This category includes any differences earned or paid between when you input your invoice, to when you either pay or get paid for them.
What's included
An FX gain will arise when the exchange rate changes in a favourable direction between the date you raise the invoice and the date your client pays you.
An FX loss will arise when the exchange rate changes in an unfavourable direction between the date you raise the invoice and the date your client pays you.
A gain or loss will be unrealised until payment is received. When paid the unrealised gains or losses will crystallise and become realised.
What's not included
Unrealised gains or losses will not appear in Ember until you are paid for the invoice you have outstanding. At which point the gain or loss will become realised.
