How to Invoice International Clients: Currency, Tax, and Getting Paid

By ProQuote Team · July 6, 2026 · 7 min read

Landing a client in another country is a milestone — until you have to invoice them. Suddenly you're deciding between currencies, wondering whether to charge your local tax, and discovering that a "simple wire transfer" can eat $40 in fees. This guide covers the three decisions that matter: what currency to bill in, how to handle tax, and how to actually receive the money.

Decision 1: Which Currency to Invoice In

The default answer: invoice in the client's currency or in USD/EUR — whichever you agreed when quoting. Invoicing a US client in your local currency forces them to guess the conversion, makes your price look unstable, and slows approval.

Whatever you choose, write the currency code, not just the symbol. "$4,000" is ambiguous across the US, Canada, Australia, and Singapore — "USD 4,000" is not. Set the currency explicitly on the invoice and keep it consistent with the quotation.

Decision 2: What About Tax?

The good news: in most countries, services provided to a client abroad are exports, and exports are usually zero-rated — you don't charge your domestic VAT/GST on them.

On the invoice, show the tax line at 0% or omit it, and add a note such as "Export of services — zero-rated" or "VAT reverse-charged to recipient". For the full background on how the systems differ, see Sales Tax vs VAT vs GST around the world. And as always: rules have exceptions — confirm with a local accountant.

Decision 3: How to Get Paid
