EUR vs. USD: Which Currency Should EU Freelancers Bill International Clients In? (2026 Guide)

1. Should You Bill International Clients in EUR or in USD, GBP & CHF?

Every European freelancer landing a contract in San Francisco, London, or Zurich faces the same negotiation question: "Should I quote my rate in Euros (€) or in the client's currency ($, £, CHF)?"

Because your rent, health insurance, VAT, and income tax advances are paid in EUR, billing in EUR feels like the safest choice. However, forcing a US or UK accounts payable department to send Euros abroad creates friction that can cost you either the contract or 3% to 5% of your invoice value:

The Golden Rule for EU Solopreneurs

• For Swiss (CHF) and UK (GBP) clients: If the client can send EUR via SEPA at low cost, invoicing in EUR is clean and effortless. If they prefer CHF or GBP, accept it via a multi-currency account and include our Article 44 non-EU VAT clause.
• For US (USD) clients: Almost always offer to bill in USD via local ACH into your Wise or Revolut USD routing/account number, and bake a 2% currency buffer into your USD rate. Never ask a US client to send USD via SWIFT to a traditional German, Spanish, or French Euro IBAN.

3. The Hidden Costs of SWIFT, PayPal & Traditional Banks vs. Local Multi-Currency Rails

Most banks advertise "€0 incoming wire fee" while quietly taking 2.5% to 4.0% inside a marked-up exchange rate spread. Here is what actually happens to a $5,000 USD invoice across the four most common payment channels used by European freelancers:

Why SWIFT "SHA" Transfers Break Your Invoice Accounting

When a US or Swiss client wires money via SWIFT using default SHA (Shared) instructions, their bank hands the payment to one or two intermediary correspondent banks on its way to Europe. Each intermediary slices $15 to $25 directly off the transferred principal. You invoice $5,000, but $4,960 arrives before conversion.

If a client must pay via SWIFT instead of local ACH, always include this line on your invoice: "All bank and intermediary SWIFT transfer fees are borne by the sender (SWIFT instruction: OUR)."

4. Statutory ECB Exchange Rate Rules for Tax & VAT (DE, ES, FR, NL, CY)

Once your USD, GBP, or CHF invoice is paid, how do you record it in your European tax return? Tax offices across the Eurozone do not allow arbitrary monthly averages when you operate on a cash basis:

5. How SoloTreasury Automates Multi-Currency & ECB Payment-Date Tracking

Whether you bill €5,000 to Berlin, $6,000 to New York, or CHF 4,500 to Zurich, tracking multi-currency invoices manually across bank CSVs and ECB rate tables is tedious. Here is how SoloTreasury Freelancer Edition (€49 one-time) handles it inside your own Google Sheet:

1. Log Invoices in EUR, USD, GBP, or CHF. Enter the original invoice amount and currency in Smart Invoicing.
2. Automatic ECB Reference Rate on the Payment Date. When you mark a foreign-currency invoice as paid, SoloTreasury converts the invoice into EUR using the official European Central Bank (ECB) reference rate for the payment date.
3. Separate Non-EU Revenue from Domestic VAT. Third-country B2B invoices (US, UK, Switzerland) are flagged at 0% VAT so they never inflate your domestic VAT liability while still flowing into your income tax and social contribution reserve math.
4. True Net Spendable Cash. After setting aside your country-specific income tax, health/social contributions, domestic VAT, and safety buffer, the dashboard shows the exact Euro amount safe to transfer to your personal account.
