Bill and cost capture — capture actual consumption and cost from the bill, whatever its source: the building invoice, the common-area charge, the utility statement, or a PPA.

Essential-tier source-agnostic bill capture: actual consumption + cost taken from whatever bill the customer receives (building invoice / common-area 'gasto común' / utility / PPA — all treated as 'the bill'). Office analog of the retail energy bill ingestion, broadened beyond the utility statement.
