Automated Plan vs. Actual Cost Comparison Report

The Problem

Connect your accounting software (QuickBooks, etc.) and estimating tool (or Excel estimates) to automatically generate a report comparing estimated costs to actual job costs, flagging over/under budget items by category.

How It Works

Input

Exported or API-pulled actual expense data from QuickBooks (via Zapier to Airtable) and estimate data from estimating software or Excel spreadsheet

Transformation

Claude Code runs Python scripts to match estimate line items against actual costs by project, calculates variance, categorizes by trade or CSI division, and flags budget exceptions

Output

Formatted report showing each project with estimated vs. actual cost, variance amount, over/under budget status, and detailed line-item breakdowns

ReplacesBookkeeper or project controller time spent manually reconciling estimates to actuals; ~$200-$500/month in labor
