GST e-invoicingRaise IRNs on shipping invoices without rekeying.
Turn export and import invoices into GST e-invoices: check the payload, raise the IRN through a GSP, and download the PDF with the signed QR code.

Tax and customs
Overview
Sailix builds the Indian GST e-invoice from an export or import invoice you have already raised. The seller block comes from your organization or branch, the buyer from the customer record, and every charge line takes its SAC code from the tariff item and its GST rate from the tax service group, so the e-invoice repeats what the invoice charged.
Before anything leaves the system, a check run lists every gap in one pass: a missing GSTIN, a charge line without a SAC code, a pincode that is not six digits. Once the payload is clean, Sailix sends it through a GST Suvidha Provider to the Invoice Registration Portal and stores the IRN, acknowledgement number, acknowledgement date and signed QR code.
Capabilities
What it does
Generate from existing invoices
Pick an export or import invoice from the list and Sailix maps its parties, charge lines and round-off to the e-invoice schema. Invoices that already hold an IRN show it.
Check before you send
The Check action builds and validates the payload without contacting the portal, then names each issue and the fix, so a portal rejection is not your first warning.
CGST, SGST or IGST
Sailix compares the seller's state with the place of supply and splits each line into CGST and SGST for an intra-state supply, or IGST for an inter-state one.
GSTIN lookup
Type a GSTIN and Sailix fetches the registered legal name, address, pincode and state code through the GSP, then fills them into the seller or buyer block.
E-invoice PDF with QR
Each generated e-invoice downloads as a PDF showing the IRN, acknowledgement number and date, the signed QR code, both parties, HSN or SAC lines and tax totals.
History and test mode
A history tab lists every e-invoice generated, each with a PDF download. In sandbox mode the screen shows a banner and the PDFs carry a test watermark.
Workflow
How it works
First
Set up the tax masters
Record the GST number on your organization or branch, GST numbers and pincodes on customers, SAC codes on tariff items, and GST values in tax service groups.
Then
Raise the invoice in INR
Create the export or import invoice as usual. The e-invoice is built from local currency amounts, and Sailix refuses to generate one when the local currency is not INR.
Next
Check and correct
Open GST Invoice Generation, run Check on the invoice and fix what it reports. Overrides let you supply a party detail, a place of supply or a default SAC code for that run.
Finally
Generate and download
Click Generate. Sailix sends the payload through the GSP, saves the IRN and signed QR code against the invoice, and offers the PDF on the same row.
Questions
Questions and answers
How does Sailix generate an IRN for a shipping invoice?
- Sailix maps the export or import invoice to the e-invoice schema, validates the totals and the tax split locally, and sends the payload to the Invoice Registration Portal through a GST Suvidha Provider. The IRN, acknowledgement details and signed QR code that come back are stored with the invoice.
What happens if an invoice is missing a GSTIN or a SAC code?
- The Check action reports every problem at once, for example a malformed GSTIN, a missing legal name or address, a pincode that is not six digits, or a charge line with no SAC code. The payload is not sent to the portal until it passes these checks.
Can I generate an e-invoice for an overseas or unregistered buyer?
- Yes. A buyer with no GSTIN is sent as unregistered, and when the place of supply is outside India the payload is marked as an export supply and taxed with IGST. You can set the place of supply state code for a single run from the overrides panel.
Can I cancel an IRN from Sailix?
- Not from the GST Invoice Generation screen today. Sailix generates IRNs, looks up GSTIN details and stores the portal response, and a second request for an invoice that already has an IRN returns the stored record instead of a duplicate. Cancellation is done outside Sailix.
