# Financial Due Diligence Prep for Fractional CFOs with Fathom

> AI standardizes TB data across periods, builds the QoE model, identifies add-backs with source-document evidence, and drafts the data-book — senior analysts focus on judgment calls, not reformatting. Purpose-built for teams running Fathom — uses the native API or agent integration so nothing leaves the system of record.

## The Problem

Quality-of-earnings work for Outsourced Finance targets starts with 18 months of trial balances and a dozen schedules that need normalization before any adjustment can be proposed.

## What We Build in Fathom

AI standardizes TB data across periods, builds the QoE model, identifies add-backs with source-document evidence, and drafts the data-book — senior analysts focus on judgment calls, not reformatting. Purpose-built for teams running Fathom — uses the native API or agent integration so nothing leaves the system of record.

## Fathom Integration Approach

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