Why This is an Opportunity

The reseller community (eBay, Poshmark, Depop, vintage shops) is massive, growing, and woefully underserved by tools that understand how they actually buy inventory. The lot-based accounting model is a genuinely novel angle that no existing tool nails.

Key Pain Points

  • You bought a storage unit lot for $500 and have no idea if you've made your money back yet
  • Tracking individual item costs from bulk purchases in a spreadsheet is a nightmare
  • You think you're profitable but you've never actually calculated your hourly rate for sourcing trips
  • Existing inventory tools assume you buy items one at a time, not in chaotic mixed lots

Original Discovery

Vintage sellers, flea market flippers, and estate sale pickers buy inventory in weird bulk lots and have no idea if they're profitable until months later. OddLot lets you log a purchase lot (paid $200 for a box of 30 items at an estate sale), then track individual item sales as you list and sell them. It shows you a live P&L per lot, your best item categories, and your true hourly rate for sourcing. It's the financial clarity resellers desperately need but are too busy thrifting to build in a spreadsheet.
