Built for card sellers
CardZen shows your real profit
on every card you sell.
Connect your eBay, import your sales, and see exactly what you made after all fees — purchase, shipping, grading, eBay's cut. No spreadsheets. No guessing.
Free forever. 25 AI credits included. No credit card required.
You're selling cards.
You don't know if you're actually making money.
You bought the card for $5. Paid $3 shipping. Sent it to PSA for $20. Shipped it again. 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. Most card apps track collection value, not business profit. The real cost is scattered across eBay, grading invoices, and shipping receipts.
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, grading, 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
The connected lifecycle
other apps don't have.
Most card apps stop at scanning. CardZen connects every step — from the moment you buy a card through grading, listing, and sale — so every cost is tracked and every margin is real.
Connect eBay. See where the money goes.
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.

Why sellers switch
Three things no other
card app does.
Other apps scan cards. CardZen tracks your business — from the costs you pay to the profit you keep.
Real margins, not guesses
Every cost is factored in: purchase price, grading fees, shipping, platform fees, packaging. When a card sells, CardZen shows true net profit — not a flattering number. If a card lost money, it tells you honestly. That $45 sale on a $5 card? After all fees, you might have made $8. Now you know.
eBay synced, always current
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.
AI that saves time, not just scans
Snap a photo and AI reads the card. Drop a receipt and every line item gets logged. The AI isn't the product — it's the engine that eliminates data entry so you can focus on buying, grading, and selling. Not typing.
Not another card scanner
Other apps scan your cards.
We track your business.
Competitors focus on collection value. CardZen focuses on profit per card sold. That's a fundamentally different tool.
CardZen is not
- Another card scanner. Scanning is table stakes. If all you do is identify cards, you’re still stuck doing the real work yourself.
- A collection tracker. We don’t estimate what your cards are worth. We track what you paid, what you sold for, and what you actually kept.
- A price guide. No trending alerts. No “up 40%!” notifications. CardZen tracks your business, not the market.
- A marketplace. You sell on eBay. We’re the back office that tells you if those sales are actually profitable.
CardZen is
- Real profit on every card after ALL fees — purchase, shipping, grading, eBay
- eBay integration that imports purchases, tracks sales, and reconciles automatically
- AI that reads cards and receipts so you skip the data entry
- Grading workflow across PSA, BGS, and SGC with full cost tracking
- The only card app built for sellers, not collectors
“The back office your card business has been missing.”
