The business case for multi-currency at eCommerce scale
An EU-based online store selling in five countries can lose 2-3% of revenue to invisible FX fees. Here is how multi-currency banking changes the maths.
If you run an online store that ships across the EU, your checkout likely accepts EUR, GBP, perhaps CHF, SEK, PLN. Behind the scenes, the processor converts every non-EUR sale back to EUR and deposits in your home account. Each conversion carries a spread. At scale, this is not a rounding error.
The numbers
A typical processor FX spread is 1.5–2.5% versus the mid-market rate. On €1M of annual GBP revenue, that is €15–25K lost to invisible FX. Scale to €5M across multiple currencies and the number crosses €100K per year. For most eCommerce businesses this is net profit, not revenue — a 2% FX hit on a 10% net margin is 20% of your bottom line.
How multi-currency fixes it
Set up collection accounts in each major currency you accept. Payments come in and sit in that currency. You convert only when you need to pay a supplier or distribute to shareholders — at a tighter spread (0.2–0.5% at a good neo-bank) and at a timing you choose, not whenever a sale happens to clear. Match currency to currency: your UK suppliers paid in GBP, your EU suppliers in EUR, no conversion in either direction.
When it is worth the operational overhead
Rule of thumb: if non-primary-currency revenue exceeds €200K/year, the FX savings cover the extra accounting and reconciliation work. Below that, the operational simplicity of a single-currency setup usually wins.
Watch-outs
Hedge if you hold large balances in volatile currencies — a 10% movement in GBP against EUR over a quarter wipes out all your FX savings and more. Reconcile monthly, not quarterly, when you have multiple collection accounts. Make sure your accounting software supports multi-currency properly (Xero, QuickBooks, and NetSuite do; some older German/Dutch systems struggle).
What to look for in a provider
Native currency accounts (not just conversion of a EUR account). Interbank-rate FX quotes exposed before you convert. API or CSV export of transactions by currency. Reconciliation support for Stripe, Adyen, Mollie — whatever your checkout uses.
