Invoicing clients in other countries introduces currency, tax, and payment complications. Here's how to handle each one professionally.
The Extra Complexity of Cross-Border Invoicing
Invoicing a domestic client is straightforward. Add up the services, apply your tax rate, include your bank details, send. International invoicing adds several layers: which currency to use, whether to charge local tax, how the payment actually gets transferred, and who pays the fees.
Getting these decisions right — and documenting them on the invoice — prevents disputes and payment delays.
Which Currency to Invoice In?
You have three options:
Your home currency: You always know exactly what you'll receive. The client bears the currency risk. Common when your home currency is strong (USD, EUR, GBP). Simpler for your accounts.
Client's currency: Easier for the client. You bear the currency risk — if their currency falls before you're paid, you receive less in your home currency than you expected.
A neutral currency (USD or EUR): Common in international trade even when neither party is American or European. Both parties accept the benchmark currency risk.
There's no universally right answer. For most small businesses, invoicing in your home currency is simplest. For larger or repeat clients, match their currency if it makes the relationship easier.
State the currency clearly: Write "USD 2,400.00" not just "2,400.00." Ambiguous currency on an invoice causes real problems.
GST/VAT on International Sales
In most countries, services exported to overseas clients are zero-rated or exempt from your local GST/VAT. This means:
However, the rules vary significantly by country, type of service, and whether the client is a business (B2B) or consumer (B2C). EU VAT rules, US sales tax, and Australian GST all have different cross-border provisions.
Get this confirmed by your accountant before issuing international invoices. The penalties for incorrectly charging or not charging consumption tax cross-border are significant.
On the invoice: if zero-rated, note "Exported services — GST/VAT zero-rated" rather than simply leaving the tax section blank.
Payment Methods for International Clients
Bank transfer (SWIFT/IBAN): The standard for international B2B payments. Slow (2–5 days), potentially expensive (fees at both ends). Include your full SWIFT/BIC code and IBAN (or account routing for US clients).
Wise (formerly TransferWise): Lower fees than bank-to-bank SWIFT. You can create multi-currency accounts and receive payments locally in USD, EUR, GBP, AUD. Very popular with freelancers with international clients.
PayPal: Widely available globally. Higher fees (2–4%). Works well for smaller amounts.
Stripe: Accepts cards from clients globally. Fee per transaction. Funds typically settle in your home currency.
Crypto: Occasionally used, especially in tech. Removes bank friction but introduces volatility risk unless you use stablecoins.
For ongoing international client relationships, Wise multi-currency accounts are often the most cost-effective solution.
Who Pays the Transfer Fees?
Bank SWIFT transfers involve fees at both ends. State on your invoice: "Bank transfer fees are the responsibility of the sender. Please ensure the full invoice amount is received."
This is standard practice. If you receive less than invoiced due to bank fees, follow up for the difference or factor it into future pricing.
Currency Risk: Protecting Yourself
If you're invoicing in a foreign currency on Net 30 terms, the exchange rate when you're paid may differ from when you invoiced. To manage this:
Invoice promptly and chase promptly. The shorter the time between invoice and payment, the less exchange rate movement you're exposed to.
Include a clause for significant movements: "In the event of a currency movement exceeding 5% between invoice date and payment date, a revised invoice may be issued."
Use forward contracts (for large amounts): A bank or FX broker can lock in today's exchange rate for a future payment — useful for large contracts.
