Which rate this is
The European Central Bank publishes euro foreign exchange reference rates once each working day, at around 16:00 CET, based on a regular daily concertation between central banks. They are the closest thing to a neutral, published, citable rate — which is exactly why they are used here, and exactly why they are not the rate you will be charged.
Reference rates are not dealing rates. A bank, a card network or a payment provider applies its own rate plus a margin, and that margin is frequently the larger part of the difference between this figure and the one on your statement. Treat what this page shows as indicative — good enough to price something, not good enough to reconcile one.
Selling in more than one currency
Sellstamp does not convert anything. A price in a second currency is a number you set per product, and the customer is charged that number, so there is no rate to go stale between the page and the receipt and no rounding that disagrees with their bank. This converter exists to help you choose the number — after that it is a price like any other.
Questions
Where do the rates come from?
From the European Central Bank’s euro foreign exchange reference rates, published once each working day at around 16:00 CET, read through the free Frankfurter API.
Why is my bank’s rate different?
Banks, card networks and payment providers use their own rate plus a margin. The reference rate is a neutral benchmark, not a rate anyone will actually exchange at.
How current is the rate?
The ECB publishes once each working day and not on weekends or its holidays. This page checks at most once an hour, so it is never more than an hour behind a publication.
Which currencies can I convert?
The currencies the ECB publishes reference rates for, about thirty. Currencies it does not cover are not available here.
Can I use this rate on an invoice?
As an indication, yes. For accounting, use the rate your bank or tax authority specifies; many tax authorities publish their own official rates.
