Built for mobile card sellers
CardZen turns your phone into a card scanner. Photograph a stack from the couch, list straight to eBay, and see exactly what you made after every fee. No spreadsheets. No guessing.
Start with 15 CardSense scans or 14 days free. No credit card required.
You bought the card for $5. Paid $3 shipping. Listed it on eBay. It sold for $45. eBay took their cut. How much did you actually make? Most sellers don't know — and neither did we.
Spreadsheets fall behind after a week. Listing a stack from your phone means retyping every card by hand. The real cost is scattered across eBay, purchase receipts, and shipping invoices.
eBay fees eat more than you think. A 25% ROI on a $5 card is only one more dollarin your pocket. If you're not tracking every cost — purchase, shipping, platform fees — you're flying blind.
CardZen connects every cost to every card, so you see real margins — not vibes.
Every card, from purchase to profit
Most card apps stop at scanning. CardZen connects every step — from the moment you snap a card through listing and sale — so every cost is tracked and every margin is real.
eBay Connected
One-click eBay connection. CardZen imports your purchases with all fees, tracks every sale, and calculates actual profit — not estimated profit. Every eBay fee, shipping cost, and platform charge is accounted for automatically.
Every eBay sale, automatically reconciled with real costs.
Purchases
CardZen keeps purchase item titles, seller details, photos, shipping, tax, and fees together so cost basis is ready when cards are linked. Every purchase can become clean profit data later.
One purchase record becomes cost basis for every linked card.
Mobile Capture
Point your phone at a card — front and back. CardSense reads the card and extracts the player name, year, set, card number, and more. No typing. The card is in your system and linked to your costs in seconds.
Clear a stack of 50 cards from the couch.

Why sellers switch
Other apps scan cards. CardZen tracks your business — from the costs you pay to the profit you keep.
Your phone is the scanner. Photograph a stack of cards from the couch — front and back — and CardSense reads each one. No flatbed scanner, no desktop, no QR-code workaround. Built for the way casual sellers actually clear a stack.
Every cost is factored in: purchase price, shipping, platform fees, packaging. When a card sells, CardZen shows true net profit — not a flattering number. That $45 sale on a $5 card? After all fees, you might have made $8. Now you know.
Your listings, sales, and fees import automatically. No copying order numbers into spreadsheets. No manual reconciliation. Connect once, and every eBay transaction flows into CardZen — matched to the right card, with the right costs, showing the right profit.
Not another card scanner
Competitors focus on collection value. CardZen focuses on profit per card sold. That's a fundamentally different tool.

“The back office your card business has been missing.”
