## The Problem

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

## What We Build in Bill.com

AI reconciles each line of the return against source docs in NetSuite 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 Bill.com — uses the native API or agent integration so nothing leaves the system of record.

## Bill.com Integration Approach

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