By default, Rydoo uses the exchange rate of Openexchangerates.org, for all expenses made in foreign currencies. This is calculated based upon the date on the receipt or invoice.
As an Admin, you can configure settings to increase the exchange rate with a premium on top of the base exchange rate.
How to configure this as an Admin:
1. Go to Admin settings.
2. Go to Advanced settings page.
3. Check the right checkbox, fill in the right premium and don't forget to save
