Working with clients in other countries opens up a bigger market, but it adds a few invoicing decisions you do not face at home: which currency to bill in, who absorbs transfer fees, whether tax applies, and how to format dates and numbers so nothing is misread. None of it is complicated once you have a system. This guide covers each decision in plain terms.
Choose the currency before you start
Decide the invoice currency when you agree on the price, not when you send the invoice. You have three main options.
| Option | Pros | Cons |
|---|---|---|
| Bill in your currency (e.g. USD) | Predictable income; no exchange risk for you | Client carries the exchange risk and may find it less convenient |
| Bill in the client's currency | Easier for the client to approve and pay | Your income moves with exchange rates |
| Bill in a major third currency (e.g. USD or EUR) | Common ground for both sides | Both may pay conversion costs |
Whichever you choose, put the currency code next to every amount. A dollar sign alone is ambiguous: USD, CAD, AUD and several other currencies use it. Write "$2,500.00 USD" or "USD 2,500.00", and state the currency in your contract too.
Handle exchange rates and transfer fees
Exchange rates
If you bill in a foreign currency, the amount you receive in your own currency will depend on the rate on the day the money converts. For long projects, consider agreeing a fixed rate, reviewing prices every few months, or billing in your own currency to take the risk off the table.
For your own records, many tax authorities expect foreign income to be converted at a specific rate, such as the rate on the invoice or payment date. Check what your local rules require and keep a note of the rate you used.
Who pays the fees
International payments often lose money along the way: sending fees, receiving fees, intermediary bank charges and currency conversion margins. Decide in advance who covers them and say so on the invoice.
All amounts are in USD. Please ensure the full invoiced amount is received; any bank or transfer fees are to be paid by the sender.
Payment methods for international clients
Choose methods that are easy for the client and affordable for you. Offering two options is usually enough.
| Method | Good for | Things to know |
|---|---|---|
| International wire (SWIFT) | Larger invoices, corporate clients | Fees on both ends are common; intermediary banks may deduct charges; can take a few days |
| Wise or similar transfer services | Freelancers and small businesses | Often lower conversion costs; local account details can let clients pay like a domestic transfer |
| PayPal | Quick payments, smaller amounts | Convenient and widely used, but fees and currency conversion can add up on larger invoices |
| Card payment link | Clients who prefer cards | Processing fees apply; check cross-border card fees |
| SEPA transfer | Clients in the eurozone | Usually low cost for euro payments |
Fees and features change, so compare current pricing before choosing. Whatever you pick, put full payment details on the invoice: account name, bank name, account number or IBAN, SWIFT/BIC code, and your address if the bank requires it.
VAT, GST and the reverse charge (the basics)
Cross-border tax rules are where it pays to be careful. This is a general overview, not tax advice, and rules differ by country and by type of service.
- If you are US-based and selling services to clients abroad, you may not need to charge US sales tax on those services, but the client's country may have its own rules. Check with an advisor if you sell into countries with VAT or GST.
- Reverse charge: In the EU, UK and some other places, many business-to-business services supplied across borders fall under a reverse charge. In simple terms, the supplier does not charge VAT, and the business customer accounts for it in their own country. Invoices often need a note such as "Reverse charge: VAT to be accounted for by the recipient."
- Business vs consumer clients: Reverse charge typically applies to B2B. Selling services to private individuals abroad can trigger different rules, sometimes requiring registration in the customer's country.
- Registration thresholds: Whether you need to register for VAT or GST depends on your location, your turnover and where your customers are. Thresholds vary widely.
If you regularly bill clients in VAT or GST countries, a one-time conversation with an accountant who knows cross-border services is well worth it.
Include the right tax IDs and business details
International clients, especially larger companies, often reject invoices that lack the details their accounting team needs. Include:
- Your full legal name or business name and address
- Your tax ID where relevant (for example a VAT number if you are registered)
- The client's full legal company name and address
- The client's VAT or tax ID, particularly when reverse charge applies
- A purchase order number if the client uses one
- A unique invoice number and clear due date

Format dates, numbers and language clearly
Small formatting choices prevent big misunderstandings.
- Dates: 03/04/2026 means March 4 in the US and April 3 in much of the world. Write dates out, like "October 2, 2026", or use the 2026-10-02 format.
- Numbers: Some countries use a comma as the decimal separator. Including the currency code and two decimal places reduces confusion.
- Language: English is usually fine for international business, but if your client's finance team works in another language, a short bilingual line for key terms can speed approval.
- Payment terms: Spell them out with a calendar date rather than relying on codes. See payment terms explained.
Our free invoice generator lets you set the currency and add tax notes, and the translation invoice template is a good example of a layout built for cross-border clients.
A quick checklist before you send
- Currency code shown next to every amount.
- Who pays transfer fees is stated.
- Full payment details for your chosen methods are included.
- Tax treatment and any reverse charge note are correct for this client.
- Both parties' tax IDs are included where needed.
- Dates are written unambiguously.
Frequently asked questions
Which currency should I invoice international clients in?
Many freelancers bill in their own currency to avoid exchange-rate risk, while others bill in the client's currency to make paying easier. Either works if you agree on it upfront and show the currency code next to every amount. For long projects, consider how rate changes could affect your income.
Do I charge VAT to a client in another country?
It depends on where you and the client are based, whether the client is a business, and what you sell. For many cross-border B2B services in the EU and UK, a reverse charge applies and the supplier does not charge VAT. Check with an accountant for your specific situation.
What is the cheapest way to get paid by international clients?
It varies by country, currency and amount. Transfer services like Wise are often cheaper than traditional wires for smaller amounts, while PayPal is convenient but can be costly on larger invoices. Compare current fees for your typical invoice size.
What does reverse charge mean on an invoice?
Reverse charge means the business customer, rather than the supplier, accounts for VAT in their own country. The supplier issues the invoice without VAT and adds a note explaining that the reverse charge applies. Rules and required wording vary, so confirm them for your situation.
