When you transfer money - there are two sums which relate to each other, the amount you send and the amount the beneficiary receives.
Between the moment you submit the transaction and until the time your money arrives in our account it can happen so that the exchange rate changes a bit.
In that situation, the amount of money received by the beneficiary will be different than what you've originally thought.
If it's important for you, that the beneficiary receives a very specific amount of money - you may 'Fix' it and we will charge you
a little extra, so called Spot Rate, to guarantee that when the money arrives at the beneficiary - it's exactly as much money as you want it to be.
