How to Invoice International Clients (Currency, Tax & Getting Paid)

To invoice an international client, agree the billing currency up front, add the buyer's and your own full country addresses plus any tax or registration numbers, decide whether tax applies (cross-border B2B services are often zero-rated or reverse-charged), and include clear international payment details such as your IBAN and SWIFT/BIC. Then send a professional PDF promptly and follow up on time. The rest of this guide unpacks each of those decisions.

Billing a customer in another country is not much harder than billing one down the road — but a handful of new questions appear that you never had to think about for domestic work. Which currency? Do you add VAT or sales tax? What extra details does the invoice need so it clears the client's accounts payable team and their bank? And how do you actually receive the money without losing a chunk to fees? Get these right once and every future overseas invoice becomes routine.

Which currency should you invoice in?

The single most important early decision is the currency. There is no law that forces a particular choice for most service work — it is a commercial agreement between you and the client — but the choice affects who carries the exchange-rate risk and how easy you are to pay. You generally have three options:

• Your home currency. Simplest for your bookkeeping: every invoice and every payment lands in the same currency, so your totals always match. The downside is that the client carries the conversion and may see a different amount leave their account depending on the rate that day.
• The client's currency. Often the friendliest choice for winning and keeping the work, because the client sees a clean, familiar number and knows exactly what they are paying. You then carry the exchange-rate risk between issuing the invoice and the money landing.
• A stable common currency. When neither side's currency is convenient, many cross-border deals settle in a widely traded one such as USD or EUR. It is predictable, easy to convert, and familiar to most accounts teams around the world.

Whatever you pick, state the currency explicitly on the invoice — both the code (USD, EUR, GBP) and, ideally, the symbol. "$1,200" is ambiguous because the dollar sign is used by many countries; "1,200 USD" is not. Our free invoice generator supports 160+ currencies and prints the code on every line so there is no confusion at the other end.

Decide the currency before you decide the price. The number you quote only means something once both sides know which currency it is in — and who absorbs the swing between today's rate and the day you get paid.

Exchange rates and who bears the risk

Whenever an invoice is in one currency and you bank in another, an exchange rate sits in the middle — and rates move. If you invoice in the client's currency and the rate shifts against you before they pay, you receive less than you expected once it is converted. Invoice in your own currency and the risk flips to the client instead. A few practical ways to handle it:

• Build in a small buffer. If you price in a foreign currency, a modest margin can absorb normal rate movement so you are not squeezed on every job.
• Invoice and get paid quickly. The longer money is outstanding, the more the rate can drift. Short, clear payment terms reduce your exposure.
• Note the rate basis for long projects. For multi-month work, you can agree in writing which exchange rate or rate source applies, so a later swing does not turn into a dispute.
• Use an account that converts well. The rate your bank or payment provider gives you matters as much as the headline market rate — more on that below.

You do not need to hedge currencies like a corporation. For most freelancers and small businesses, picking a sensible currency, adding a little buffer, and getting paid promptly is enough to keep exchange-rate surprises small.

Do you charge VAT, GST, or sales tax?

This is the question that worries people most, and the honest answer is: it depends on the rules in both countries, on whether the sale is goods or services, and on whether your client is a business or a consumer. What follows is general orientation, not tax advice — always confirm your own position with a qualified adviser or your local tax authority, because the rules are detailed and change.

A few broad patterns that come up repeatedly for cross-border services:

• Reverse charge (common in the EU and UK for B2B services). When you sell services to a VAT-registered business in another country, you often do not add your own VAT. Instead the customer accounts for the tax in their country under the "reverse charge" mechanism, and your invoice carries a note saying so. The supply still has to be recorded correctly on both sides.
• Zero-rating / out of scope. Many exports of services (and goods) to customers abroad are zero-rated or fall outside your domestic sales tax entirely — meaning you charge no tax but the sale still appears on your returns. The exact treatment depends on your country's rules and where the customer belongs.
• Consumer (B2C) sales can differ. Selling to private individuals abroad, or selling digital products and services, sometimes triggers an obligation to charge the tax of the customer's country once you pass certain thresholds. These thresholds and rules vary widely and are scoped to specific regimes.

As a rough country-scoped illustration: in the UK and EU, B2B services to a business in another member state or third country frequently use the reverse charge, so the supplier shows no VAT and the buyer self-accounts. In the US, there is no national VAT — sales tax is set state by state, and most pure services are not taxed the way goods are, though the picture varies by state and by what you sell. Treat both of these as starting points to check, not as rulings for your situation.

If you need to add or strip a tax amount cleanly on an invoice once you know the correct rate, our VAT and sales tax calculator handles the arithmetic for you. For a deeper look at the document itself and when a fully tax-compliant version is required, see our guide to what a tax invoice is.

The reverse charge does not make tax disappear — it moves the responsibility for it from you to your client. Showing the right note on the invoice is what keeps both sides compliant.

One more boundary worth flagging: if you are shipping physical goods across a border rather than delivering services, a separate customs document comes into play. The currency and tax principles here still apply, but the paperwork that clears the parcel is a commercial invoice, which carries HS codes, country of origin, and Incoterms for customs. This article focuses on the billing side; that guide covers the goods side.

