Every Invoice Checked 5 Ways Before It Reaches Approval
Expand a scenario to see the specific check that catches it, and what happens next.
Totals, line items, and tax arithmetic are cross-checked on every invoice. Figures that disagree stop the invoice before approval.
What OCR Tools And LLMs Miss, KlearStack
Is Built To Catch
Generic OCR, IDP Tools, and LLMs
These tools read a document and return the data. Whether that document is genuine is a question they never ask.
- Extraction only, no authenticity checks
- LLMs: a different answer on every run
- Documents leave for external APIs
- No audit trail a regulator accepts
Every document is read, then interrogated: forensic checks, signature authentication, and cross-references run inside the same pass, and every result is logged.
- Forensic fraud checks in the same pass
- Deterministic results, every single run
- On-prem and private deployment options
- Field-level audit trail, ready for review

One Screening Pass Inside the AP Flow You Already Run
Here’s how KlearStack becomes a part of your workflow
Before KlearStack
Approved on Familiarity
Invoices from known vendors clear on sight. A convincing fake under a known name rides through.
Sampled Matching
Three-way matches cover big amounts and spot checks. The rest clears on trust.
Duplicates Found at the Statement
The second payment surfaces in the vendor statement, months after the money left.
Fraud Discovered at Audit
The fabricated invoice turns up in the audit sample, with the trail gone cold.
Every invoice passes the same checks automatically, inside the AP flow it already follows.
- Every invoice matched, not sampled
- Duplicates caught at submission, not at the statement
- Flags raised before payment, not after
- Every check logged, audit-ready
- No new step for your AP team
The Fastest Way Through AP Is a Convincing Invoice
Fraudulent invoices are built to ride routine approvals. Three gaps every AP queue lives with.
Volume Hides the Fake
An AP team clearing hundreds of invoices a day approves on pattern recognition. A convincing fake matches the pattern.
Duplicates Survive a Rename
The same invoice, rescanned or renamed, reads as new. It gets paid twice and found on the vendor statement.
The Match Is Partial
Three-way matching by hand covers samples and big amounts. Everything below the threshold clears on trust.

Invoice Fraud
Detection
An invoice is checked as real or fake through matching and file forensics. A genuine invoice matches its purchase order and goods receipt. A fake one fails the match or shows pixel-level edits. KlearStack flags both before the invoice reaches approval.
