Convert Currency Before You Quote a Foreign Client

You quoted a German client 4,000 euros in March. The euro slid, and by the time the money cleared in May you had 4,180 dollars instead of the 4,340 you expected. That 160 dollar gap was not a discount you offered. It was an exchange rate you never priced in.

Currency is one of the few decisions on a foreign quote that can quietly eat your margin after you have done everything else right. Here is how to handle the conversion before you send anything, so the number you quote is the number you can live with.

Start from the amount you actually need to bank

Work backwards. Decide the figure you need in your home currency, then convert into the client's currency, not the other way around. If you need 3,500 US dollars to make a project worthwhile, that is your anchor. Everything else is a translation of it.

Pull a live mid-market rate and run the number through a quick currency converter so you are working from today's rate, not the one you half-remember from last quarter. The mid-market rate is the honest midpoint between buy and sell. It is what you should quote from, even though you will rarely receive exactly that.

Write down both figures and the rate you used. If the client asks why the total is 3,240 euros and not a rounder number, you can show your working. When you build the quote itself, the project quote builder keeps the line items and the total in one place.

Decide who carries the currency risk

Someone bears the exchange movement between quote and payment. It is either you or the client, depending on which currency you bill in.

Bill in your own currency, and the client absorbs the swing. Their bank converts on the day they pay, so the number on your invoice is exactly what you receive (minus your own bank's fees). This is the cleaner option for you. The catch: some AP departments will not process an invoice in a currency they do not hold, or they will convert at a rate that shortchanges you if you left the choice vague.

Bill in the client's currency, and you carry the risk. You quote 3,240 euros today; if the euro drops 3 percent before they pay, you eat the difference. Larger corporate clients often prefer this because it removes work for their finance team. If you go this route, build a buffer.

A buffer is simple. Take your target home-currency figure, add 2 to 4 percent to cover a likely adverse move, then convert. On a 3,500 dollar target with a 3 percent buffer, you quote as if you needed 3,605 dollars. If the rate holds, you keep the cushion. If it moves against you, the cushion absorbs it. State your assumptions clearly, the same way you would set out any other cross-border invoicing detail.

Lock the currency on the quote, not later

Currency is one of the fields you should settle before the client accepts. On JupiterInvoice, currency is a requestable change on an invoice, which means the recipient can ask to switch it and you approve or decline. That is fine as a safety valve. It is a bad way to run every deal.

Settle it on the quote. Your quote should name the currency, the amount, and a valid until date. That date is doing real work here: it caps how long your quoted rate stays good. Quote 3,240 euros valid for 14 days, and you are not on the hook if the rate has moved by the time they come back three weeks later. When the client accepts and you convert that to a live invoice, the currency travels with it, so nobody reopens the question at payment time. The path from an accepted quote to an approved invoice is where you want the currency already fixed.

Add the details that make a foreign payment actually clear

The right currency on the invoice is only half the job. The payment has to land. For a euro payment you almost always need an IBAN and a SWIFT/BIC. Get one digit wrong and the transfer bounces back days later, after you have already counted the money as good. Run the number through an IBAN validator before it goes on the invoice.

Spell out who pays the wire fees. International transfers can carry charges on both ends, and if you do not specify, your bank may shave 15 to 40 dollars off the amount that reaches you. A line like "all bank charges to be borne by the payer" removes the argument before it starts. If you receive through a multi-currency account, quoting in a currency you already hold lets you skip a conversion entirely; that is the practical case behind using local account details for each currency.

Use the correct three-letter code, not a symbol. EUR, not a bare euro sign that could be read as any of several currencies. GBP, not just "pounds." AP teams match against codes, and the full list of ISO 4217 currency codes is worth a glance if you are billing somewhere new.

Put it into practice

Next foreign quote you write: fix your home-currency target, convert at today's mid-market rate, decide who carries the risk, add a 2 to 4 percent buffer if you are billing in their currency, and set a valid until date so the rate cannot drift under you. Then build the quote with the currency, IBAN, and code already in place, and send the client a link they can accept and act on without a single email in reply.
