Invoicing across borders
International invoicing adds a few layers of complexity compared to domestic billing — currency decisions, tax implications, longer payment timelines, and different payment method preferences. But with the right approach, it's straightforward. This guide covers the key decisions you need to make.
Choosing the invoice currency
You have three options:
- Invoice in your local currency — simplest for your bookkeeping. The client handles conversion. Risk: the client may delay payment if the exchange rate is unfavorable.
- Invoice in the client's currency — easier for the client to pay. You bear the exchange rate risk. Best for landing and keeping international clients.
- Invoice in USD — a common middle ground, especially in tech, consulting, and creative industries. USD is widely accepted and relatively stable.
Whichever you choose, agree on the currency before starting work and state it clearly on every invoice. Include the three-letter currency code (USD, EUR, GBP) next to amounts — don't rely on $ or € symbols alone, as they can be ambiguous.
International payment methods
Different regions prefer different payment methods. Offer at least two options to make it easy for your client:
- Wise (TransferWise) — lowest fees for international transfers (0.5-1.5%). Your client sends in their currency, you receive in yours. Best option for regular international work.
- PayPal — widely accepted globally but fees add up (2.5-4.5% for cross-border transactions). Convenient for smaller invoices.
- International wire transfer (SWIFT) — works everywhere but is slow (3-5 business days) and expensive ($15-45 per transfer, sometimes on both ends). Best for large invoices where the fee is proportionally small.
- Payoneer — popular for freelancers working with US companies from abroad. Good rates, slower setup.
- Cryptocurrency — increasingly accepted for tech/creative work. Fast, low fees, but volatile. Agree on the conversion rate at time of invoice.
Tax considerations
International tax rules vary significantly. Here are the general principles:
If you're in the US
Services provided to clients outside the US are generally not subject to US sales tax. You don't need to collect or remit foreign taxes — that's the client's responsibility in their jurisdiction. Include your EIN on the invoice for the client's records.
If you're in the EU
B2B services to clients in other EU countries use the "reverse charge" mechanism — you don't charge VAT, and the client accounts for VAT in their country. Include your VAT number and the client's VAT number on the invoice, along with the note "Reverse charge — VAT to be accounted for by the recipient." For clients outside the EU, services are typically zero-rated (no VAT charged).
If you're in the UK
Similar to the EU post-Brexit. Services to overseas business clients are outside the scope of UK VAT. Include your VAT number and state that the supply is outside the scope of UK VAT.
Always consult a tax professional familiar with international taxation for your specific situation.
Formatting tips for international invoices
- Use the full date format — write "March 17, 2026" not "03/17/2026." Date formats differ by country (US: MM/DD, Europe: DD/MM), and the full format eliminates confusion.
- Include currency codes — write "USD 5,000" not "$5,000." The dollar sign is used by multiple countries.
- Add your international bank details — for wire transfers, include your IBAN, SWIFT/BIC code, bank name, and bank address.
- State payment terms clearly — international payments take longer. Consider Net 30 minimum (Net 15 may be too tight for cross-border processing).
- Include both addresses — your full address and the client's full address, including country.
Dealing with exchange rate fluctuations
If you invoice in a foreign currency, you're exposed to exchange rate risk. Here's how to manage it:
- Use shorter payment terms — the faster the client pays, the less time for the rate to move against you.
- Add a currency clause — specify that the rate is based on the exchange rate on a specific date (invoice date or payment date).
- Build in a buffer — some freelancers add 2-3% to their rates for international clients to absorb potential exchange rate losses.
- Use Wise or similar services — they offer mid-market exchange rates with transparent fees, so you know exactly what you'll receive.
