yeshk97/enterprise-ai-invoice-intelligence-platform — reverse-engineered prompt

Build me a working first version of an enterprise invoice intelligence platform. I want a Python first app where a team can upload invoices, run OCR, use AI to pull out key fields like vendor, invoice number, dates, line items, totals, taxes, and payment terms, then check the vendor against approved vendor data.

It should let users review the extracted results, flag low confidence items, approve or reject invoices, and keep an audit trail of what happened. Add a simple frontend so a finance user can upload files, see invoice details, search past invoices, and ask questions over invoice data using a RAG style assistant.

Please include sensible sample data, prompts, evaluation examples, security basics like user roles and safe handling of secrets, and enough docs so someone can run it locally and understand how to deploy it later. Keep it practical and production minded, not just a toy demo. Look up current docs online if you need to.
