Verikata

AI-enabled SaaS solution for federal invoice, claims, and payment integrity workflows.

The Challenge

Modern payment integrity requires speed, control, and evidence

Federal agencies process millions of invoices and claims each year against contracts, fee schedules, coding rules, and regulatory requirements. Much of that validation still depends on spreadsheets, email threads, manual sampling, and legacy workflows that are difficult to scale, monitor, or defend.

These fragmented processes slow reimbursement cycles, increase improper payment risk, and limit visibility for Contracting Officers, auditors, program leaders, and oversight teams.

The Solution
Verikata helps agencies move from manual review to software-defined payment integrity — bringing high-volume invoice, claims, and payment integrity workflows into one configurable platform.
Platform Capabilities

How Verikata Works

Verikata centralizes payment integrity workflows from intake through disposition. The platform normalizes incoming data, applies program-specific business rules, identifies anomalies and emerging risk patterns, and gives teams a unified workspace for review, documentation, reporting, and oversight.

Secure Data Ingestion

Normalizes vendor submissions, claims files, EDI transactions, flat files, and other source data into a consistent data model. Intake processes initiate SLA tracking and support encryption at rest and in transit.

Governed Data Foundation

Maintains versioned, timestamped records with full audit history. Transactional data, decision records, and reviewer actions are preserved to support transparency, oversight, and defensible reporting.

Configurable Compliance Rules

Runs transactions against program-specific business logic, including pricing, coding, service, structural, contractual, and regulatory rules. Each rule can be tied to a defined authority so reviewers understand what triggered the flag and why it matters.

Explainable AI/ML Detection

Uses XGBoost and SHAP explainability to surface anomalies and emerging risk patterns beyond known rule violations. Each score can be broken down by the features that contributed to the result, giving reviewers visibility into how the model reached its recommendation.

Human Review Workspace

Provides role-based workspaces for reviewers, auditors, supervisors, and executives. Reviewers can disposition records, document rationale, manage bulk actions, and create a complete audit trail. Reviewer decisions are captured as ground-truth labels and fed into scheduled retraining cycles so model accuracy improves with operational use.

Optional Natural Language Query

Verikata can be extended with a natural-language query capability that enables users to explore validation data, audit history, reviewer actions, and decision records through conversational search. Extensions can also support vendor self-service workflows and legacy system integrations.
