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.
