What IsGST eInvoicing / Invoice Registration?
GST eInvoicing is a system where B2B invoices, credit notes, and debit notes are authenticated electronically by the Invoice Registration Portal (IRP), a government-notified platform, before being issued to buyers. The IRP assigns a unique Invoice Reference Number (IRN) and digital signature to the transaction, and transmits the validated invoice data to GST and e-way bill systems automatically.
This system enhances interoperability, reduces manual data entry, and helps eliminate errors and invoice fraud. Businesses whose turnover crosses the specified threshold must adopt eInvoicing; as of August 2023, the threshold is ₹5 crore for aggregate turnover across all GSTINs under one PAN. At Avibha Legal, we support businesses with eInvoicing onboarding—configuring systems, registering with IRP, generating IRNs, and ensuring compliance with evolving rules and formats.
