    Basics

    5 practical questions answered in plain English.

    What is e-invoicing under GST?+

    E-invoicing is the process of reporting specified GST invoices, debit notes and credit notes to an Invoice Registration Portal so that an IRN and signed QR code are generated before issuing the invoice.

    Is e-invoicing the same as making invoice in accounting software?+

    No. Your accounting software can create the invoice, but the e-invoice step happens when invoice data is reported to IRP and a valid IRN is generated.

    What is IRN in e-invoicing?+

    IRN means Invoice Reference Number. It is the unique reference generated after the invoice data is successfully registered on the Invoice Registration Portal.

    What is the QR code in e-invoice?+

    The signed QR code is generated by the IRP and contains key invoice details. It helps verify that the invoice is a valid e-invoice.

    Is an invoice valid without IRN where e-invoicing applies?+

    For covered B2B and specified transactions, the invoice should have a valid IRN. Issuing invoice without required IRN can create compliance and ITC problems.

    Applicability

    5 practical questions answered in plain English.

    Who is required to generate e-invoice in India?+

    GST-registered taxpayers crossing the notified aggregate turnover threshold in any preceding financial year from 2017-18 are required to comply, unless specifically exempt.

    What is the current e-invoicing turnover limit?+

    The current notified threshold is ₹5 crore and above from 1 August 2023, subject to applicable exemptions and notifications.

    Is e-invoicing based on GSTIN-wise turnover?+

    No. The threshold is generally checked on PAN-based aggregate turnover across GST registrations.

    If turnover later falls below the limit, can e-invoicing stop?+

    Generally, once e-invoicing becomes applicable based on past aggregate turnover, the taxpayer should continue unless there is a specific exemption or legal change.

    Does e-invoicing apply to small businesses below ₹5 crore?+

    For taxpayers below the notified threshold, e-invoicing is not mandatory at present, though portal enablement or voluntary options may differ.

    🧾

    Transactions Covered

    5 practical questions answered in plain English.

    Does e-invoicing apply to B2B invoices?+

    Yes. B2B invoices are the core category covered under e-invoicing for applicable taxpayers.

    Does e-invoicing apply to exports?+

    Yes. Export invoices are generally covered for applicable taxpayers, including exports with or without payment of tax.

    Does e-invoicing apply to SEZ supplies?+

    Yes. Supplies to SEZ units or developers are generally covered for applicable taxpayers.

    Are debit notes and credit notes covered?+

    Yes. Debit notes and credit notes related to covered supplies generally require IRN generation.

    Does e-invoicing apply to B2C invoices?+

    At present, e-invoicing is mainly for B2B and specified transactions; B2C e-invoicing has been discussed but is not broadly mandated in the same way.

    🚫

    Exemptions

    5 practical questions answered in plain English.

    Are all GST taxpayers above ₹5 crore covered?+

    Not always. Some classes of taxpayers are exempt under Rule 48(4) and related notifications, so exemption should be checked before implementation.

    Are banks and financial institutions exempt?+

    Certain banking, insurance and financial service entities have exemptions under e-invoicing rules, subject to exact legal category.

    Are GTA operators exempt from e-invoicing?+

    Goods Transport Agency services have specific exemption coverage under the rules; applicability should be checked based on registration and activity.

    Are SEZ units exempt?+

    SEZ units have been treated differently under e-invoicing exemptions. Each case should be checked using GSTIN, activity and current notification language.

    Should exempt businesses declare exemption on invoices?+

    If a taxpayer is exempt despite crossing the threshold, invoice declaration and portal status should be managed carefully to avoid customer disputes.

    Process

    5 practical questions answered in plain English.

    How is e-invoice generated?+

    Prepare invoice in your billing system, upload or push data to an IRP, receive signed JSON with IRN and QR code, then issue invoice with required details.

    Can CompanyJi help set up e-invoicing?+

    Yes. CompanyJi can check applicability, map invoice types, configure process, coordinate with software/vendor and guide your accounts team.

