## The Problem

Forensic and controller teams only spot Corporate Tax fraud during annual review — and by then the pattern has compounded over 10 months of undetected leakage.

## What We Build in Corptax

AI monitors Thomson Reuters ONESOURCE transactions in real time for duplicate payments, split invoices, ghost vendors, and round-dollar patterns — flagging anomalies within 24 hours instead of 10 months. Purpose-built for teams running Corptax — uses the native API or agent integration so nothing leaves the system of record.

## Corptax Integration Approach

1. **Audit your Corptax configuration.** We map the specific Corptax objects, custom fields, and workflows the automation needs to touch for your corporate tax practice.
2. **Build on the Corptax API or agent.** Integration happens inside Corptax — no data leaves the system, no parallel tool for your team to learn, no license changes.
3. **Human-in-the-loop handoff.** Every automation routes exceptions back to a human in Corptax with full context — AI handles the 80%, your team owns the judgment calls.
