CardZen

Snap cards, list on eBay, see your real profit

CardZen is the back office for people who sell sports cards. Snap a stack with your phone and CardSense reads the player, year, set and card number off the front and back, turning a shoebox of raw inventory into structured data in minutes instead of an evening of typing. From there it plugs straight into eBay. Purchases, fees and sales sync automatically, listings are created from inventory you already have, and every card carries its true cost basis: what you paid, plus shipping, tax and platform fees. The result is the number most sellers are guessing at. Real net profit per card, and a running P&L across the whole operation. Built for side-sellers and small dealers who want to run this like a business instead of a spreadsheet.
