# Money values
Money values are objects consisting of amount and currency fields, e.g.
{
    "amount": "500", 
    "currency": "EUR"
}
The amount is usually in EURO cents, e.g. 5 EUR * 100 = 500 cents. The only
exception to the rule is Invoice.rows[...].unit_price which  is as fractions
so 5 EUR * 1000 = 5000 because some industries are invoicing with that
precision.
NOTE: Currently only EUR is supported as currency.
