Getting paid across borders without the bank eating your margin
Cross-border payments quietly cost EU solos 3–5% in hidden FX. Here is how the multi-currency setup actually works — and where the money leaks.

The first time a US client paid me, the invoice said one number and my bank credited a smaller one. No fee line — just a worse exchange rate than the real one. That gap is the single most ignored cost in a one-person cross-border business.
Where the money actually leaks
- The FX spread. Banks quote you a rate 2–4% worse than the mid-market rate and call it “no fees”. The spread is the fee.
- Double conversion. Client pays USD → bank converts to EUR → you spend in EUR. Sometimes it converts twice. You pay each time.
- Incoming wire fees. Flat charges that hurt most on smaller invoices.
The setup that fixes most of it
Hold a multi-currency account with local receiving details in the currencies your clients use. Then you get paid like a local in USD, GBP or EUR, hold the balance, and convert only when the rate suits you — at the real mid-market rate.
For most EU solos this is the boring, correct answer:
Open a multi-currency accountNot sure which account to open first — or whether you need a separate business account at all? I lined up the options in best business bank accounts for EU freelancers.
What the spread actually costs: a worked example
Numbers make it concrete. Say you invoice a US client $2,000 and the real mid-market rate would give you €1,850. Here’s the gap, depending on how you receive it:
| Route | Effective FX cost | You receive (approx) |
|---|---|---|
| High-street bank, ~3% spread | ~€55 | ~€1,795 |
| PayPal-style conversion, ~4% | ~€74 | ~€1,776 |
| Multi-currency at mid-market | ~€0 spread (small fixed fee) | ~€1,845 |
One invoice, up to ~€70 difference. Repeat that across a year of foreign clients and you’re donating a holiday’s worth of money to a spread you never agreed to.
A simple rule of thumb
If more than ~20% of your income arrives in a currency you don’t spend, a multi-currency account pays for itself in the first few invoices.
What this is not
A multi-currency account is a money layer, not accounting. It won’t do your VAT, your OSS, or your bookkeeping — keep those separate (see the invoicing & accounting roundup). Mixing the two is how solos end up with a shoebox of FX screenshots at quarter-end.
Bottom line
You can’t control your clients’ currencies, but you can stop donating 3–5% of every foreign invoice to a spread you never agreed to. Fix the money layer once; it keeps paying you back.
