If you plan to charge taxes to your customers for any of your services, you must configure at least one tax service group. Aria allows you to charge taxes using the Aria Internal Tax Engine, any of Aria’s several external tax engines, or a combination of two or more of these existing tax engines.
Aria’s internal tax engine supports taxation at the State/Federal and Province/National levels. If you need more robust taxation parameters (i.e. city, municipal, etc.), you must use one of Aria’s external, third-party tax services, described in the section below.
