Which Currency Should Your Invoice Speak? A Plain Guide

You send an invoice for 2,000. The client opens it and asks, reasonably, "2,000 of what?" If that question can come up, the invoice is already in trouble. When money crosses a border, the currency is not a detail. It decides who carries the risk of a price that moves between the day you agree and the day you are paid.

This post is about choosing a currency on purpose, so that you are not surprised by a bank statement later.

Two prices, one job

Imagine you live in a country that uses currency A and sign a project with a client who uses currency B. Between your quote and the payment, the exchange rate drifts. Someone ends up with less than they expected. The only question is who.

• If you price in your own currency, the client absorbs the drift. They may pay a little more or a little less in theirs, but your number never changes.
• If you price in theirs, you absorb it. A pleasant surprise is possible, but so is a shortfall.

Neither is wrong. What matters is choosing before the work starts and writing it down.

A simple rule for picking

You do not need a formula for each client. Ask three questions:

1. Which currency do your own costs use? If rent and tools are in your currency, pricing in it removes risk.
2. How long until you are paid? A same-week invoice barely feels a rate change. A 60-day term gives the rate time to move.
3. How much does the client care? A large company with a finance team may insist on its own currency. A small shop may be happy with whatever you choose, as long as it is a widely known one.

If the answers point your way, bill in yours. If the client insists on theirs, you can still agree, but build in some protection.

Ways to protect yourself when you bill in their currency

Suppose a copywriter quotes a monthly retainer in a client's currency. A few habits keep that safe:

• Add a small margin. Conversion fees and drift are real costs, so include them in the price, not as a surprise later.
• Shorten the payment window. Net 14 exposes you for two weeks. Net 60 exposes you for two months.
• Review the price on a schedule. For long contracts, agree to look at the rate every six months and adjust if it has moved a lot.
• Ask for a deposit. Money received up front is converted right away, so that part carries no drift at all.

Watch the fees, not only the rate

The exchange rate gets the attention, but the fees often cost more than the movement. Banks, card networks and payment services can each take a cut, and some take two. Look at what actually arrives in your account compared with what the invoice said, and do this for your first few foreign payments.

Then compare your options. You might find that one route costs a fraction of another. Also notice how fees behave: a flat charge per transfer hurts small, frequent payments. If you bill a client weekly for small amounts, one monthly invoice may keep more of your money.

Say it on the invoice

Whatever you choose, remove all doubt on paper. The invoice should show the currency next to every amount, the total in that currency, and the due date. If you agreed that the client covers transfer fees, say so in the notes. A line like "All amounts in the currency shown; the client pays any transfer charges" can save an awkward conversation.

TickPaid lets you set a currency per invoice, and its reports show what you invoiced, what came in and what is still outstanding in every currency, not blended into one confusing total. That makes it easy to see how much you are really owed in each one.

Keep the books honest

If you work in more than one currency, never mix amounts in a single column. Keep each currency separate, and note the rate you actually received when a payment lands. At the end of a quarter you will see the true effect of exchange rates on your income, which is the information you need to adjust your prices. A CSV export of your invoices also makes this simple for whoever helps with your accounts.

When to let the client choose

There is a case for flexibility. If a client's preferred currency makes them pay faster and with less friction, that convenience has value. A client who can pay in their own money without thinking is a client who pays on time. If the extra fees are small and your margin covers them, saying yes may be the smart commercial choice.

The thing to avoid is drifting into a currency by accident. Decide, write it down, and your invoices will be about the work, not about the rate.

A quick example

Picture a translator who lives in one country and works for a small agency in another. She quotes a project at a fixed amount in her own currency, adds a two-week payment window, and states both on the invoice. When the agency pays, the amount she receives matches the quote, and the only discussion is about the transfer fee, which was already agreed. Compare that with a colleague who quoted in the agency's currency, allowed sixty days, and said nothing about fees. Same job, same client, but a very different final amount. The difference came from three small choices made before any work began.

That is the whole lesson: the choices are cheap when you make them early and expensive when the invoice is already out.
