FlipperHelper: Resell Tracker

FlipperHelper is the free inventory and profit tracker built for resellers — the people who buy at car boot sales, charity shops, thrift stores, flea markets, estate and garage sales, then resell on eBay, Vinted, Depop, Facebook Marketplace and more.

Snap a photo, log what you paid, mark where you listed it, and record the sale. FlipperHelper does the maths — showing your REAL profit after every fee, entry cost, and expense. No spreadsheets, no formulas, no guesswork.

IMPORTANT: FlipperHelper is a tracker, not a cross-listing tool. It doesn't post listings for you — you list on each platform yourself, then track everything in one place.

HOW IT WORKS
• Buy — snap a photo at the market; log price, market, and seller. A unique SKU is generated automatically.
• List — mark which of 16 platforms you've listed on, with per-platform dates.
• Sell — record the sale and see your profit instantly.
• Review — the Money Flow dashboard shows revenue, costs, and real profit by week, month, or custom range.
