Buy smarter. Track real profit. Without spreadsheets.
The decision and analytics platform for Cardmarket sellers who want to understand which purchases actually made money-including grading fees, shared costs, and long-term performance.
You still list and sell on Cardmarket.
TCG Clerk makes sure every decision behind those listings is backed by data.
Cardmarket gives you prices.
TCG Clerk gives you answers.
Knowing a card sold isn't the same as knowing it was profitable.
TCG Clerk connects evaluations, purchases, grading, inventory, offers, and sold orders into one continuous workflow-so profit is calculated automatically, not reconstructed later in Excel.
Profitability at the purchase level
Cards don't exist in isolation. Purchases do.
TCG Clerk tracks profit per purchase, not just per card-so you can clearly see which deals worked, which didn't, and why.
If you bought it together, you should evaluate it together.
Built-in grading workflow
Grading adds upside-but also cost, time, and risk.
TCG Clerk treats grading as a first-class workflow, tracking every fee and its impact on the final margin.

Record grading fees and service levels
See how grading changes final sale price
