Introduction to Finance

EVA covers a lot of operations relating money. If you ask your friendly neighborhood finance person, they will probably confirm that money is pretty important. EVA uses a system of financial periods, events, ledgers, and much, much more to keep track of all movements of value, whether it's concerning money or stock or anything else.

Financial events

Every transaction or stock mutation in EVA creates a (series of) financial event(s). Basically, a financial event is any movement of money or stock; any movement of value. Which events are triggered depends on the type or content of the transaction. Events are always generated on a transaction level. Events are structured using typical financial event types such as sales, cost of goods sold or payments.

Financial periods

A financial period is the period during which your organization unit is open for business, and for which you would like to create an entry in your bookkeeping. In most cases this period starts upon day opening, and ends upon day closing.

For any organizations using cash, opening or closing these periods involves counting the cash in your drawers and/or safes.

General ledgers

Generally, our customers already have a bunch of general ledgers in place in their ERP system. These general ledgers can be configured in EVA to support a bookkeeping setup using Cookbook.


Cookbook is a module designed to consolidate your financial events and export them as bookings on your general ledgers. The logic telling EVA how to transform your financial events into consolidated bookings is defined in so-called recipes.

For a more in-depth explanation, see Cookbook.

Tax management

Virtually every country uses tax codes, but the actual rates of the codes may differ. For this reason, country-specific rates can be defined for each tax code. For more general information see Tax management.
