Fraud & Forgery Detection

Document Tampering and Forgery, Caught While the Document Is Read

Every document is verified as it's processed. No separate fraud tool, no second pass, no extra step.

Tampered and Altered Documents

Edited amounts, changed dates, and modified fields are flagged with the altered region highlighted for your reviewer.

Duplicates Across Every Channel

The same invoice or cheque submitted twice, in different formats or through different channels, is caught before payment.

Cheque Forensics: 10 Checks Per Leaf

Every cheque runs up to 10 automated checks, from signature authentication to alteration and washing detection.

Fake and Fabricated Documents

Statements and documents that never came from their claimed source are flagged and routed to review, not to your ERP.

Built for the Documents Your Industry Actually Runs On

Industry-specific processing, fraud checks, and audit trails, working out of the box.

Vendor invoices and reconciliations at retail volume.

  • High-Volume Invoice and Credit Note Processing
  • Vendor Statement Reconciliation
  • Fake and Duplicate Invoice Flags
  • Marketplace and ERP Integrations

At our volume, even a small error rate meant a full-time cleanup job. That job doesn't exist anymore.

Stop approving loans on documents nobody verified.

  • Template-Free Loan and KYC Processing
  • Bank Statement Checks for Tampering
  • 10 Forensic Checks on Every Cheque
  • Straight-Through LOS and Core Integration

It flagged an altered payee name our team had already passed. That one catch justified the year. Never though an IDP solution will include Fraud detection

Claims move faster when the documents prove themselves.

  • Claims Document Extraction, Every Format
  • Altered and Fabricated Bill Flags
  • Policy and KYC Pack Processing
  • Direct Claims System Integration

Our assessors used to spend more time typing than assessing. Now the documents arrive extracted, checked, and ready to decide on.

Stop chasing invoices and delivery notes across emails, portals, and FTP folders.

  • Bill of Lading Data Extraction
  • Bulk Shipment File Auto-Splitting
  • Automated PO and Invoice Reconciliation
  • Real-Time ERP and TMS Integration

  • Supplier Invoices in Any Layout
  • Duplicate and Altered Invoice Detection
  • SAP, Oracle, and Tally Connectors

Patient forms, purchase records, and compliance documents, without the data entry.

  • Multi-Format Medical Document Extraction
  • Batch and Compliance Record Processing
  • Duplicate Invoice and Bill Flags
  • Confidence-Scored Human Review

Compliance documentation used to be our slowest process. KlearStack turned it into something we don't think about.

Vendor invoices and reconciliations at retail volume.

  • High-Volume Invoice and Credit Note Processing
  • Vendor Statement Reconciliation
  • Fake and Duplicate Invoice Flags
  • Marketplace and ERP Integrations

At our volume, even a small error rate meant a full-time cleanup job. That job doesn't exist anymore.
