You probably have already noticed we don't charge any fees to send money home for mobile money transfers. It's our goal to make sending money home to your loved ones as cheap as possible.
We use the mid-market rate as a baseline for all transfers. We then add a very tiny percentage markup on the exchange rate that you see on the main page of the application. This helps us get close to covering our costs for running NALA.
We will soon be launching business services soon!
