For card flippers, collectors & investors

Know what you actually made.

Not what your cards are "worth" — what you really cleared after fees, grading, shipping, and what you paid. Cardbooks tracks every buy, sale, and expense, shows your true profit on one clean dashboard, and has your CPA report ready before April. Your spreadsheet is retiring.

The Card Flipper's P&L Spreadsheet is the tracker I built for my own flipping when nothing better existed — using it is what convinced me an app should. It's free when you join the waitlist, and founding-member pricing comes with it. One email at launch, nothing else.

And when April shows up, you're already done.

Every profit number Cardbooks shows you is built from real records — cost basis, fees, dates. That means tax season stops being a project. One click, and your CPA gets everything they need. (Yes, your profit is taxable even without a 1099-K — and a few states still send forms at low thresholds.)

Federal threshold
$20K + 200 sales
Most flippers get no form — but profit is still taxable
Some states

MA & MD send forms at $600; NJ at $1,000 — others vary
With Cardbooks

Gains, expenses & reconciliation — a report your CPA will actually accept

Per IRS Form 1099-K guidance updated after the 2025 threshold change. Not tax advice — confirm your situation with a tax professional.

Why this exists

I'm a collector and flipper. I wanted one place to log what I bought, what I spent on grading and shipping, what I sold, and what I actually made — with a clean report to hand my CPA in April.

It didn't exist. Everything out there tracks what cards are worth. Almost nothing tracks what they cost you — and nothing produces records a tax preparer can work from. So I built myself a spreadsheet. It's the one you get free on this page — and living in it is exactly what convinced me this should be an app.
