Clio's currency does not convert the money, all it does is change the sign in front of it.
When you look at the currency options if there is a symbol, it will show that symbol on your Bills, however if there is no symbol and just the acronym, then that’s what will show. ie, EUR shows the "€" symbol, but NZD shows “NZ$”.
If you update your default currency in your Clio Account, all existing time entries will switch to that currency
Changing the currency on your bill will only change the symbol of the currency on your Bill. For example if you change the currency from CAD to USD, you will not see a change as they are both $ currency.

If a client pays you via Clio Payments, it does not matter what currency your Clio Account is set to.
