Should I invoice a US or EU client in INR or in their currency?

Invoice in the currency the contract names — usually USD, EUR, or GBP. Your bank or processor converts on receipt. Putting INR on a USD SOW creates a forex fight on every invoice.

Do I charge GST on export of services?

Export of services is typically zero-rated when the place of supply is outside India and other GST conditions are met. Many exporters file a LUT so they invoice at 0% GST instead of paying GST and claiming a refund. Confirm with a CA — this is not GST advice.

What tax ID should appear on the invoice?

Your GSTIN if you are registered, plus the client’s name, address, and country. Notwen can print the GSTIN on the PDF. It does not file GSTR returns or push invoices to the IRP.

How to Invoice International Clients from India

The invoice has to survive two accountants

A foreign AP team needs a clean total, currency, and payment path. An Indian CA needs GST treatment that matches an export of services, not a domestic 18% line you invented. One PDF should satisfy both.

This is educational, not tax, FEMA, or GST advice. For the GST invoice fields themselves, see GST invoice for freelancers (export of services).

Currency and the contract

Bill in the contract currency.
State the amount due once, prominently. Do not make AP convert INR in their head.
Name one payment method (wire, Wise, PayPal) with account details under the total.

GST in one paragraph

If the work is an export of services (place of supply outside India, payment in convertible foreign exchange, and the other statutory conditions), you generally do not add 18% GST on the face of the invoice. Exporters often execute a LUT and show GST at 0% with an export / LUT remark. If you are not registered, or the supply is not an export, the answer changes — ask a CA before you copy a template from Twitter.

What belongs on the PDF

Same non-negotiables as how to invoice as a freelancer, plus:

Your GSTIN (if registered)
Client country / address sufficient for place-of-supply
Currency and due date
A one-line GST treatment (e.g. export of services, LUT) when that is what you actually filed

Notwen already supports a labeled GSTIN on invoices. It does not file GST, generate e-invoices on the IRP, or act as a GSP.

Pricing the work before you send

If the rate is still a guess, run the India freelance rate calculator (GST, 44ADA, bench time) before the SOW.

Request early access to send those invoices from the same ledger that tracks what actually landed.
