Frequently Asked Questions
Should I invoice in my currency or the client's?
Invoicing in the client's currency may win business (easier for them) but you bear FX risk. Invoicing in yours is simpler but clients may pay less if exchange rates move. Large clients often prefer their currency.
Where do currency exchange rates come from and how often do they change?
Major currency exchange rates are determined by the global foreign exchange (forex) market, which operates 24 hours a day, 5.5 days a week across trading centers in Tokyo, London, New York, and Sydney. Rates fluctuate continuously based on supply and demand, which is driven by interest rate differentials between central banks, inflation data, GDP figures, geopolitical events, trade balances, and market sentiment. The most heavily traded pair, EUR/USD, can move 0.5–1.5% on a typical day and 3–5% during major events like central bank policy announcements.
What fees should I watch for when converting currency?
Currency conversions typically carry multiple layers of cost: the exchange rate spread (the difference between mid-market and the rate you receive), a fixed transaction fee (common at banks, often $20–$35 per wire), a percentage commission on the converted amount, and sometimes a delivery or ATM fee. Credit card foreign transaction fees add 1–3% on top. To minimize costs: compare the effective all-in rate (including fees), use specialist transfer services for large amounts, and withdraw cash abroad from bank ATMs rather than exchange counters using a card with no foreign transaction fee.
