How to make an invoice in multiple currencies

People mix up two jobs: picking the currency that appears on the invoice, and converting money before they type the prices. This site’s invoice generator only does the first job. You set a currency on the document, enter quantities and unit prices in that currency, and export a PDF. It will not quietly rewrite lines when exchange rates move.

Invoice currency versus “convert first”

Invoice currency is the unit printed on totals: USD, EUR, INR, and so on. Every line should already be in that unit.

Convert first, then invoice means you decide the quoted price in another currency (or from a mid-market style screen), settle on a number with your client, and only then enter that number as the unit price. The currency converter helps with that prep step. It does not sit inside the invoice form.

If bank fees confuse the prep quote, read currency conversion fees vs mid-market rate before you lock a number.

Worked example (USD, three lines)

Imagine a small consulting invoice billed in USD, with tax and discount left at 0% so the arithmetic stays obvious:

From the invoice calculator:

• Subtotal = 360
• Discount total = 0
• Tax total = 0
• Grand total = 360

Those figures are the same whether you label the document USD or another currency code. The label tells the reader which unit you mean; it does not convert anything.

A clean workflow

1. Agree with the client which currency the invoice will use.
2. If your internal quote was in a different currency, convert (and apply any fee you were actually charged) offline or with the converter, then round to the money unit you will print.
3. Open the invoice generator, set that currency, and enter each line.
4. Preview and export the PDF. Keep a note of the rate date if your contract cares.

What not to do: enter local-currency prices, switch the currency dropdown at the end, and expect the totals to magically jump to another unit. That path is not supported.

Line math

With tax and discount at zero, each line total is quantity × unit price. When both are on, the calculator applies the discount percent first, then calculates tax on the reduced amount. Those percents are not currency conversions; they are the same percentage fields whether you billed USD or another code.

If you need a fourth line at a different price, add it and let the grand total update. The worked example stays at three equal lines so you can verify 360 by eye. When you later add tax, re-check the PDF preview: the currency symbol in the header should still match the unit you typed in every row.

What the tool does and does not do

The invoice generator lets you fill business and client fields, add line items with quantity, unit price, tax percent, and discount percent, choose one currency for the document, preview, and export a PDF. It does not fetch live exchange rates, does not rewrite line prices when you change the currency dropdown, and does not store a history of which mid-market quote you used while preparing the number.

That boundary is the whole point of this guide. If you need a rate first, use the converter (and fee math if your bank quoted a percent), agree the figure, then type it. If you need the fee story next, open the currency fees article linked above.

Build it in the tool

Set currency to USD, add three lines at 120, leave tax and discount at zero, and confirm the grand total shows 360 before you export.
