Using multiple entities

You can choose to use more than one financial entity with the Billing module. Multiple entity processing is necessary when you keep more than one set of financial books.

Multiple entity processing is set up through the AR Cash module, but the association of specific Billing products with entities is accomplished using the Billing module.

You can combine products whose income is assigned to different entities within the same billing cycle. This can be used to keep the income of subsidiaries separate, or to keep fundraising and non-fundraising income separate while sending only a single bill to your customers.
