Billing Email

If a field called "Billing Email" exists and is populated, then all invoices a profile may generate will be emailed to the address specified here.

Invoice Organisation

If the "Invoice Organisation" checkbox is checked then any invoices created by a profile will be made out to the organisation with the profile's first and last name used in the "Attention:" field.
Alternatively, if this field is un-checked, then the invoice will be made out to the individual and the organisation name will not appear on the invoice.
