E-Invoice for Export Invoices: Fields and Mistakes

Finin2min GST Desk·June 2026·8 min readEXPORT INVOICE

Export invoices require more discipline than ordinary B2B invoices because GST law, LUT/zero-rated supply treatment, e-invoice schema and foreign customer data must all agree. A small field error can create refund, LUT or GSTR-1 mismatches.

ℹ️

Quick answerAn export e-invoice fails silently when its fields disagree with each other, not just when a number is wrong. The LUT/"with-payment" endorsement, the recipient’s country of destination, and the actual place-of-supply classification all need to point to the SAME conclusion - if your invoice says "under LUT without payment of IGST" but your refund workings assume IGST was paid, the mismatch surfaces later as a refund rejection, not at invoice generation. Freeze these fields before IRN generation, not after.

What Rule 46 requires for export invoices

Rule 46 requires normal tax-invoice particulars and also specific export endorsements. For exports/SEZ supplies, the invoice should carry the relevant endorsement for supply on payment of integrated tax or under bond/LUT without payment of integrated tax, as applicable. It should also include name and address of recipient, delivery address and country of destination.

Export invoice field checklist

Field	Control check	Mistake to avoid
Recipient details	Foreign buyer name/address as per contract and invoice.	Using internal short names only.
Country of destination	Match shipping/service documentation.	Leaving country blank or inconsistent.
LUT/IGST endorsement	Use the correct Rule 46 endorsement.	Mixing “with payment” and “without payment” language.
Place of supply	Verify export-of-service/place-of-supply logic separately.	Assuming all foreign billing is export.
Currency/value	Keep invoice, bank realisation and books reconcilable.	Mismatch between ERP and e-invoice payload.

Worked example

Example: An IT services exporter in Pune raises a ₹12 lakh invoice to a US client, correctly marked "supply under bond/LUT without payment of integrated tax" per Rule 46, with the US client’s registered address and "United States" as country of destination. Three months later, while filing the GST refund application, the finance team discovers the e-invoice payload sent to the IRP listed the client’s billing address (a shared services address in Singapore) instead of the contracting entity’s US address - the country-of-destination field and the actual contract do not agree. The refund officer flags the mismatch, and the exporter must produce the contract, purchase order and correspondence to prove the US entity was the genuine recipient before the refund is released. The invoice was not "wrong" in isolation - its fields simply told two different stories.

Mistakes that affect refunds

Wrong export endorsement on invoice.
Customer location not supported by agreement, purchase order or statement of work.
Mismatch between invoice value in books, IRP data and refund statement.
Treating intermediary-like arrangements as exports without checking the IGST Act definition.
Not reconciling LUT, invoice, GSTR-1 and refund application data.

Control process for finance teams

Create a separate export invoice series if operationally useful.
Freeze export invoice fields before IRN generation.
Verify LUT validity before raising invoices under LUT.
Keep agreement, invoice, FIRCs/BRCs and refund workings in one folder.
Run an export invoice reconciliation before filing refund claims.
