How to Invoice International Clients from India (2026 Guide)

More Indian freelancers and agencies are earning in dollars, pounds and euros than ever. But invoicing an overseas client isn't the same as billing a domestic one — GST treatment, currency and documentation all differ. Here's how to do it cleanly in 2026.

Is it an "export of services"?

When you provide services to a client located outside India and receive payment in convertible foreign exchange, it generally qualifies as an export of services under GST — treated as a zero-rated supply. That means you typically don't charge GST on the invoice, provided the conditions are met.

LUT vs paying IGST

• Export under LUT (Letter of Undertaking): file an LUT on the GST portal and export without paying IGST — the simplest route for most service exporters.
• Export with IGST: pay IGST on the invoice and claim a refund later. More paperwork.

Most freelancers file an LUT once a year and invoice without GST. Always confirm your specific situation with a CA.

What to put on an international invoice

• Your business name, address and GSTIN
• The client's overseas name and address
• A clear note like "Supply meant for export of services under LUT — GST not charged" (if applicable)
• Currency of billing (USD, EUR, GBP, etc.) and the amount
• Description of services and your bank/SWIFT details for payment

Currency and getting paid

Bill in your client's currency so there's no confusion, and be clear about who bears transfer fees. A multi-currency invoice generator lets you issue invoices in USD, EUR, GBP and more with the right currency symbol — far cleaner than editing a rupee template by hand (see why templates fall short).

Keep your paperwork tight

For export of services you'll want the invoice, proof of foreign inward remittance (FIRC/FIRA), and your LUT reference. Keeping every invoice numbered and stored in one place makes year-end and any GST scrutiny painless. Official guidance lives on the GST portal.
