Sports Card Inventory App with AI Capture, Cost Tracking & eBay Profit
Spreadsheets break when your collection grows past a few hundred cards. CardZen is an AI sports card inventory app built for sellers: scan with any camera, track every dollar from purchase to sale — including fees, grading costs, and eBay payouts — and list without copy-paste chaos.
What Breaks When Your Collection Grows
Most collectors start with a spreadsheet. It works for 50 cards. By 200 it is slow and error-prone. By 500 you are losing money because you cannot track cost basis, fees, or profit per card accurately. Common problems:
- Duplicate entries and inconsistent naming across rows
- No connection between your inventory and eBay listings or sales
- Grading submissions tracked in a separate doc or not at all
- No real profit calculation — you guess at margins instead of knowing them
What a Real Sports Card Inventory App Should Track
A price guide is not an inventory system. You need to track the full lifecycle of every card — from the moment you buy it to the moment you sell it.
Player, Year, Set, Number
Standardized card identity so you can search, sort, and filter across your entire collection.
Purchase Price and Cost Basis
What you actually paid — including shipping, tax, and any lot-splitting math.
Current Condition and Grade
Raw, graded, or pending. Track PSA, BGS, SGC grades and population data.
Listing Status and Platform
Know which cards are listed, where, and at what price — without checking eBay separately.
Sale Price, Fees, and Net Profit
eBay fees, shipping costs, and final payout calculated automatically.
Location and Storage
Which box, binder, or safe — so you can actually find the card when it sells.
Card Scanning and Photo Capture
CardZen's CardSense AI reads sports cards from any camera — phone, webcam, or DSLR — and auto-fills player, year, set, number, and condition. Point, scan a stack, review pairs. No proprietary scanner lock-in.
Unlike scanner-dependent apps, you are not locked into a specific device. Use whatever camera you already own.
Cost Basis, Fees, and Profit Tracking
Every card in CardZen carries its full cost history. When you sell, the app calculates your actual profit after eBay fees, shipping, and platform costs. No more guessing whether a flip was profitable.
Want the fee math before you connect eBay? Use the eBay sports card profit calculator. For a deeper look at the full cost stack, read our guide on the true cost of collecting.
Grading Workflow Tracking
Mark cards for grading, choose a destination (PSA, BGS, SGC), and track them through the submission pipeline with a kanban board. When grades come back, update the card and see the ROI impact immediately.
eBay Listing and Sales Workflow
Connect your eBay account and CardZen syncs your listings and sales automatically. List cards directly from your inventory, set prices with comp data, and track every sale through to payout. No copy-pasting between tabs.
See how the full workflow comes together in our comp pricing guide.
Spreadsheet Import and Export
Already tracking cards in a spreadsheet? Import your CSV and CardZen maps your columns automatically. You can also export your full inventory at any time — your data is never locked in.

Frequently Asked Questions
- Is CardZen free to use?
- Yes — CardZen starts with a free trial: 15 CardSense scans or 14 days, whichever comes first, with every feature unlocked and no credit card required. After that, Starter ($17/mo) and Pro ($30/mo) both include every feature — they differ only in how many CardSense scans you get each month.

- Yes. CardZen supports CSV import so you can bring in your existing inventory from Google Sheets, Excel, or any other spreadsheet tool without re-entering data.

- Yes. CardZen integrates directly with eBay to sync your listings, track sales, and calculate profit after fees. You can list cards to eBay directly from your inventory.
- How do I scan cards into the app?
- Use any camera — phone, webcam, or digital camera. CardZen uses AI to read your card and auto-fill player name, year, set, card number, and condition details.
- Does CardZen track grading submissions?
- Yes. You can mark cards for grading, track them through submission to PSA, BGS, or SGC, and update their status as they move through the grading pipeline.
- What makes CardZen different from CollX or Ludex?
- CardZen is built for sellers and serious collectors who need cost-basis tracking, profit calculations, grading workflows, and eBay integration — not just a price guide or scanner.

Choose InVelocity if you need deep TCGPlayer pricing and restock suggestions; choose CardZen if you want sports-card workflow + knowing true eBay take-home.
