FROM SCANNED INVOICES TO CRYPTOGRAPHIC PROOF.
PayTrace reconciles the unstructured reality of business records — parsing PDF invoices, bank switch narratives, dispute emails, and procurement contracts into an immutable, court-ready evidence multi-graph.
The 5 Disparate Silos of Financial Evidence
Every payment dispute involves five isolated sources of truth that disagree on formats, timestamps, and entity names.
Switch Logs
Binary & ISO 8583 packets with raw RRNs and clearing codes.
Gateway JSONs
Webhook callbacks, capture auth tokens, and fee spread breakdowns.
PDF Invoices & POs
Scanned supplier bills, GST details, tax deductions, and payment terms.
Dispute Emails
Customer payment confirmations, attached wire slips, and claim narratives.
Bank Statements
MT940 / CAMT.053 / CSV statements with truncated remitter lines.
Layout-Aware Vision-Language OCR Pipeline
Traditional OCR outputs a jumble of disconnected text tokens. PayTrace uses a specialized Vision-Language Transformer trained on millions of corporate invoices, POs, and bank vouchers.
Preserves spatial relationships between header fields, multi-line item grids, and footer totals.
Automatically verifies: (Qty × Rate) - Discount + CGST + SGST == Total. Flags manual arithmetic tampering immediately.

# True — 0 discrepancies detectedLine-Item Table Extraction & Tax Breakdown
PayTrace extracts complex tabular matrices from multi-page documents, matching item descriptions, HSN codes, and quantities against purchase orders.
HSN & SAC Code Validation
Cross-references GST tax slabs (5%, 12%, 18%, 28%) with official tax authorities to detect rate mismatches or classification fraud.
PO vs Invoice 3-Way Match
Compares line-by-line quantities received on Goods Receipt Notes (GRN) with invoiced quantities to stop over-billing.
Multi-Currency Arbitrage Audit
Evaluates conversion spot rates (USD/INR, EUR/INR) on invoice date vs transaction date to explain FX settlement variances.
Binding Document Text to Payment Switch Records
How PayTrace binds extracted document strings (e.g., PO #4091, Invoice #8821) with binary switch logs and gateway authorization events.
OCR Identifiers
Extracts INV-8821, PO-4091, and beneficiary IFSC HDFC0000021 from PDF.
Gateway Auth Token
Matches customer checkout metadata with Gateway auth token AUTH_88921 and amount ₹8,42,000.
Bank Switch RRN
Pins RRN 881902849102 to the invoice node, establishing verifiable end-to-end provenance.
The Evidence Multi-Graph Architecture
Every piece of evidence is represented as a vertex with directional corroboration edges pointing to the central incident hypothesis.
Hypothesis #1 Corroboration Score: 96.8%
Hypothesis: "Webhook dropped post-capture + funds held in Gateway Settlement Batch SB-9018."
SHA-256 Hashes & Immutable WORM Logging
Every extracted document, raw payload, and agent reasoning step is hashed using SHA-256 and anchored in Write-Once-Read-Many (WORM) storage with RFC 3161 compliant timestamps.
INV-8821.pdf original upload checksum verified against tampering.
HDFC Core Switch debit confirmation packet timestamped 2026-09-24 14:12:08 IST.
Signed reasoning transcript ready for forensic auditor review.
Supporting vs Contradictory Evidence Matrix (Case #PT-92881)
PayTrace doesn't just collect evidence supporting a theory — our Adversarial Verification Agent actively tries to falsify findings.
