In Upflow, you have an organization default currency, which displays the amounts whenever there is an aggregation (Organization outstanding amount, customer outstanding amount, etc.). We do this by taking the rate from [fixer.io](http://fixer.io/), and by refreshing it daily. We use today's rate across all currency conversions. Upflow historical analytics are based on today's rate and might differ from analysis using historical FX rates. Additionally, when the displayed amount contains several currencies, we will display a breakdown of each currency and the converted amount.
