Currencies
In order to be able to access this chapter, you need the Currencies permission.
EVA comes preconfigured with all ISO 4217 currencies, and the Currencies chapter is where you can manage those.

Clicking a currency takes you to the cash handlers overview where you can view existing handlers or create new ones.
Cash handlers
In order to be able to add cash handlers, you need the CashHandlers - Create permission. Further, to edit existing cash handlers, you need the CashHandlers - Edit permission.
Cash handlers essentially boil down to what bills and coins (denominations) are being used for a currency in a specific country.

The only facet that requires a bit of additional elaboration is how to determine your cash handlers Rounding factor. The rounding factor can be easily calculated by dividing 1
unit of your currency by its smallest denomination.
Example: In the Netherlands, the smallest denomination used is the 5 euro cents coin, which is 0.05 euros. The rounding factor for euros would then be
1/0.05
=20
.

Multiple currency organization unit(s)
There are instances where certian organization units may be accepting more than one currency as payment methods, we call those multiple currency OUs. Think of stores located at airports for exmaple, where EUR, USD, GBP, and CHF are accepted.
This can be done from the Organizations module under the financial tab.
Concept illustration
This is how a setup would look like for an organization unit that operates using two currencies.
First, you determine the currencies you wish to accept within your organization units, no surprises here. Let's assume that'll be:
Then you specify cash handlers and denominations of those currencies:
And conclude by attaching currencies to the respective organization units that would accept them.
Organization units can be either single currency operational or multi-currency.
