Currency converter for invoices: which rate to use and how to note it

When you invoice a client in one currency but think in another, a second number helps. QuoteBill’s currency converter shows your invoice total in another currency, using the European Central Bank’s daily euro reference rates or a rate you type yourself. It is indicative: it is not the rate a bank or a payment provider will give you. Where to find it In the invoice editor, under the tax section, a closed panel called Convert the total opens the converter. The same converter is also a page of its own under Tools, in 33 languages. Where the rates come from The European Central Bank publishes euro reference rates, about thirty currencies, with one fixing for each working day. QuoteBill shows the rate together with its date, so you can see how fresh it is. A conversion between two currencies that are not the euro is worked out through the euro. These cross rates are indicative. Typing your own rate If you agreed a rate with your client, or your bank quotes you one, type it instead, and the converter uses yours. The invoice itself does not change: the panel only shows a figure until you decide what to do with it. Adding a note to the document Press Add a note to the document and one line is added to the notes. For example: Equivalent: JPY 150,000 ≈ USD 998.40 at 1 JPY = 0.006656 USD (European Central Bank reference rate of 2026-10-02). For information only. The note is added once, it carries the rate and its date, and it says that it is for information only. Delete it from the notes if you change your mind. What it does not do The converter does not change your invoice’s currency or its amounts. To bill in a different currency, set the Currency field on the document. Every amount then prints with its code, such as USD 5,120.00, and totals and rounding follow that currency: the yen has no decimals and the Kuwaiti dinar has three. A currency the bank does not publish a rate for cannot be converted automatically, so type a rate yourself. If the rate service is not available, the panel says so and your invoice is unaffected. Which rate should you use? That depends on what you and your client agreed and on your country’s rules. Many businesses state the rate and its date on the invoice or in the contract, and some tax authorities publish rates of their own for converting an invoice. QuoteBill does not decide this for you. When it matters, ask your accountant. Open the converter - Currency converter: https://quotebill.com/en/tools/currency-converter/ - All tools: https://quotebill.com/en/tools/