    Is DSC required for e-invoice?+

    E-invoice generation is generally portal/API based and does not work like MCA filings. DSC may not be the central requirement, but authorised portal access is important.

    Can e-invoice be generated manually?+

    Yes, small volume businesses may use portal or offline tools, while larger businesses usually prefer API or software integration.

    Can e-invoice be cancelled?+

    Yes, cancellation is possible within the permitted window. After that, correction usually happens through credit note/debit note or GST return adjustment.

    Timeline

    5 practical questions answered in plain English.

    When should e-invoice be generated?+

    It should be generated before issuing the covered invoice to the recipient, so the invoice has a valid IRN and QR code.

    Is there a 30-day reporting limit for e-invoices?+

    From 1 April 2025, taxpayers with AATO of ₹10 crore and above are restricted from reporting e-invoices older than 30 days on IRP.

    Does the 30-day reporting limit apply below ₹10 crore?+

    As per the advisory, the 30-day reporting restriction does not apply to taxpayers with AATO below ₹10 crore as of that advisory.

    How long does e-invoice implementation take?+

    A simple portal-based setup can be done quickly, but ERP/API integration, branch training and testing may take longer.

    Can old invoices be converted into e-invoices later?+

    Delayed reporting is risky and may be blocked for certain taxpayers. It is better to generate IRN in real time or within the permitted reporting window.

    📄

    Documents & Data

    5 practical questions answered in plain English.

    What data is required for e-invoice?+

    GSTIN, legal/trade name, invoice number, date, HSN/SAC, tax values, place of supply, recipient details and item-level details are generally required.

    Is HSN mandatory in e-invoice?+

    HSN/SAC details are important in invoice reporting. The correct code depends on the nature of goods/services and GST rules.

    Is transport detail required in e-invoice?+

    Transport details may be relevant when generating e-way bill along with e-invoice, but invoice reporting can be completed with required invoice data.

    Can one invoice number be reused after e-invoice cancellation?+

    Invoice numbering should remain consistent with GST rules and accounting records. Reuse after cancellation should be handled carefully.

    Can e-way bill be generated from e-invoice data?+

    Yes. E-way bill details can often be generated or linked using e-invoice data where movement of goods requires it.

    ⚠️

    Penalties & Risks

    5 practical questions answered in plain English.

    What happens if e-invoice is not generated when mandatory?+

    The invoice may be treated as non-compliant and can create penalties, customer ITC issues and GST return mismatch.

    Can buyer lose ITC if supplier fails e-invoicing?+

    Buyer ITC may be affected if invoice data, GSTR-1 and e-invoice reporting are not aligned. Customers often demand valid IRN for covered suppliers.

    Can wrong e-invoice be corrected?+

    IRN data cannot be edited after generation. Corrections are generally handled through cancellation within time or credit/debit note and GST return treatment.

    What are common e-invoicing mistakes?+

    Wrong GSTIN, wrong document type, duplicate invoice number, incorrect tax rate, incorrect place of supply and delayed reporting are common mistakes.

    Should e-invoice data match GSTR-1?+

    Yes. E-invoice data flows into GST reporting and should be reconciled with GSTR-1, books and customer records.

    💻

    Software & Support

    5 practical questions answered in plain English.

    Do I need special software for e-invoicing?+

    Not always. Manual/portal tools may work for low volume. Businesses with regular invoicing should use accounting software or API-enabled tools.

    Can Tally or ERP generate e-invoices?+

    Many accounting and ERP systems support e-invoice generation, but configuration, GSTIN credentials and testing are important.

    Can CompanyJi check whether my GSTIN is enabled?+

    Yes. We can help verify enablement status and confirm whether legal applicability actually exists based on turnover and exemptions.

    Can e-invoice be generated for multiple branches?+

    Yes. Businesses with multiple GSTINs need GSTIN-wise setup, credentials and process controls.

    Can CompanyJi train our accounts team?+

    Yes. We can provide practical guidance on invoice flow, cancellation, credit notes, e-way bill linkages and reconciliation.
