Our Customers

Why having current rates is important?

Behavioral Psychology tells us that people tend to "strike while the iron is hot", and in that mood they usually disregard the tiny details, such as - the price is sweeter, because it's in "stronger" currency. Common example is U.S. Dollar vs Canadian or Australian dollars, though in modern global economy, it's usually U.S. Dollar vs Euro. Your customer from another country may think that your price is higher than of competitor, but if only you would be able to display it in his currency, along with original one, the wind could change.

Therefore most our customers are from global sales - real estate, shops, hotels, as well as all kinds of creative studios.

Frequesntly Asked Quedtions

This section is the main reason why our support assistants don't have anything to do
most of the time

01. Can I cancel my subscription?

You can cancel the next renewal any time. It only takes one click. Two, actually. You can also renew it any moment later.

02. My currency is not in the list, can you add it?

If we missed a currency, as it happened in the past, we can add it any moment, just let us know.

03. How often the rate is refreshed?

We say - every 12 minutes, but usually it's even quicker than that. In fact, it's different for each currency, as it depends from natural factors and world events.

04. What is your source of data?

We are partnered with two financial institutions in Sweden, that provide us with live feeds. We then analyse and "blend" them together using our own algorithms.
