## The Problem

For Cross-Border Tax teams, payroll runs through ONESOURCE include silent errors — wrong pay rates, missing PTO deductions, duplicate bonuses — that only surface when an employee complains.

## What We Build in ONESOURCE

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 ONESOURCE — uses the native API or agent integration so nothing leaves the system of record.

## ONESOURCE Integration Approach

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