GST · e-Invoice
The invoice you raised is the invoice that goes for registration. HSN was captured at the item, the counterparty was validated at entry — nothing is assembled a second time.
A normal sales voucher — nothing special asked of the person typing it.
GSTIN, HSN and mandatory fields checked before anything is sent.
The invoice goes for IRN generation as recorded.
IRN, acknowledgement number and QR stored against the voucher.
The compliant invoice, with QR, out to the customer.
Within the window, cancelled and tracked — never silently deleted.
Registration is irreversible after the window closes, so it is never automatic.

e-Invoicing fails when the registration data is assembled separately from the accounting entry. Here they are the same record — so an IRN cannot describe an invoice your books do not have.
Turnover thresholds change; the page follows the notification, not the other way round.
