Multi-Currency Invoicing: How to Bill International Clients
A practical guide to invoicing international clients in their currency without losing money to FX or confusing accounting.
Key takeaway
Quote in the client's currency when possible, use a multi-currency invoice app like QuickBill, and accept payment via providers with predictable FX (Wise, Payoneer, or USD via ACH).
International clients are some of the best clients freelancers ever land — but they introduce currency, FX, and bank-routing decisions that domestic invoicing never required.
Quote in the client's currency, when possible
Quoting in the client's local currency (EUR for European clients, GBP for UK clients) reduces friction and increases close rate. The risk is FX — your effective USD revenue can move 1–5% between invoice and payment.
Use a multi-currency invoice app
QuickBill supports USD, EUR, GBP, CAD, and AUD with proper currency formatting on PDFs. You can have one client in EUR and another in USD without any setting changes — currency is set per invoice.
Pick payment methods that survive FX
- Wise (formerly TransferWise) for predictable mid-market FX.
- Payoneer for marketplace and contractor flows.
- USD ACH transfers if your client can pay in USD even from abroad.
- Stripe / card payments — convenient, but watch for 1–4% FX + processing fees.
Accounting tip
Always log the USD-equivalent of each foreign-currency invoice in your bookkeeping using the spot FX rate on the date payment is received. This keeps your tax filings clean.
