We need to provide accounting teams with a report that totals up all of the defined payment schedules on all/any invoices and aggregates/totals the $ amount for each month; this is used for cashflow analysis.

Could be part of the invoice export (which currently does NOT included payment schedule data) or could be part of the reporting module inside the system.

Payment schedule information (dates, and dollars due) is in a table in a database somewhere inside the system, and needs to be easily reported on.
