Who it's for

Resellers and flippers who sell across multiple marketplaces (eBay, Poshmark, Mercari, Depop, Etsy, Amazon, Facebook Marketplace, Whatnot, Vinted, StockX) and want to know, before they list or buy, where an item actually nets the most money after fees.

What you get

  • Multi-platform net take-home comparison — paste an item's cost, expected sale price, and shipping cost; get a side-by-side table of estimated fees and net take-home across up to 10 marketplaces, ranked highest take-home first.
  • BUY / PASS / BORDERLINE sourcing call — enter your target margin (or use the 30% default) and get a clear call on whether an item is worth buying, with the full math shown: cost -> fees -> net take-home -> margin vs. target -> breakeven price.
  • Cross-listing strategy memo — which platform to list on first for the fastest sale vs. the highest take-home, plus the minimum price to protect your margin on each platform.
  • Sourcing research checklist — a step-by-step manual routine for pulling real sold-comp prices, catching hidden costs (packaging, mileage, cleaning, returns, tax), and flagging condition/authenticity risk before you buy.

Why one-time beats a $20-55/month tool

Most reseller profit tools are subscriptions ($20-55/mo for Amazon-only sourcing scorers, $9-45/mo for cross-listing automation). This is a one-time purchase: paste your numbers, get the comparison and the call, no recurring fee, no account linking.

What this is NOT

  • Not a live price-scraping or market-data service — it does not fetch real-time prices or connect to any marketplace API.
  • Not automatic listing or inventory sync — you still list the item yourself.
  • Not investment advice and not a guarantee of profit or sale. BUY/PASS/BORDERLINE is a calculation against the margin you set, not a prediction that an item will sell.
  • No API key, no login, no personal data required — item and price details only.

2026 fee data note

The built-in fee reference table reflects each platform's published rates as of 2026 (eBay, Poshmark, Mercari, Depop, Etsy, Amazon, Facebook Marketplace, Whatnot, Vinted, StockX). Marketplaces change fees without much notice, so always confirm the current rate on the platform's own fee page before a high-value sourcing decision — this skill repeats that reminder on every comparison table.
