ShelfSplit

ShelfSplit is a mobile + web app that helps individuals and small resellers list used books, DVDs, CDs, and games across multiple resale channels without doing the same work repeatedly. You scan or search an ISBN/UPC, the app pulls reliable metadata, suggests a realistic price range based on recent sold comps, and generates channel-specific listing text and condition notes. It also tracks inventory, profit, and where each item is currently listed, then alerts you when something sells so you can delist everywhere else to avoid cancellations. This is not a magic “get rich” tool—margins are thin and competition is brutal—but it can save serious time for people who already source inventory and are losing hours to duplicate data entry and cross-posting mistakes. Monetization: subscription tiers based on monthly listings and marketplace connections.
