ExpenseIn uses a third-party exchange rate and currency conversion service which updates to the current exchange rate every three hours from Currency Layer, a well-known and widely used currency source. 

To allow users to enter their own exchange rate on their expense, an Account Administrator can enable the 'Users can override the exchange rate' setting in the Additional Settings section of the Admin area.

The option to add your own custom exchange rates is also available in the Admin area. Custom exchange rates will be used in place of the real-time rates provided by our third-party software.
