The number resellers get wrong is profit. Sold price is not profit, and neither is sold price minus what you paid. This takes off the platform fee, the payment fee and the postage you paid, then tells you how long the money sat in the item before you got it back.

WHAT YOU GET
One Excel file, nine working tabs, over 2,900 live formulas.

1. Start Here. Read it once, then you are running.
2. Setup. Every platform fee, editable, plus categories and mileage rate.
3. Inventory. The one tab you type in. Cost, repairs, listing price, days held.
4. Sales. Fees and postage taken off, profit and margin per sale.
5. Expenses. Postage supplies, mileage, subscriptions, storage.
6. Platform Performance. Which app actually pays, after its cut.
7. Category Performance. What sells, at what margin, and how fast.
8. Monthly. Twelve months of sourcing, sales, fees and profit.
9. Dashboard. Stock on hand, unrealised profit, days to sell, money tied up over ninety days.

HOW IT WORKS
Grey cells are yours. White cells calculate. Fee rates change by country, so they are inputs, not fixed numbers. Check them against the platform before you trust a result. Independent spreadsheet, not affiliated with eBay, Vinted, Poshmark or Depop.

WORKS WITH
Excel on Mac and Windows, Microsoft 365, and Google Sheets via File, Import, Upload. No add ons, no subscription.
