## The Problem

Employee expense reports arrive with missing receipts, wrong GL codes, and policy violations — and every rejection adds days to reimbursement and resentment to the Internal Audit team.

## What We Build in Excel

AI validates receipts against policy, auto-codes expenses, flags out-of-policy items with a clear reason, and routes approvals — expense report cycle time drops from 9 days to same-day. Purpose-built for teams running Excel — uses the native API or agent integration so nothing leaves the system of record.

## Excel Integration Approach

1. **Audit your Excel configuration.** We map the specific Excel objects, custom fields, and workflows the automation needs to touch for your internal audit practice.
2. **Build on the Excel API or agent.** Integration happens inside Excel — 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 Excel with full context — AI handles the 80%, your team owns the judgment calls.
