Payroll Variance & Exception Review for Fractional CFOs with Fathom

Fathom Fractional CFO Outsourced Finance

The Problem

For Outsourced Finance teams, payroll runs through QuickBooks Online include silent errors — wrong pay rates, missing PTO deductions, duplicate bonuses — that only surface when an employee complains.

What We Build in Fathom

AI diffs each payroll run against the prior period, flags any variance over 5% or unusual one-time items, and holds them for approval — payroll errors caught pre-run, not post-deposit. 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 enough context to act — AI handles the 80%, your team owns the judgment calls.
