What We Built & Why

AI Invoice Processor is a fully automated invoice data extraction platform that monitors a designated folder (local system or Google Drive) for new invoices and processes them instantly. Using a combination of OCR and LLM-powered parsing, it extracts key fields — vendor name, amount, tax, due date, invoice number — and stores structured data in a database.

The system handles invoices in PDF, PNG, JPG, and JPEG formats regardless of layout or vendor — eliminating hours of manual data entry and ensuring 100% consistent, structured records every time.

Core problem solved: Finance teams spend hours manually re-typing invoice data from PDFs and images into spreadsheets or ERP systems. This platform reduces that to zero manual work — every invoice is parsed, summarised, and stored automatically within seconds of upload.

Any Format

Handles PDF, PNG, JPG, JPEG — regardless of vendor layout or design.

Smart Extraction

Vendor, amount, tax, due date, invoice number extracted automatically.

File Monitoring

Watches folder 24/7 — triggers processing the moment a new file appears.

Database Storage

Parsed data stored in structured DB — ready for querying and analysis.

Invoice Processing System — Dashboard

Drag & Drop Upload + Live Stats

The dashboard shows real-time invoice stats — 105 total invoices, 0 processed (pending batch), 33 pending. Users drag & drop any invoice file and the system processes it automatically.

· Supported: PDF, PNG, JPG, JPEG
· Extracted fields: Vendor, Invoice No., Date, Amount, Currency
· Features: OCR, AI-powered field parsing, Excel export
· RESTful API endpoints available at /invoices

The Automated Invoice Pipeline

From file detection to structured database storage — every step is fully automated. No manual trigger, no human review required.

01
File Monitoring

System watches the designated folder (local or Google Drive) 24/7 and detects any newly uploaded invoice file instantly.

02
Invoice Upload

PDF, PNG, JPG, or JPEG invoice file detected and loaded into the processing pipeline automatically.

03
OCR Extraction

Optical Character Recognition converts invoice images and PDFs into machine-readable text — capturing all visible fields.

04
LLM Parsing

LLM (OpenAI) intelligently parses the raw OCR text — identifying and extracting vendor, amount, tax, date, and invoice number.

05
Summary Generation

Structured summary of the extracted data created — all key fields captured in a clean, consistent format.

06
Database Storage

Parsed invoice data and summaries stored in the database (SQL/NoSQL) — fully indexed for fast retrieval and analysis.

07
Excel Export

Processed invoice data exported to Excel automatically — ready for finance teams to download and use immediately.

08
Processing Complete

Invoice fully processed — zero manual input, zero data entry. Dashboard stats updated in real time.
