Challenge
Brazilians living abroad don't know what a euro expense really cost, since each transfer has a different rate, spread and fee.
Solution
Each transfer is a lot with its effective rate; each expense consumes lots by FIFO and shows its cost in reais; monthly budgets; CSV statement import; unit and end-to-end tests with CI.