What to include on an international invoice

An international invoice is a normal invoice with a few extra fields that matter once a border and a foreign bank are involved. A complete one typically includes:

1. Your full business details — legal name, full address including country, and contact information. Don't assume the client knows which country you are in.
2. The client's full details — their legal name and complete address with country, plus a contact and any internal reference or purchase-order number they ask you to quote.
3. Tax / registration numbers — your VAT, GST, or business registration number, and the client's number where the relevant regime needs it (for example, for an EU reverse-charge supply).
4. A unique invoice number and the issue date. A consistent sequence keeps your records clean and helps the client's accounts payable match the payment.
5. A clear description of the work or goods — itemised lines with quantities and unit prices, so an approver in another country can see exactly what they are paying for.
6. The currency, shown explicitly — the code on the totals (and ideally each line), so there is zero ambiguity about which "dollar" or "krone" you mean.
7. Any tax line or reverse-charge note — either the tax charged, or a short statement explaining why no tax is added (such as the reverse charge applying).
8. The total due and the payment terms — net days, due date, and any late-payment policy.
9. International payment details — the part domestic invoices skip. Include your IBAN and SWIFT/BIC, the account name and the bank's country, or the receiving details for whichever transfer service you use. Missing or partial bank details are one of the most common reasons an overseas payment stalls.

Spell out the bank details rather than abbreviating. A client in another country may need the SWIFT/BIC, the IBAN, the full bank name and address, and sometimes an intermediary bank to push the payment through. The more complete the invoice, the fewer back-and-forth emails before you get paid.

Worked example: invoicing a client abroad

Suppose you are a freelance designer in Spain billing a software company in the United States for a month of work. A simplified international invoice might read:

• From: Marta Ruiz Design, Valencia, Spain (with VAT number).
• To: Northpoint Software Inc., Austin, Texas, United States.
• Invoice no. / date: 2026-038 / 23 June 2026.
• Description: UI design retainer, June 2026 — 40 hours.
• Amount: 4,000 USD (currency agreed up front, shown on the line and the total).
• Tax: No VAT charged — service supplied to a business outside the EU; note added to that effect.
• Payment terms: Net 14, due 7 July 2026.
• Pay by: IBAN and SWIFT/BIC for a EUR or USD receiving account, with the account name and bank country.

Notice the decisions baked in: the currency was settled before the price, so "4,000" is never ambiguous; the tax treatment is stated rather than left blank; and the payment block is complete enough for a US accounts team to send funds without asking a single follow-up question. Marta carries a little exchange-rate risk because she banks in euros and invoices in dollars, which she has accepted in exchange for being easy for US clients to pay. The exact tax treatment here is illustrative — the right answer for your own work depends on where you and your client belong.

How to get paid by international clients

The fastest invoice in the world still has to convert into money in your account. Cross-border payments can be slow and fee-heavy if you let the default route happen, so it pays to choose the method deliberately and put the details right on the invoice:

• International bank transfer (IBAN / SWIFT). Universally accepted and good for larger sums, but traditional bank wires can carry flat fees on both ends and a marked-up exchange rate. Make sure the client knows whether they or you cover the transfer charges.
• Multi-currency / money-transfer accounts. Services built for cross-border payments often give you local receiving details in several currencies and convert closer to the real market rate, which can be noticeably cheaper than a standard wire. The client pays as if sending domestically, and you hold or convert the currency on your side.
• Online payment platforms. Card and wallet-based processors are quick to set up and convenient for clients, but their percentage fees and currency conversion can add up on larger invoices, so weigh the speed against the cost.

Whichever you choose, the rule is the same: make the currency and the receiving details unambiguous on the invoice itself. Half-filled bank fields, a missing SWIFT code, or an unstated currency are what turn a 2-day payment into a 2-week chase. A few habits that get overseas invoices paid faster:

• Invoice promptly — the clock only starts once the client has the document, and time zones already add a day of lag.
• Set clear, written payment terms with an explicit due date, not just "on receipt".
• Send a polite reminder a few days before and after the due date; international approvals can pass through more hands.
• Consider a late-payment clause. Many businesses add interest or a flat late fee — commonly a small monthly percentage — but what you can charge varies by country and contract, so set it in the agreement, not as a surprise.

A simple checklist before you send

Before any international invoice leaves your outbox, run through this quick list:

1. Currency agreed and shown explicitly (code, not just a symbol).
2. Your and the client's full addresses, both with country.
3. Tax handled correctly — charged, zero-rated, or a reverse-charge note — with registration numbers as needed.
4. Complete international payment details (IBAN, SWIFT/BIC, account name).
5. Clear description, unique invoice number, and a firm due date.
6. A PDF copy kept for your records.

On that last point: keep every invoice you issue. Tax authorities generally expect businesses to retain accounting records for a number of years — often somewhere in the range of five to seven — though the exact period depends on your country, so treat your sent invoices as permanent paperwork.

Frequently Asked Questions

What currency should I invoice an international client in?

Bill in the currency you agreed — often the client's currency or a stable common one such as USD or EUR. State the currency clearly on the invoice and decide in advance who bears the exchange-rate risk.

Do I charge VAT or sales tax to overseas clients?

It depends on both countries' rules. Cross-border B2B services are often zero-rated or handled under a reverse charge where the client accounts for the tax. This is general information, not tax advice — confirm your own position with a qualified adviser. Our VAT and sales tax calculator can do the maths once you know the correct rate.

What should an international invoice include?

All the standard invoice fields plus the billing currency, your and the client's full addresses including country, any tax or registration numbers either side requires, and clear international payment details such as IBAN and SWIFT/BIC.

How do I get paid by an international client?

Offer low-fee cross-border methods such as bank transfer (IBAN/SWIFT) or a money-transfer service, and make the currency and full bank details unambiguous on the invoice so the payment is not delayed or short-paid.
