Abiquo Billing Integration Plugin is a separate java utility that can aggregate accounting (metered) data as well as any other data from the Abiquo database and presents it to a billing system. The accounting data can be aggregated to different levels (hourly, daily, weekly, monthly).
The Abiquo Billing Integration Plugin can outputs billing data in generic formats, or to specific billing systems (push or pull). Billing data can be done at either or both VDC or Enterprise level. Multiple billing integration plugins can be ran with different parameters for different 'streams' of data to support different billing needs.
