Tip: type an exact cost on any row to lock it — the rest re-spread automatically.
Percentage of market freezes each card's cost at (its intake market price × the percentage). You can still override any single row afterward.
| Card | Set / No. | Cond. | Market | Cost method | Unit cost | % of mkt | Value Box status |

Inventory
Check cards, then tag them for a channel. One or a hundred — same buttons.
Scan Studio
Scan and clean your cards in PaperStream, export the images, then bring them here. Card Master pairs them, finds the card, and creates the Inventory record — it never changes the picture.
Drop cleaned card images here
JPEG, PNG or WebP — front and back, in the order they came off the scanner.
PSA submissions
Each submission is a container. Send cards, predict grades, and enter real grades when they come back.
Whatnot shows
An open show is a working tray — add and pull cards freely until you go live.
Card Shows
Reconcile how each in-person show affected the business — before, during, and after. This is a financial record, not a point-of-sale system.
Listings
Sale drafts built from inventory you already own — title, photos, condition and price in one place. Nothing here is published, and creating a listing is never a sale.
Value Boxes
Your permanent, stickered show inventory. Cards stay in their box between shows — they leave only when sold, traded, moved, or removed after review.
Purchases
Track inventory from the moment money is spent — before anything is catalogued.
Lots
Every purchase you've saved. Click a row to see the cards in it.
| Lot ID | Seller | Purchase | Date | Paid | Cards | Market | % paid |
|---|
Expenses
Business costs that aren't card purchases — supplies, subscriptions, fees, ads. Kept separate from inventory cost basis.
| Date | Vendor / payee | Category | Description | Amount | Payment | Channel |
|---|
Accounts & Cash Ledger
Every balance below is derived from an opening balance plus ledger entries — nothing here is a stored number you can edit directly.
Accounts
Settings
Application configuration. Nothing on this page moves money, posts a ledger entry, or changes a balance.
Account Connections
Marketplaces and services Card Master can talk to on your behalf. Authorizations are stored encrypted by Windows on this computer only — never in the browser, and never in a Card Master backup.
Data & Backup
Export, import, and reset your local data. Everything here operates on this browser's storage only.
Payment Profiles
How money moves — cash, Venmo, Zelle, PayPal and the rest. An account is where money is held; a profile is how it moved. Every rate here is yours to edit and every fee shown is an estimate only.
Visual Card Index
Local DINOv2 visual recognition for Scan Studio's Analyze step — a derived index built from the TCGdex catalog. Card artwork itself is never stored, only the resulting embeddings. Safe to delete or rebuild at any time.
Labs
Capabilities Card Master keeps and tests but does not put in the sidebar by default. Turning one on changes navigation only — no data, no records, and nothing about how anything is calculated. This preference lives in this browser and is never part of a backup.
