What happens in the flow
A business usually creates invoice data in its accounting, billing or ERP system. When e-invoicing applies, the required document data is reported to an authorised IRP. The portal validates key fields, generates an Invoice Reference Number (IRN), digitally signs the payload and provides a QR code. Your own system can then produce the customer-facing invoice.
Do not confuse an e-invoice with an ordinary electronic invoice
A PDF invoice sent by email may be electronic in the everyday sense. GST e-invoicing has a specific compliance meaning. Applicability depends on current notifications and facts about the taxpayer and transaction. Check the official portal and take tax advice instead of using an old turnover threshold from an online post.
Operational controls that matter
- Keep customer GSTIN and item/HSN data accurate before the invoice is created.
- Use a controlled invoice numbering sequence.
- Ensure the accounting and e-invoice data reconcile.
- Train the team on cancellation and correction workflows.
- Retain the evidence and seek advice for exceptions.
