Use Case

Invoice Generator for Export Businesses

Export invoicing has a single expensive decision behind it: with a Letter of Undertaking on file, the supply is zero-rated and you charge no tax. Without one, you must pay IGST and claim it back as a refund — the same end position, several months later.

Recommended workflow

Billing needs for Export Businesses

An LUT reference on the invoice, which is what makes the supply zero-rated without paying tax
Currency and the exchange rate used, since your books are in INR and the invoice is not
IEC code, consignee details and port of loading for the shipping documents
Incoterms, which decide who bears freight and insurance and therefore the invoice value
A proforma for the buyer to open a letter of credit against

Recommended workflow

1File the LUT before the financial year starts. It is an annual filing, it costs nothing, and exporting without one converts every invoice into a refund claim.
2Mark the invoice clearly as a supply meant for export under LUT without payment of integrated tax. The wording is what customs and your own return both key off.
3Record the exchange rate you used and its date. GST valuation uses the rate on the invoice date; your realisation will differ, and that difference is a foreign exchange gain or loss rather than a change to the invoice.
4Issue a proforma first where a letter of credit is involved. The buyer needs a document to open the LC against, and a proforma does this without creating a tax point.
5Match the commercial invoice to the shipping bill exactly. A mismatch in value, quantity or description between the two is what holds up both customs clearance and any refund.

Zero-rated is not the same as exempt

An exempt supply carries no tax and no input credit — the tax you paid on your own purchases is a cost. A zero-rated supply carries no tax and full input credit, so you recover what you paid upstream. Exports are zero-rated, which is considerably better, and the distinction is worth understanding before treating an export like an exempt sale.

The practical consequence is that an exporter usually accumulates credit rather than paying tax, because purchases carry GST and sales do not. That credit is refundable, and the refund route you take — LUT without payment, or pay-and-claim — is decided once a year rather than per invoice.

Incoterms decide what the invoice value is

FOB, CIF and DDP are not shipping jargon on an export invoice — they determine what is included in the price and therefore what the invoice states. A CIF invoice includes freight and insurance in the value; an FOB invoice does not, and the buyer arranges both.

Getting this wrong shows up at customs, where the declared value has to reconcile with the terms, and in your own margin, where quoting CIF and costing FOB silently absorbs the freight. Naming the term on the invoice, with the named port, removes both problems.

Frequently Asked Questions

What is an LUT and do I need one?

A Letter of Undertaking is an annual declaration that lets you export without paying IGST upfront. Without it you must pay the tax and claim a refund afterwards. It is filed on the GST portal, takes minutes, and applies for the financial year — an expired LUT is a common and entirely avoidable reason for a stuck export.

Is export of services zero-rated too?

Yes, where the conditions are met: the supplier is in India, the recipient outside it, the place of supply is outside India, payment is received in convertible foreign exchange, and the two parties are not merely establishments of the same person. That last condition catches Indian subsidiaries billing their own foreign parent.

What is the difference between a proforma and a commercial invoice?

A proforma is a quotation in invoice form — used to open a letter of credit or arrange an import licence, and it creates no tax liability. The commercial invoice is the real document that accompanies the shipment and is what customs, the bank and your GST return all work from.

Which exchange rate applies?

For GST valuation, the rate applicable on the date of the invoice. Your accounting will also record the rate on realisation, and the difference between the two is treated as exchange gain or loss — it does not change the invoice value or the tax position.
