CASE STUDY / BIDonBOT
Reseller intelligence
Putting the buy-or-pass decision in the thrift-store aisle.
BIDonBOT is a free, no-signup reseller toolkit for item recognition, live eBay comps, marketplace fee math, pricing, and listing help.
01 / THE PROBLEM
Start with the real decision.
A reseller usually needs an answer before buying the item—not later at a desk. The useful question is not only what an item lists for, but what remains after fees, shipping, and cost.
The research is fragmented across image search, marketplace tabs, fee charts, calculators, and listing notes. That makes a simple sourcing decision slower and easier to misread.
02 / PRODUCT DIRECTION
A smaller, sharper workflow.
Let a reseller photograph an item or type its name, then put current eBay listings and the important price range in one fast result.
Carry the result directly into platform-specific profit math for eBay, Poshmark, Mercari, Depop, Facebook Marketplace, and OfferUp.
Keep the core workflow free and accountless so it works at a garage sale, thrift store, or estate sale with almost no setup.
03 / WHAT SHIPPED
A working product, not a concept page.
- Camera and photo-upload item recognition
- Text search with live eBay listing comps
- Marketplace fee and net-profit calculator
- Reverse pricing planner based on target profit
- Listing templates, photo checklist, and weekly workflow
- Resale-value guides for the brands thrifters actively research
04 / PUBLIC EVIDENCE
What someone can verify today.
- The complete scan, comp, and profit workflow is available on the public homepage without signup.
- Every result is framed as decision support: condition and sold-listing demand still matter, and no sale price is guaranteed.
- The calculator and guides expose the assumptions behind their fee math instead of hiding the numbers in a score.
