e-Invoice

What this connects

Your GST invoices to the Invoice Registration Portal through a GST Suvidha Provider.

Supported workflows

• Submitting an invoice for IRN generation
• Printing the signed QR code on the invoice
• Cancelling an IRN within the permitted window

Data exchanged

• Invoice header, line items, HSN codes and tax breakup
• Supplier and recipient GSTIN
• IRN, acknowledgement number and signed QR code returned by the portal

Setup requirements

• GST registration meeting the e-Invoice turnover threshold
• A GSP or IRP account with API credentials
• Correct HSN/SAC codes on all product masters

Permissions required

• Authorisation to submit invoices on your GSTIN

Security and privacy

• Data is transmitted over encrypted connections (TLS).
• Credentials and tokens are stored server-side and never exposed to the browser.
• Access can be revoked at any time from the provider's own account settings.

Known limitations

Stated plainly, because finding these out during implementation is worse than knowing them now.

• The IRP allows cancellation only within a limited window after generation.
• Portal downtime is outside our control; failed submissions are queued for retry.
• Invoices with incorrect HSN or tax data are rejected by the portal, not silently accepted.
