E-invoicing is the electronic generation and authentication of invoices using a standardised format compatible with any software. Its implementation under GST applies to businesses surpassing a specified annual aggregate turnover. The primary goal of e-invoicing is to enhance the efficiency and transparency of invoicing processes while alleviating the compliance burden for taxpayers.

This blog post explores the E-invoice integration for services and underscores digital invoicing benefits for service providers. Additionally, it addresses frequently asked questions and challenges associated with e-invoicing. Continue reading to gain insights into this transformative invoicing approach.

E-invoicing under GST

An electronic or e-invoice is a digital confirmation validating a financial transaction between a purchaser and a supplier, officially approved by a government tax portal. The concept of e-invoicing involves the digital preparation of business-to-business (B2B) invoices formatted and authenticated by the Goods and Services Tax Network (GSTN). This system ensures businesses follow a uniform format when reporting their invoices to GST authorities.

In August 2019, the government released a draft of the e-invoice for public review. Subsequently, the GST Council modified the draft to align it with regulatory requirements. The standardised e-invoice format facilitates compliance and enhances transparency within the GST ecosystem, encompassing various industries.

Importance of E-invoicing

Before the implementation of e-invoicing, businesses created invoices using multiple software, and the details of these invoices were manually uploaded in the GSTR-1 return or through ERP systems.

Upon the filing of GSTR-1 by the respective suppliers, the invoice information would be reflected in GSTR-2B for the recipients. Simultaneously, consignors or transporters had to generate e-way bills manually, importing the invoices in Excel or JSON format or via ERP.

With the introduction of the e-invoicing system, the process of generating and uploading invoice details remains unchanged. This is achieved by directly importing the Excel tool/JSON or API integration or through a GST Suvidha Provider (GSP). This streamlined data flow applies not only to GSTR-1 preparation but also to e-way bill generation. The e-invoicing system emerges as a pivotal tool in facilitating these processes.

Additionally, E-voice integration with services further enhances the efficiency and accuracy of the invoicing system, extending its benefits across a broader spectrum of business transactions.

Documents necessary for E-Invoicing

  • Invoices issued by the supplier
  • Credit notes issued by the supplier
  • Debit notes issued by the recipient
  • Any other document specified under the Goods & Service Tax Act requiring reporting as an E-Invoice by the document creator

Steps to get an Invoice under GST 

  • Generate a regular invoice on the software: Provide necessary details such as billing name and address, supplier’s GST number, transaction value, item rate, applicable GST rate, tax amount, etc.
  • Raise the invoice on the ERP or billing software: Upload the invoice details, especially mandatory fields, to the Invoice Registration Portal. This can be done using a JSON file, through an application service provider (such as an app or a GST Suvidha Provider), or directly via API.
  • Generate the Invoice Reference Number (IRN): The Invoice Registration Portal validates key details of the Business-to-Business invoice, checks for duplications, and generates an Invoice Reference Number (IRN) as a unique identifier.
  • Create a QR code in Output JSON: Once the IRN is generated, the Invoice Registration Portal digitally signs the invoice and creates a QR code in Output JSON format. If the supplier has provided their email ID in the invoice, they receive an intimation of the E-Invoice generation via email.
  • Send details to the GST Portal and E-Way Bill Portal: The Invoice Registration Portal sends authenticated invoice details to the GST Portal, auto-filling the seller’s GST Return form (GSTR-1). Additionally, the details are sent to the E-Way Bill Portal for seamless integration with the E-Way Bill generation process.

Taxpayer Categories exempted from generating e-invoices under GST

  • Insurance companies, banking entities, and financial institutions, including NBFCs.
  • Goods Transport Agencies (GTAs).
  • Registered entities providing passenger transportation services.
  • Registered entities providing services related to admission to the exhibition of cinematographic films in multiplex services.
  • SEZ units (excluded via CBIC Notification No. 61/2020 – Central Tax).
  • Government departments and local authorities (excluded via CBIC Notification No. 23/2021 – Central Tax).
