Billing International Clients: Currency, Tax & Payment
International clients can be your most profitable work — or your most complicated. Currency choice, cross-border tax rules, and payment logistics all need decisions upfront. Get them right and billing abroad is routine; get them wrong and it eats your margin.
Currency: Yours or Theirs
Invoicing in your home currency keeps exchange-rate risk with the client and your bookkeeping simple — the default choice for most freelancers. Invoicing in the client's currency can win larger contracts where the buyer needs budget certainty, but then you carry the FX risk between invoice and payment.
Whichever you choose, state the ISO currency code on every amount (USD, EUR, GBP — never a bare '$'). If you quote in one currency and invoice in another, document the conversion rate and its source to prevent disputes.
Tax on Cross-Border Services
Cross-border services often have special tax treatment: EU B2B sales typically use reverse charge (you invoice without VAT and state that reverse charge applies, after validating the client's VAT number via VIES); Australian GST generally does not apply to exports; and US sales tax on services depends on the state and often does not apply to remote services at all.
The rules hinge on where the client is, whether they are a business or consumer, and what you are selling. For significant international revenue, a one-time consultation with a cross-border tax adviser pays for itself — getting this wrong means either overcharging clients or underpaying tax.
Getting Paid Across Borders
International bank wires are slow and fee-heavy; for most small businesses, multi-currency accounts or specialist transfer services deliver faster and cheaper. Offer the payment methods your international clients prefer — in some regions that means local bank transfer options rather than cards.
Clarify who pays transfer fees in your terms: 'bank charges in your country are the client's responsibility' prevents the classic short-payment where fees are deducted from your invoice amount. And invoice promptly — cross-border payments already take longer, so do not add your own delay.
Contracts and Practical Details
Put the governing law, payment terms, late-payment consequences, and currency in a written agreement before starting — chasing a foreign client without a contract is an uphill battle. Include a clear scope and change-order process, since time zones make informal scope discussions harder.
Practical touches: invoice in the client's business hours' morning so it gets same-day attention, confirm the best contact for accounts payable (not just your project contact), and keep records of all cross-border invoices for the longest retention period among the jurisdictions involved.
Frequently asked questions
Do I charge VAT/GST to overseas clients?
Often not on B2B services — many systems zero-rate exports or use reverse charge — but the exact treatment depends on your country, the client's country, and whether they are a business or consumer. Verify the rule for each trade lane rather than assuming.
How do I avoid losing money on exchange rates?
Invoice in your home currency when possible; when invoicing in foreign currency, use a multi-currency account and convert strategically instead of accepting default bank rates. Price a small FX buffer into large foreign-currency quotes.
What if an international client does not pay?
Prevention beats cure: deposits, milestone billing, and clear contracts. Cross-border debt collection is expensive and slow, so structure international engagements so you are never owed more than you can afford to lose.
