DocuFlow: Turning Invoice PDFs into Structured Financial Data

说明与用途

DocuFlow 使用 Docker、Celery、Tesseract 和 PostgreSQL 自动提取 PDF 发票数据，并在 Streamlit 中可视化结果。

问题

Invoices stored as PDFs in a folder are difficult to process at scale; manual extraction is error‑prone and duplicate detection is missing.

结果

The pipeline processes hundreds of invoices automatically, eliminates duplicate processing, and provides real‑time analytics without blocking the UI.

工作流

• Watch hot folder for new PDFs
• Queue task to Redis via Celery
• Asynchronous worker runs Tesseract + Poppler to extract text
• Parse extracted text for invoice fields (number, date, vendor, total)
• Store parsed data in PostgreSQL
• Query data from Streamlit dashboard for analysis

证据

DocuFlow is a containerized, event‑driven pipeline that automates ingestion, OCR, parsing, and analytics for invoices and financial documents.
