Executive Summary // Architecture Brief

PRODUCTION SPECIFICATION

An autonomous document intelligence pipeline reading invoices, contracts, and delivery receipts from emails and supplier portals. Features text-first parsing with OCR fallback, strict Pydantic extraction schemas with bounding-box citations, external deterministic arithmetic and 3-way PO matching, straight-through posting to Odoo/SAP, and an exception review cockpit.

CAPABILITY 01PRODUCTION READY

Evidentiary Bounding Box Extraction

Every extracted value maps to exact page coordinates with side-by-side source highlighting.

CAPABILITY 02PRODUCTION READY

Deterministic 3-Way Match

Code-driven verification of vendor, PO number, line items, and goods receipt notes.

CAPABILITY 03PRODUCTION READY

Dual-Channel ERP Dispatch

Idempotent posting via REST APIs with Playwright browser automation for legacy portals.

CAPABILITY 04PRODUCTION READY

Exception Review Cockpit

Review screen displaying low-confidence fields beside highlighted source regions for instant 1-tap confirmation.

The Accounts Payable Bottleneck

Finance and accounting teams receive thousands of invoices, contracts, and delivery notes each month via disjointed email inboxes, supplier portals, and scans across multiple languages and layouts. Accounting staff spend days manually retyping line items into ERP systems, causing costly month-end reconciliation errors: duplicate payments, inaccurate VAT/tax rates, and purchase order mismatches. Off-the-shelf OCR breaks on novel layouts, while unguided LLMs hallucinate calculations with zero warning.

Deterministic Code Decides, AI Only Proposes

We engineered an immutable, audit-grade ingestion pipeline built on Python 3.11 and FastAPI. Attachments are hashed with SHA-256 upon arrival. Text-first extraction runs with neural OCR fallback, mapping fields into a strict Pydantic schema with exact source page and bounding box region coordinates. Crucially, calculations, line-item arithmetic, and three-way matches against purchase orders and goods receipts are computed by deterministic code outside the LLM. Clean records post directly into ERP APIs; discrepancies land in a side-by-side review UI with the source region highlighted.

Production Architectural Guarantees

  • SHA-256 immutable document ledger ensuring untrusted document text can never alter execution logic
  • Page-level bounding box coordinate capture for every extracted line item, tax value, and vendor entity
  • External deterministic arithmetic verification and automated 3-way matching against purchase orders and receipts
  • Dual-mode ERP posting: direct REST API integration with headless Playwright automation fallback for legacy portals
  • Automated regression evaluation harness executing curated 10-document benchmark suites on every prompt update
Evaluation Suite Included: Includes a regression test set covering clean, duplicate, foreign-language, scanned, and mismatched invoices.

“
★★★★★5.0 Verified
✓ Zero-Hallucination SLA • Multi-LLM Swarms

“Vijay and the SHIVAM ITCS AI team didn't just execute the project - they elevated our entire platform. Their ability to architect complex multi-agent state machines, eliminate latency bottlenecks, enforce zero-hallucination guardrails, and create an intelligent multi-LLM orchestration layer was extraordinary. The final delivery was resilient, battle-tested, and far beyond expectations. One of the strongest AI systems engineering teams in the industry.”
