Marge: Reseller Profit

Know your real profit — after every fee.

Marge is the professional-grade reseller tool that starts simple. Log what you bought, what you sold, and the fees in between — and see exactly how much you actually made on every flip. Then, when you're ready to run it like a business: P&L statements, expense and mileage books, inventory valuation, and tax-ready reports. Beginner-friendly on day one, a powerhouse when you go full-time.

Marge is descriptive, not prescriptive: it reports your numbers. It never gives advice or moves your money.
