invoice_field_extractor
ChatGPTUse this tool when the user provides raw invoice text and needs deterministic structured invoice fields extracted for an order or finance processing workflow. The tool returns invoice number, supplier, buyer, invoice date, due date, currency, line items, subtotal, tax amount, total amount, billing address, payment terms, missing fields, source text, and errors. Do not use this tool to approve invoices, pay invoices, provide tax advice, provide accounting advice, generate bookkeeping recommendations, contact suppliers, send emails, modify orders, or write to external systems. This tool is useful when stable structured extraction is needed instead of an open-ended model response.
