## The Problem

Senior reviewers spend hours tick-and-tying Cost Accounting returns against source documents and prior year — and small-dollar variances still slip through into partner review.

## What We Build in Power BI

AI reconciles each line of the return against source docs in SAP S/4HANA and the prior year, explains variances over 5%, and produces a review workpaper the senior can sign off on — cutting review time in half. Purpose-built for teams running Power BI — uses the native API or agent integration so nothing leaves the system of record.

## Power BI Integration Approach

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