GST E-Invoicing Setup & Support
Crossed the e-invoicing turnover threshold? We help you set up IRN and QR-code generation through the IRP, integrate it with your billing, and keep your B2B invoices compliant.
Quick answer
E-invoicing applies where aggregate turnover in any preceding financial year from 2017-18 onwards exceeds ₹5 crore — a threshold set by Notification 10/2023-Central Tax from 1 August 2023. Read that test carefully: it is any preceding year, so scope is a ratchet you cannot fall out of. Rule 48(5) provides that an invoice issued otherwise than in the prescribed manner shall not be treated as an invoice at all.
Applies to: Supplies made on or after 1 August 2023, when the ₹5 crore threshold took effectJurisdiction: India — CGST Act 2017 and CGST Rules 2017Sources checked: 20 August 2026

Overview
What is GST E-Invoicing Setup & Support?
E-invoicing requires certain B2B invoices to be reported to a government Invoice Registration Portal (IRP), which validates them and returns an Invoice Reference Number (IRN) and a QR code. The e-invoice then flows into GST returns and e-way bills.
The scope test is a ratchet, and that is the part most businesses get wrong. Notification 13/2020-Central Tax, as amended, applies Rule 48(4) to registered persons whose aggregate turnover in any preceding financial year from 2017-18 onwards exceeds five crore rupees. The words any preceding financial year from 2017-18 onwards were substituted by Notification 70/2020-Central Tax, and the ₹5 crore figure by Notification 10/2023-Central Tax with effect from 1 August 2023. So a business that crossed ₹5 crore once in, say, FY 2019-20 and has shrunk since is still in scope — you do not fall back out. It covers supplies to a registered person or for exports, which includes tax invoices, credit notes and debit notes.
Some classes are excluded outright, by name in the same notification: a government department, a local authority, a Special Economic Zone unit, and the classes in Rule 54(2), (3), (4) and (4A) — insurers, banking companies and financial institutions including NBFCs; goods transport agencies; suppliers of passenger transportation service; and suppliers of services by way of admission to the exhibition of cinematograph films in multiplex screens. If you are in one of those, turnover does not bring you in.
Rule 48(5) is the sanction, and it lands on your customer as much as on you. It provides that every invoice issued by a person to whom sub-rule (4) applies in any manner other than the manner specified in that sub-rule shall not be treated as an invoice. Not defective — not an invoice. Since section 16(2)(a) requires the recipient to be in possession of a tax invoice before taking input tax credit, a B2B invoice issued without an IRN by someone in scope leaves the buyer with no valid credit document.
We onboard you to the IRP, set up IRN/QR generation that fits your billing, and support you so invoices are compliant and reconciled — we don't claim any private filing arrangement; everything runs through the official IRP. The e-invoice data then feeds your GSTR-1 and your e-way bills.

FAQs
GST E-Invoicing Setup & Support — frequently asked questions
What is GST e-invoicing?
A system where certain B2B invoices are reported to the government's Invoice Registration Portal, which returns an IRN and QR code that make the invoice valid.
Who has to do e-invoicing?
Registered persons whose aggregate turnover in any preceding financial year from 2017-18 onwards exceeds ₹5 crore, for supplies to a registered person or for exports — under Rule 48(4) read with Notification 13/2020-Central Tax as amended, the ₹5 crore figure having been substituted by Notification 10/2023-Central Tax with effect from 1 August 2023. Excluded by name: a government department, a local authority, an SEZ unit, and the Rule 54(2)/(3)/(4)/(4A) classes — insurers, banking companies and financial institutions including NBFCs, goods transport agencies, passenger transport suppliers, and multiplex cinema-admission suppliers. We confirm your exact position, including the year you first crossed.
My turnover has fallen below ₹5 crore. Am I out of e-invoicing now?
No. This is the single most consequential misreading of the notification. The test is turnover in any preceding financial year from 2017-18 onwards — wording substituted by Notification 70/2020-Central Tax — not turnover in the immediately preceding year. Cross the threshold once and you remain in scope permanently, regardless of what happens afterwards. There is no exit mechanism in the notification, only the proviso to Rule 48(4) letting the Commissioner exempt a person or class by a further notification. Businesses that shrink and quietly stop generating IRNs are, on the face of the instrument, issuing documents that Rule 48(5) says are not invoices.
What actually happens if an invoice goes out without an IRN?
Rule 48(5): an invoice issued by a person to whom sub-rule (4) applies, in any manner other than the prescribed one, shall not be treated as an invoice. That is stronger than a defect — the document does not exist as an invoice for GST purposes. The practical consequences run in two directions. Yours: you have made a taxable supply without issuing a valid invoice, with the penalty exposure that carries. Your customer's: section 16(2)(a) requires possession of a tax invoice before input tax credit can be taken, so they have nothing to claim on. In B2B relationships the second usually surfaces first, because your buyer's reconciliation finds it.
What is an IRN?
An Invoice Reference Number — a unique number the IRP assigns to each reported invoice, along with a QR code.
Does e-invoicing replace GST returns?
No. E-invoice data helps populate your returns and e-way bills, but you still file GSTR-1 and GSTR-3B.
What happens if I don't comply once in scope?
A B2B invoice without a valid IRN can be treated as not issued, which can affect your customer's ITC and invite penalties.
Do credit and debit notes need IRNs?
Yes, B2B credit and debit notes within scope also require IRNs.
Can you integrate with my billing software?
We help set up IRN/QR generation to fit common billing setups and your workflow.
Is B2C covered?
Standard e-invoicing applies to B2B/exports; separate dynamic QR rules can apply to large B2C suppliers. We advise based on your case.
How long does setup take?
Onboarding and basic integration typically take a few working days.
