How to Invoice International Clients: Currency and Fees

The golden question: whose currency goes on the invoice?

Bill in your currency when you can; bill in theirs when you must win the deal. Invoicing in your own currency moves exchange-rate risk to the client. Invoicing in theirs (dollars/euros for US/EU clients) removes friction from their approval process - often worth it for larger clients.

Whatever you choose, be explicit: "All amounts in USD." Ambiguity about currency is how a 1,200 invoice becomes a dispute. If you show a conversion for reference, label it with the date and source - our currency converter covers 160+ currencies with daily rates.

What is the cheapest way to get paid from abroad?

Ranked roughly from cheapest to most expensive for typical freelance amounts:

1. Multi-currency fintech accounts - local account details in USD/EUR/GBP; clients pay a "domestic" transfer, you convert near mid-market
2. Direct bank transfer (SWIFT) - fine for large invoices, but $15-50 in fees and intermediary banks can nibble the amount
3. Cards / payment links - convenient, ~3% + FX margin
4. PayPal - ubiquitous but often the most expensive once currency conversion spreads are counted

Two rules: state "all transfer fees are the payer's responsibility" on the invoice, and give the client the easiest expensive option alongside the cheapest one - a paid invoice at 3% beats an unpaid one at 0%.

What must a cross-border invoice include?

Everything a normal invoice has (see how to create a professional invoice), plus:

• Currency stated explicitly on every amount
• Your full legal name/entity and country
• Payment instructions with international details - IBAN/SWIFT or account + routing, exactly as your bank publishes them
• Tax notes where relevant - e.g. EU B2B services often fall under reverse charge ("VAT to be accounted for by the recipient"); many US clients will request a W-8BEN form from foreign freelancers - it's routine, not scary

Exchange-rate timing: small print that matters

If you bill in a foreign currency, decide who owns rate movement between invoice and payment. The pragmatic clause: "Invoice payable in EUR; amounts are fixed in EUR regardless of exchange-rate changes." You absorb conversion on your side - priced into your rate, not renegotiated per invoice.

Time zones and the follow-up rhythm

Late payment chasing works internationally exactly as domestically - the reminder sequence just needs to respect working hours. Better: automate it. BillingOtter sends reminders on schedule on Creator Pro and Team, even while you sleep in a different time zone, and the Team plan adds multi-currency invoicing.
