Multi-Currency Invoicing Guide
Working with international clients often means dealing with multiple currencies. This calculator helps you combine costs in different currencies into a single invoice while understanding the conversion implications.
When Multi-Currency Invoicing Matters
- International clients - Billing across borders in their preferred currency
- Subcontractor costs - Combining work from global team members
- Software/tools - Many SaaS tools bill in USD regardless of your location
- Travel expenses - Reimbursing costs incurred in different countries
Best Practices for Currency Conversion
Document the exchange rate used and the date. This prevents disputes if rates change before payment.
Use rates from your bank, payment processor (PayPal, Wise, Stripe), or a recognized source like XE or Google.
Display original amounts, exchange rates, and converted totals. Transparency builds trust and simplifies reconciliation.
International transfers often incur fees (1-3%+). Factor these into your pricing or add a payment processing fee.
Common Currency Scenarios
Invoice in USD (your preference) or EUR (easier for client). Consider which party assumes exchange risk.
Pay contractors in their currencies, convert all costs to your billing currency for client invoices.
Many tools charge in USD. Combine with local currency work, convert all to client's currency.
Keep receipts in original currency, convert using the rate on the transaction date for accuracy.
Invoice Line Item Examples
| Item | Original | Rate | USD |
|---|---|---|---|
| Design work | €500 EUR | 1.08 | $540 |
| Development | £800 GBP | 1.27 | $1,016 |
| Hosting (annual) | $120 USD | 1.00 | $120 |
| Total | $1,676 | ||
Payment Methods for International Invoices
- Wise (TransferWise) - Low fees, mid-market rates, 50+ currencies
- PayPal - Convenient but higher fees (2.9% + currency conversion)
- Bank Wire - Best for large amounts, fees vary by bank
- Stripe - Accept cards in 135+ currencies, converts automatically
Pro Tip: For ongoing international clients, consider opening a multi-currency account (Wise, Payoneer). This lets you hold and receive funds in their currency, converting only when rates are favorable.
Frequently Asked Questions
Should I invoice in my currency or my client's?
Generally, invoice in the currency you want to receive payment in. Invoicing in your local currency puts the exchange rate risk on your client. Invoicing in their currency may make payment easier for them but exposes you to exchange rate fluctuations.
How do I handle exchange rate fluctuations?
Lock in rates at invoice creation, include the exchange rate on the invoice, and set clear payment terms. For large amounts or long payment terms, consider adding a clause allowing rate adjustment if currency moves more than 5%.
What exchange rate should I use?
Use the rate from your bank or payment processor, as that's what you'll actually receive. Mid-market rates from Google or XE are reference points, but banks typically add 1-3% markup. Document the rate source on your invoice.
Do I need to show both currencies on the invoice?
It's best practice to show the original amounts and the converted total. This transparency helps clients verify calculations and understand what they're paying. Include the exchange rate used and the rate date.
How do I handle partial payments in different currencies?
Record payments at the exchange rate on the payment date. You may receive slightly more or less than expected due to rate changes. Track the difference as foreign exchange gain or loss for accounting purposes.
