The implementation of e-Invoicing under the Goods and Services Tax (GST) regime in India has streamlined the invoicing process, making it more efficient and transparent. However, with this new system comes a host of terms and concepts that taxpayers need to understand. This blog post aims to provide a comprehensive glossary of key terms related to e-Invoicing under GST.
1. e-Invoicing
e-Invoicing refers to the process of reporting details of specified GST documents to a Government-notified portal, known as the Invoice Registration Portal (IRP), and obtaining an Invoice Reference Number (IRN). It is important to note that e-Invoicing does not mean the generation of invoices by a Government portal.
2. IRP (Invoice Registration Portal)
The Invoice Registration Portal (IRP) is a government-approved platform where notified persons upload or report invoices. Currently, six portals are authorized to generate IRNs as per Rule 48(4) of the CGST Rules. Reporting invoices and generating IRNs on these portals is free of charge.
3. IRN (Invoice Reference Number)
The Invoice Reference Number (IRN) is a unique identifier for every invoice reported on an IRP. It is generated based on a hash of the supplier’s GSTIN, the financial year, the document type, and the document number.
4. AATO (Annual Aggregate Turnover)
AATO, or Annual Aggregate Turnover, is calculated based on the PAN of a taxpayer and the information provided in their GSTR-3B returns. It represents the total turnover of the taxpayer during a financial year and is used to determine the applicability of e-Invoice reporting requirements.
5. Enablement
Enablement is the process of registering and enabling a taxpayer for e-Invoicing on the GST portal. This allows them to report e-Invoices on any of the six IRPs. Taxpayers are automatically enabled based on their AATO, but if not, they need to self-enable on the portal.
6. GSTIN (Goods and Services Tax Identification Number)
GSTIN is a unique identification number assigned to each registered taxpayer under the GST system.
7. GSTR-1
GSTR-1 is a monthly or quarterly return that taxpayers need to file, containing details of outward supplies, including e-Invoice data.
8. Debit Note
A debit note is a document issued by a seller to notify the buyer of an increase in the quantity and/or value/taxes of a previously issued invoice. It is used to adjust for errors, sales returns, or similar circumstances.
9. Credit Note
A credit note is issued by a seller to inform the buyer about a reduction in the quantity and/or value/taxes of a previously issued invoice. This reduction can occur due to discounts, rebates, or overpayments.
10. e-Invoice QR Code
An e-Invoice QR Code is a two-dimensional barcode that provides information about the invoice. It includes parameters such as the supplier’s GSTIN, the recipient’s GSTIN, invoice number, date of generation, invoice value, IRN, etc.
11. GSTN e-Services App
The GSTN e-Services App is a mobile application designed to enhance the verification process for B2B e-Invoices. It allows users to verify e-Invoices by scanning the QR code, providing key details of the invoice and the live status of the IRN.
12. e-Invoice FO (Front Office) Portal
The e-Invoice FO Portal is the official web portal provided by GSTN where taxpayers can access various e-Invoice-related functionalities, including enablement status, e-Invoice generation, and searching for IRNs.
13. JSON Format
JSON (JavaScript Object Notation) is a standard data interchange format. For e-Invoicing, the invoice data must be uploaded in a predefined schema (INV-01) in JSON format.
14. API for e-Invoice Reporting
IRPs offer API-based functionality for reporting e-Invoices. An API (Application Programming Interface) is a set of protocols for building and integrating software applications.
15. B2B Invoices
B2B invoices are issued in business-to-business transactions. e-Invoicing requirements in India currently apply to B2B invoices for certain taxpayers based on their annual turnover.
16. ERP System
An Enterprise Resource Planning (ERP) system is a type of software used by companies to manage their day-to-day business activities. Taxpayers can continue to generate invoices from their current ERP system, but details of all such B2B invoices need to be uploaded or reported on an IRP in a notified format.
17. OTP (One-Time Password)
An OTP is a password valid for only one login session or transaction. During the registration process on an IRP, an OTP is sent to the registered mobile number for verification.
18. Auto-population
Auto-population refers to the automatic filling in of data in a field. In the context of e-Invoicing, once an e-Invoice has been validated and has received an IRN, the data from the e-Invoice is auto-populated into the supplier’s GSTR-1 form in the GST system.
19. e-Invoice Schema (INV-1 – Version 1.1)
The e-Invoice schema is a predefined and standardized framework that defines the structure of the e-Invoice, including mandatory and optional fields, their format, and rules for the generation of an e-Invoice.
20. Master Codes
Master codes refer to a set of pre-defined codes used in the e-Invoicing system, such as HSN codes, country codes, currency codes, state codes, and others.
21. Signed e-Invoice
A signed e-Invoice is an e-Invoice that has been digitally signed by the Invoice Registration Portal (IRP) after validation. The signed e-Invoice is provided with a unique IRN and QR code.
Conclusion
Understanding these terms is crucial for businesses to comply with the e-Invoicing requirements under GST. As the system evolves, staying updated with the latest changes and guidelines will help ensure smooth and efficient compliance.
