Invoices above the turnover threshold are registered with the IRP, which returns an IRN and a QR code.
The facts
| Format | GST e-invoice (Schema INV-01) |
| Goes to | Invoice Registration Portal (IRP) |
| Regime | Clearance — the authority authorises the document before it is valid |
| Invoice number | Stays ours: gap-free, sequential, yours to control |
| Seller tax ID | GSTIN |
| Buyer tax ID | GSTIN |
| Peppol EAS code | Not in the official EAS list |
| Integration | ClearTax (Clear) |
The part that costs a day
The IRN and the signed QR code must appear on the printed invoice. A PDF that looks right but carries no QR is not compliant, which is why the template has to be built after registration, not before.
We issue gap-free, sequential numbers that reset on your schedule and are never reused — including for voided documents, which keep theirs. The authority takes the document as numbered.
Never extracted from the gross. The two formulas differ by a cent and the wrong one gets the file rejected. The leftover cent is declared as payment rounding (BT-114), where the standard puts it.
Straight talk
We do not hold your signing certificate, we do not file your periodic returns, and we are not your accountant.
Issuing here goes through ClearTax (Clear), with your own credentials. We build the document, validate it, send it and record what comes back.
