Marge: Reseller Profit

Apogee Labs

In-app purchases

About this app

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.

BUILT FOR THE WAY YOU FLIP
• Source → list → sell pipeline, with per-sale marketplace fees, shipping and other costs
• Net profit, ROI%, margin and days-to-flip on every item
• Portfolio scoreboard: all-time profit, money tied up, best categories and platforms
• Buy in one currency, sell in another — totals stay straight
• Lots / quantities, returns, and partial sales

FAST TO LOG
• Add a buy in seconds — only name and cost are required
• Scan a product barcode to fill the item
• Import your eBay/Vinted/spreadsheet history (CSV or Excel) with smart column detection — buys AND sales
• Snap the item + receipt and let AI pre-fill the details, including quantity

RUN IT LIKE A BUSINESS (Pro & Expert)
• Pro: AI photo scan, unlimited items, full insights, and monthly profit goals
• Expert: profit & loss statements, an expense ledger, mileage tracking, inventory valuation, and a tax-ready year-end summary you can export

PRIVATE BY DESIGN
• Works with no account — your inventory lives on your device
• Optional sign-in (Google, Apple or email) syncs across your devices; delete your account anytime
• No ads, no tracking, no selling your data
• Export everything to CSV anytime — even on Free

Available in English, French, Spanish, German and Portuguese.

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