# Multi-State Sales Tax Filing for Construction Bookkeepers

> AI monitors nexus thresholds, pulls transaction data from Sage 100 Contractor, prepares state-by-state returns, and logs filings with evidence — nexus risk is tracked in real time, not discovered at audit.

## The Problem

Tracking nexus across 30+ states for Construction Accounting clients and filing the right return on the right cadence is a full-time job — and one missed Wayfair threshold triggers back-taxes and penalties.

## What We Build

AI monitors nexus thresholds, pulls transaction data from Sage 100 Contractor, prepares state-by-state returns, and logs filings with evidence — nexus risk is tracked in real time, not discovered at audit.

## How It Works

3. **Review & refine.** You review the results, we fine-tune until it matches your standards, then it runs on autopilot.
