The Problem

Expense tracking is tedious and consistently ignored until month-end

Piles of receipts, missing expenses, and hours spent on manual data entry are the financial operations problem every small business has.

Receipts get lost or forgotten

Paper receipts pile up, email receipts get buried, and digital receipts live in apps no one opens. Expenses go unrecorded and unrecovered.

Manual entry is time-consuming

Logging expenses into a spreadsheet or accounting system manually takes hours each month — time better spent on revenue-generating activities.

No real-time financial visibility

Without automated tracking, there's no clear picture of current spending until month-end — too late to make proactive budget decisions.

What You Get

Every node pre-configured
for production-quality output

Email Receipt Capture

Forward any receipt email to a dedicated address — the AI automatically extracts vendor, amount, date, and category without any manual input.

AI Data Extraction

GPT-4 reads receipt content (even from PDFs and image attachments) and extracts structured expense data with high accuracy.

Automatic Categorization

Expenses are automatically categorized based on vendor, description, and amount — mapped to your custom expense categories or chart of accounts.

Google Sheets Expense Log

All expenses are logged in real time to a structured Google Sheet — sortable by date, category, vendor, or amount for instant reporting.

Monthly Summary Reports

Automated monthly expense summaries are generated and delivered to your inbox — categorized totals, trend analysis, and budget comparison.

Accounting System Sync

Optional integration with Xero or QuickBooks pushes approved expenses directly to your accounting system — eliminating double data entry.
