What was that payment worth on the day?
A foreign client paid you weeks ago — but what was it actually worth in your currency on the day it landed? Pick the pair, the amount and the exact date, and get the historical exchange rate for that day. Perfect for reconciling invoices and books, not just today's headline number.
Rates provided by Frankfurter, sourced from the European Central Bank. These are ECB reference rates, published on working days only — not a live market or dealing rate, and not financial advice. It's the same feed Billable uses, so the numbers here match what you'll see in the app for the same pair and date.
One payment at a time is fine. A year of them is an afternoon you won't get back — Billable converts every foreign payment on the date it landed, from this same ECB feed.

A live converter tells you what a currency is worth right now. That's not the question you have at bookkeeping time. When a client in New York or London pays an invoice, the money lands on a specific day — and for your records, what matters is what it was worth on that day, not today. Rates move; using today's rate to record a payment from three weeks ago quietly throws your books off.
This tool answers the dated question directly. Choose the currency you were paid in, the currency you keep your books in, the amount, and the date the payment settled. You get the exact reference rate for that day and the converted figure — the number to write into your ledger, reconcile against your bank statement, or use when you calculate what you owe in tax.
Weekends, holidays and the "as of" date
The rates come from the European Central Bank, which only publishes on working days. If the payment landed on a Saturday, a Sunday or a public holiday, there's simply no rate for that calendar day. When that happens, this tool falls back to the most recent working day's rate and tells you exactly which date it used, so the number is always attributable and you can see why it isn't the date you typed.
How far back does it go?
The ECB series behind Frankfurter starts on 4 January 1999, so you can reconcile payments going back over two decades. Ask for a date before the data begins, or a currency that wasn't tracked yet, and you'll get a clear message rather than a wrong number.
Reconciling foreign payments without the guesswork
If you invoice internationally, this is the manual step that eats an afternoon at month-end: matching each foreign payment to what it was actually worth on the day, one rate lookup at a time. Billable does this for you — it tracks multi-currency invoices and what you were actually paid, using the same ECB feed, so your international bookkeeping isn't a pile of guesswork and spreadsheet tabs.
Stop reconciling foreign payments by hand.
Billable tracks multi-currency invoices and what you were actually paid — same ECB rates, no manual lookups, no signup needed to try this tool.
