Built for TCG vendors
The operating system for Pokémon card vendors
Price lookups, inventory, transactions, and card shows — all in one place. Stop juggling five tabs and a spreadsheet.
Everything you need to run your hobby like a business
Generic inventory software wasn't built for card shows. leftovers.gg was.
Real-time price estimates
Every estimate is backed by actual eBay sold listings from the last 90 days — not a static database number that's two weeks old.
Inventory without the spreadsheet
Add cards through the catalog, log conditions, and always know what you're holding and what it's worth at current market prices.
Log every transaction in seconds
Buys, sells, and trades — including complex multi-card trades with cash components. Inventory and P&L update automatically.
Find and prep for card shows
See upcoming shows near you, register as a vendor, and let customers know what you're bringing before they walk in the door.
Price Estimator
Know what any card is worth — and why
Search any card, pick the condition, and get a price estimate built from real eBay sold listings in the last 90 days. Not a static price guide. Not a black box.
You control the methodology: median, recency-weighted, trimmed to remove outliers, or IQR-filtered. See exactly which sales went into the number.
Graded cards are supported too — PSA, BGS, and CGC with grade-level comps.
