Format of Unique Invoice Reference Number (IRN):

The unique IRN will be based on the computation of hash of GSTIN of generator of document (invoice or credit note etc.), Year and Document number like invoice number.  This hash will be as published in the e-invoice standard and unique for this combination. This way hash will always be the same irrespective of the registrar who processes it. The hash could also be generated by the taxpayers based on above algorithm. The providers of accounting and billing software are being separately asked to incorporate this feature in their product.  One can pre-generate and print it on the invoice book, however, the same will not make the invoice valid unless it is registered on the portal along with invoice details.

Note: The hash algorithm that is to be used by the taxpayers has been specified in the e-invoice standard that is published.  The hash will be the IRN.

To ensure deduplication, the registrar will be required to send the hash to Central Registry of GST System to confirm whether the same has been reported already. In case it has been reported by another registrar (as and when more registrars – IRPs – are added) and the Central Registry already has the same IRN, then the registrar will reject the registration and inform the sender. Only unique invoices from a taxpayer will be accepted and registered by the registrar.

Digital Signing by e-Invoice Registration Portal: The invoice data will be uploaded on the IRP (Invoice Registration Portal), which will also generate the hash in order to verify it and then digitally sign it with the private key of the IRP. In case the taxpayer submits hash also along with invoice data, the same will be validated by IRN system. The IRP will sign the e-invoice along with hash and the e-invoice signed by the IRP will be a valid e-invoice and used by GST/E-Way bill system.   

QR Code: The IRP will also generate a QR code containing the unique IRN (hash) along with some important parameters of invoice and digital signature so that it can be verified on the central portal as well as by an Offline App. This will be helpful for tax officers checking the invoice on the roadside where Internet may not be available all the time. The web user will get a printable form with all details including QR code.  The QR code will consist of the following e-invoice parameters:

  1. GSTIN of supplier
  2. GSTIN of Recipient
  3. Invoice number as given by Supplier
  4. Date of generation of invoice
  5. Invoice value (taxable value and gross tax)
  6. Number of line items.
  7. HSN Code of main item (the line item having highest taxable value)
  8. Unique Invoice Reference Number (hash)

The offline app will be provided on the IRP for anyone to download to authenticate the QR code of the invoice offline and its basic details. However, to see the whole invoice, one will have to connect to the portal and verify and see the details online. The facility to download entire invoice will be provided to tax officers, the way it is currently available under E-way bill system.

Note 4:  The facility of QR code verification will be made available only through the GST System and not the IRP.  This is because the IRP will not have the mandate to store invoices for more than 24 hours.  In order to achieve speed and efficiency, the IRP will be a lean and focused portal for providing invoice registration and verification service, IRN and the QR codes.  Hence, storing of the invoices will not be a feature of the IRP.

Multiple Registrar for IRN System: Multiple registrars (IRPs) will be put in place to ensure 24X7 operations without any break. To start with, NIC will be the first Registrar. Based on experience of the trial more registrars will be added.

Standardization of Invoice: A technical group constituted by the GST Council Secretariat has drafted standards for e-invoice after having industry consultation. The e-invoice schema and template, as approved by the GST Council, are available at


Modes for getting invoice registered: Multiple modes will be made available so that taxpayer can use the best mode based on his/her need. The modes given below are envisaged at this stage under the proposed system for e-invoice, through the IRP (Invoice Registration Portal):

  1. Web based,
  2. API based,
  3. SMS based,
  4. mobile app based,
  5. offline tool based and
  6. GSP based.

API mode: Using API mode, the big tax payers and accounting software providers can interface their systems and pull the IRN after passing the relevant invoice information in JSON format. API request will handle one invoice request at time to generate the IRN.  This mode will also be used for bulk requirement (user can pass the request one after the other and get the IRN response within fraction of second) as well. The e-way bill system provides the same methodology.

Printing of Invoice

The taxpayer can continue to print his paper invoice as he is doing today including logo and other information. E-invoice schema only mandates what will be reported in electronic format to IRP.

General Questions on e-invoice system

Generic questions on e-invoice

1. Will businesses now be required to generate e-invoices on the GST portal or the e-invoice portal or the IRN portal?

a. No.  

b. Businesses will continue to generate e-invoices on their internal systems – whether ERP or their accounting / billing systems or any other application.

c. The e-invoicing mechanism only specifies the invoice schema and standard so as to be inter-operable amongst all accounting/billing software and all businesses.

2. Please clarify whether there the current e-invoice schema is for the invoice to be issued by Govt or has to be maintained in the IT system by the tax payer?

b. IRN (Invoice Reference Number) will be the hash generated by the IRP.  

c. The registered invoice will be valid to be used by the business.

2. Will it be possible for bulk uploading of invoices for e-invoicing as well?

a. Invoices have to be uploaded on IRP one at a time.

b. The IRP will be able to handle a large sequence of invoices for registration and validate them. Essentially bulk upload will be required by large taxpayers who generate large number of invoices. Their ERP or accounting system will have to be designed in such a way that it makes request one by one. For the user, it will not make any difference.
