STRUCTURED OCR & DATA COLLECTION

Turn unstructured invoices into clean, reliable data

Kolosal converts invoices, purchase orders, receipts, and service documents into structured JSON using a visual-language model (Qwen 3 VL 30B). This lets you standardize fields like invoice number, dates, suppliers, line items, taxes, and totals. Ready for validation and analytics.

THREE-WAY MATCHING ENGINE

Three-way matching that finds mismatches before payment

The Matching Engine compares purchase orders, goods receipts, and invoices to detect:

  • Amount discrepancies
  • Quantity mismatches
  • Date anomalies
  • Duplicate payments
  • Missing documentation
  • Supplier and pricing anomalies

String similarity matching and confidence scoring so even if item names or SKUs don’t match perfectly, suspicious gaps still surface, with a match score that lets reviewers focus on low confidence, high risk transactions first.

MACHINE LEARNING ANOMALY DETECTION

ML models that learn what “normal” looks like

Once data is cleaned and matched, it flows through anomaly-detection and ensemble models that learn your normal behavior and highlight deviations. Each transaction gets a risk score and classification (low, medium, high), so investigations stay focused.

In a real-world dataset of 5,778 purchase orders, ML identified 4,971 (≈86%) as low-risk and 807 (≈14%) as suspicious, split into high- and medium-anomaly cases. A focused shortlist instead of thousands of items.

Who Kolosal fraud system is for

Fraud detection use cases

01

Preventing invoice overbilling & duplicate payments

Automatically detect invoice amounts that exceed purchase orders, duplicate invoices across vendors or branches, and suspicious rapid payments on high-value transactions.

02

Strengthening three-way matching controls

Enforce three-way matching between POs, receipts, and invoices for both goods and services. Identify missing documentation, quantity mismatches, and date anomalies that signal control gaps.

03

Detecting retail and inventory fraud

Cross-check sales flow, accounts payable, and company stock to surface discrepancies that point to shrinkage, manipulation, or collusion. Focus investigations on the 9–15% of transactions where risk truly concentrates.

04

Service fraud & pricing manipulation

Detect excessive discounts, high-price items, open price manipulation, instant service completion, and after-hours services that bypass normal approvals and controls.

05

Supplier & customer behavior monitoring

Spot high-value outliers with rarely used suppliers, repeated abuse by a small group of customers, and missing paperwork on big deals — early indicators of systematic fraud.
