Short answer

E-invoicing is mandatory for a registered business whose aggregate turnover has crossed Rs 5 crore in any financial year from 2017-18 onwards. If your aggregate turnover is Rs 10 crore or more, you must also report each invoice, credit note and debit note to the Invoice Registration Portal within 30 days of its date, from 1 April 2025. The 57th GST Council (8 October 2026) recommended extending e-invoicing to certain reverse charge and import of services supplies for businesses at Rs 5 crore or more, but no start date is notified yet.

Last updated 3 November 2026. Rules, fees and forms change, so confirm the current position on the official portal before you act.

THE OUTCOME YOU ARE BUYING

Complete e-invoicing setup and compliance with the right facts, approvals and evidence.

COMMON MISTAKES

Avoid preventable delays, rework and scope gaps.

These issues commonly surface after a commercial commitment, deadline or authority query has already created time pressure.

Starting without an applicability check

This can select the wrong form, authority or document route.

Using inconsistent source data

Conflicts create queries and correction work.

RISK CONTROL

Small input errors can create larger commercial or compliance consequences.

Review the requirement early, disclose accurate facts and retain a complete approval and completion trail.

Delay exposureLate action may narrow options or add cost.
Rejection or queryIncomplete or inconsistent records can trigger follow-up.

Who has to issue e-invoices

E-invoicing applies to B2B supplies, exports and supplies to SEZs by registered businesses over the turnover limit. Each invoice gets an invoice reference number (IRN) and a QR code from the Invoice Registration Portal, and the data flows to the GST portal. Your accounting or billing software normally connects to the portal through an API.

Some persons are exempt, such as SEZ units, insurers, banks and financial institutions, goods transport agencies, and passenger transport and cinema services. Check the current exemption list on the GST e-invoice portal.

The 30-day reporting limit

For taxpayers with aggregate turnover of Rs 10 crore or more, the portal does not accept a document older than 30 days from its date. A missed invoice cannot be reported later, and your buyer may lose input tax credit on it. Build a weekly check so no invoice or credit note is left out.

What the 57th GST Council recommended (not yet law)

E-invoicing for reverse charge supplies from unregistered persons and for imported services, for taxpayers with turnover of Rs 5 crore or more.
Better matching between GSTR-1 and GSTR-3B, and an invoice management system option to accept, reject or hold invoices before GSTR-2B is generated.
No effective dates are given in the release. Wait for the notification before changing your process.

How to set up e-invoicing

1
Check your turnover
Confirm aggregate turnover across all GSTINs under one PAN against the Rs 5 crore and Rs 10 crore limits.
2
Register on the e-invoice portal
Enable e-invoicing for your GSTIN and create API credentials.
3
Connect your software
Link your billing or ERP software so each invoice gets an IRN and QR code.
4
Test, then go live
Run sample invoices, credit notes and cancellations on the sandbox first.
5
Monitor weekly
Reconcile IRNs against sales and report any gap within 30 days.

Common mistakes to avoid

Counting turnover for one GSTIN only when the limit works on aggregate turnover under the PAN.
Issuing a normal invoice first and trying to report it after 30 days.
Forgetting credit notes and debit notes, which also have to be reported.
Printing the invoice without the IRN and QR code once e-invoicing applies.
Cancelling an e-invoice after the cancellation window and then having to issue a credit note.
