Answer: The prebuilt-invoice analyzer for procurement
prebuilt-invoice is the domain analyzer for invoices, utility bills, sales orders, and purchase orders, and it adds document processing without training a model first. prebuilt-receipt covers retail and dining receipts, a different document type with a different schema. prebuilt-documentFieldSchema proposes a schema for a new document type rather than returning values. A custom analyzer needs the labeled documents the team does not have.
