About FlipStock - Reseller Profit Tracker
FlipStock is an inventory and profit-tracking app built for resellers and flippers — eBay, Poshmark, Vinted, Depop, and garage-sale sellers who count every dollar and refuse monthly software fees on principle.
THE TRUE-PROFIT REVEAL Enter a sold price once, and FlipStock shows your real profit after platform fees, shipping, and original cost — per item, and rolled up per month. No more guessing whether that "sold for $45" item actually made you money.
HOW IT WORKS 1. Log an item as you acquire it — photo, cost, source, and storage bin 2. Track it through drafted, listed, sold on whichever platform you used 3. Record the sale — sold price and shipping — and fees compute automatically 4. Watch your true profit, sell-through rate, and stale-stock aging update instantly
INVENTORY BUILT FOR FLIPPERS - Item tracking — photos, purchase cost, source (thrift store, auction, lot), date acquired, storage bin/location code, condition notes - Lot splitting — buy a $50 box of 20 items and split the cost across them automatically (even, weighted, or manual) - Listing tracker — per-platform status (drafted / listed / sold / returned) with listing date, entered by hand — no fragile platform APIs to break - Configurable fee profiles per platform (percent + fixed + payment fee) so your profit math survives the next fee change - Storage bin tracking — assign items to a bin/location code and manage every bin in a simple list (code, label, notes, item count)
DASHBOARDS THAT KEEP YOU HONEST - Profit this month, average days-to-sell, and sell-through rate at a glance - Stale-stock aging report — flags items sitting past your chosen threshold - "Death pile" total — the real cost of everything still unsold in your storage - Year-end CSV export of your sales, expenses, and mileage detail, ready to hand to a tax preparer
YEAR-END, HANDLED One click produces a year-end report — total revenue, cost of goods sold, fees, mileage, and profit — formatted for a tax preparer as both PDF and CSV.
YOUR DATA, YOUR DEVICE FlipStock works fully offline — your inventory, listings, and sales never touch a server you don't control. It's a one-time purchase: no subscription, no monthly fee eating into margins that are already thin. Everything lives in a file on your own computer.
FLIPSTOCK IS PERFECT FOR: - eBay, Poshmark, Vinted, and Depop sellers who need real numbers, not vibes - Thrift-and-flip side hustlers splitting bulk lot costs across dozens of items - Anyone who has ever sold something and had no idea if they actually profited - Resellers who dread January and want a tax-ready report in one click - Sellers tracking storage bins across a garage, unit, or spare room full of inventory
