## The Problem

Invoices arrive via email, PDF, mail, and vendor portals — Corporate Tax Managers re-key them into Thomson Reuters ONESOURCE, chase GL codes and approvers, and still end up with duplicates and late fees.

## What We Build in Corptax

AI pulls bills from every channel, extracts line items, assigns GL codes using Corporate Tax patterns, routes approvals, and sends payment files to Thomson Reuters ONESOURCE — processing cost per invoice drops from $15 to under $2. 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.
