All About E-Invoice and Other Similar GST Instruments Imagine a system where business invoices are verified very fast, and also with leaving no room for error, that is exactly what e-invoicing under GST is there for. Introduced by the GST council, eligible businesses must upload invoices to the Invoice Registration Portal (IRP), which generates a unique Invoice Reference Number (IRN) and QR code for validation. It mainly applies to B2B transactions, exports, and other notified supplies for businesses. Alongside e-invoicing, there are other similar instruments which each play their vital role in ensuring smooth goods movement, accurate record-keeping, and GST compliance. This article is a breakdown of all that it covers, e-invoice: meaning, purpose, applicability, elements and other similar GST instruments like e-way bills, tax invoices, bill of supply, receipt vouchers, and delivery challans
What is an E-invoice under GST? E- invoice stands for electronic invoice. It means that businesses must report their invoices (bills), which are created by them, to a government-notified portal called the Invoice Registration Portal (IRP) , and after reporting to the portal, they obtain a reference number. It was introduced in the GST Council in its 37th meeting dated 20 September 2019, to revolutionise the way businesses interact with each other by enhancing ease of doing business. Businesses with a turnover of more than 5 crore must generate an e-invoice under GST. Benefits of E-invoice 1. Automation of GST reporting: Businesses only need to report their invoices on the portal once, and the same data can only be used once for GSTR1, e-way bill and other GST forms, which minimises duplicate work, avoids errors and helps buyers match invoices with their purchase orders
2. Improves business efficiency: E-invoice promotes standardisation and interoperability, which reduces disputes between transacting parties, improves payment cycles, and lowers the processing costs.
3. Minimises Tax evasion: It creates one trail of all b2b invoices together, allowing the system to match with input credit with the output tax.
4. Fraud Protection: It eliminates fake invoices, which helps in regulating transparency and honesty in the GST system
Applicability of e-invoicing Businesses with a turnover of more than Rs 5 crore have to generate e-invoices under GST regulations. This document is applicable to certain supplies, which include Business-to-Business (B2B) transactions, supplies made to Special Economic Zones (with or without payment), exports (with or without payment), and deemed exports.
And with certain supplies where e-invoicing is not applicable, which include SEZ units, insurers, banking and financial institutions (including NBFCs), Goods Transport Agencies (GTA) supplying road transport services, passenger transport service providers, cinematograph exhibitors in multiplexes, persons registered under Rule 14 of CGST for OIDAR services , and government departments or local authorities.
Process of e-invoicing 1. Document Creation The documents covered under the e-invoice are invoices, credit notes and debit notes, which are issued by notified taxpayers to registered persons or for exports. Invoice details must be sent to IRP in JSON format
2. Invoice Creation Taxpayers continue to create their invoices on their own Accounting/Billing/ERP Systems (not on a government portal).
3. IRP Reporting Created invoice is reported to the Invoice Registration Portal(IRP)
4. IRN Generation On reporting, the IRP generates a unique Invoice Reference Number (IRN), digitally signs it, and returns the e-invoice. A GST invoice is valid only with this IRN.
5. QR code Creation The system also generates a QR code containing the IRN and other key details, which can be printed on the invoice for offline verification.
6. Successful Reporting Upon successful reporting, the supplier receives a digitally signed JSON that includes the QR code.
7. Readable / Printed e-invoice This JSON can be converted into a readable PDF or printed as a paper invoice with the entity’s logo and other information. Both printed and PDF always carry the QR code.
Understanding elements of the e-Invoice System 1. Unique Invoice Reference Number (IRN) It is created using a hash, which combines the GSTIN of the document generator (invoice, credit note, or debit note) financial year, the document type, and the document number, such as the invoice number to be published in the e-invoice standard, and it ensures that every invoice is unique and no duplicate exists. To ensure no duplication, the registrar checks the hash with the Central Registry of the GST System. If the same IRN already exists, then it gets rejected; only the unique and new invoices are accepted.
2. Digital Signing of e-Invoice by the Invoice Registration Portal (IRP) After uploading invoice details on the IRP, ie, registered portal, the system generates the IRN and digitally signs the e-invoice using its private key. This makes the e-invoice valid for the document generator business. The IRP also sends the signed invoice to both the GST system and the E-Way Bill system.
3. QR code with key details The IRP generates a QR code containing a unique IRN (hash), important invoice details, and its digital signature. The QR code helps in quick verification even without the internet, for example, during a road check by officers. The QR code includes details like GSTIN of the supplier as well as the recipient, invoice number, date of generation, invoice value (taxable and gross tax), number of line items, HSN code of the main item and the unique IRN. Any tampering will make the e-invoice invalid as the digital signature will fail. A mobile app for tax officers/buyers and GST/E-Way Bill systems can be used to verify it. The work of IRP itself is not to store invoices; it only registers, verifies, and generates IRNs and QR codes.
4. Multiple Registrars/IRPs To ensure smooth 24-hour operations, multiple registrars will be introduced. Initially, the National Infographic Centre( NIC ) will serve as the first registrar, with additional IRPs added
5. Standardisation of e-invoice The GST council has set up a technical team that has developed an e-invoice standard after industry consultation. The template has since been notified as Form GST-INV-1.
Check out this template/schema provided on Form GST-INV-1 .
6. Multiple modes for reporting Taxpayers can report the e-invoice through various modes like APIs, mobile apps, offline tools or GSPs. With APIs, ERP/accounting software can directly connect to IRP to upload invoice data and get back the signed e-invoice with IRN. APIs can allow bulk uploads just like the e-way bill system.
7. Printing of e-invoice Once the supplier receives the signed JSON from the IRP, it can be converted into a readable format and printed. The printed e-invoice includes company details, logo, even though reporting can be done electronically supplier can use a physical form which paper format
8. Cancellation of e-invoice A seller can cancel an IRN if required, but only within a fixed time after generation. This is done using the “Cancel IRN” API on the e-invoice portal. After cancellation, the same invoice number cannot be used again in the future.
9. Amendment of e-invoice Any modification to the e-invoice already uploaded must be made on the GST portal. If a changed e-invoice is resubmitted to the IRP, it will be rejected since the IRN (hash) is already recorded in the IRP system; therefore, amendments cannot be processed through the IRP system.
Other similar instruments of GST E-Way Bill It is for enrolled/ GST registered transporters to create a waybill (document to be carried by the person in charge of conveyance) for the movement of goods valued more than Rs 50,000, and it must be created before the dispatch for reasons not than supply or due to incoming supply from a non-registered person. It has streamlined the movement of goods by eliminating old state border checks with an online centralised system. This system keeps details of everything from date, value of goods, transport details, reason of transportation, HSN code, Vehicle number for road transportation, and place of delivery in this bill, making every detail open to view and keeping companies GST compliant.
