How to Invoice International Clients (and Actually Get Paid)
Winning a client in another country is a milestone. Then the first invoice goes out and the money comes back short, or late, or stuck somewhere in a bank you have never heard of. Cross-border billing has a few extra traps that a local invoice never does: which currency to use, who swallows the exchange difference, who pays the wire fee, and what paperwork the client's country expects. Get those right and an overseas client is no harder to bill than one down the road. Here is how to do it.
Agree the currency before you start, not on the invoice
The single biggest cause of a short payment is a currency muddle. Decide, in writing, which currency you are billing in before any work begins, ideally in the quote. If you invoice in your own currency, you always know exactly what you will receive and the client carries the exchange risk. If you invoice in theirs, you make it easy for them to pay but you take on the risk that the rate moves against you between the invoice and the payment.
There is no universally right answer, but there is a right process: pick one, say so up front, and put it in your quotation so nobody is surprised. If you agree to bill in a foreign currency, add one line to the contract stating how the exchange rate is set, for example the rate on the invoice date, so a wobble in the market never turns into an argument.
Show the currency on every amount, and use a real due date
On an international invoice, never write a bare number. Write the currency code next to every figure, so "USD 1,500" or "EUR 1,500", not just "1,500". A dollar sign alone is ambiguous when your client is in a country that also uses dollars, and a plain number invites a costly mistake. The currency code removes all doubt.
Do the same with the deadline. "Net 30" is read differently around the world, and time zones make "30 days" fuzzy. Use an absolute date instead, "Due by 17 October 2026", so there is one unambiguous deadline no matter where the client sits. Clear dates are also what make a polite reminder easy later, and if it ever comes to that, our guide on what to do when a client does not pay walks through the steps.
Make it easy, and cheap, for them to pay you
The more friction there is in paying you, the longer you wait. A traditional international wire is slow and expensive, and the fees often come out of your money rather than the client's. Where you can, offer a cheaper rail: a multi-currency account that gives your client a local bank transfer to make, or a payment platform that handles the conversion, can drop the cost of getting paid to under one percent and the wait from days to hours.
Whatever method you use, put the full details clearly on the invoice: account name, account number or IBAN, any routing or SWIFT code, and the exact reference you want them to quote. Bury this at the bottom in small print and you invite delay. Put it where it cannot be missed and you get paid faster.
Spell out who pays the transfer fees
This is the detail that quietly eats your invoice. On an international transfer, the bank charges can be paid by the sender, split, or taken out of the amount being sent, and if you say nothing the client's bank will often pick the option that leaves you short. The fix is one sentence on the invoice.
State plainly that the sender covers all transfer charges, sometimes shown as the "OUR" option, so the full amount reaches you. A simple line like "All bank and transfer fees are the responsibility of the payer" does the job. It feels small, but on a large invoice it is the difference between receiving what you billed and receiving what the banks left behind.
When you need a proforma invoice
Cross-border work is where the proforma invoice finally earns its place. If your client has to clear goods through customs, get internal sign-off, or pay you before you deliver, they will often ask for a proforma: a formal confirmation of the agreed items, quantities and total that is not yet the final bill. It lets the money and the paperwork start moving before the real invoice exists.
If you are hazy on how a proforma differs from a quote, an invoice and a receipt, the full breakdown is in our guide to what to send and when. The short version: send a proforma when someone needs to act before delivery, then replace it with a proper invoice once the deal goes ahead, because only the invoice is the real, recordable request for payment.
Keep the same clean paper trail as a local job
International clients need the same four documents as anyone else, and skipping steps is what causes disputes across a language barrier. Send a quotation to win the work and lock the currency, send the invoice to bill it, and send a receipt once the money lands so both sides have proof the deal is settled, which matters even more when you cannot pop in for a chat.
The good news is you do not need special international software for any of this. Remit makes quotes, invoices, proformas and receipts in any currency from one free account, with your logo and bank details built in. Send a quote to agree the terms, an invoice to get paid, and a receipt to close it, without retyping anything or switching tools between countries.
A quick pre-send checklist
Before you send that overseas invoice, run down this list. Is the currency code shown next to every amount? Is there an absolute due date rather than "Net 30"? Are your full payment details, including SWIFT or IBAN where needed, easy to find? Have you stated that the payer covers the transfer fees? And does the invoice number, issue date and itemised breakdown leave no room for doubt?
Tick those five and you have removed almost every reason an international payment arrives late or short. Cross-border billing rewards clarity more than anything else, so say exactly what you mean, show every currency, and make paying you the easy option. Do that and getting paid from abroad stops being a worry and becomes just another invoice.
