Your card stock,
finally sold.
Cardmos turns your trading-card stock into a refined collection book — with prices, inquiries, a portfolio and a show mode. No code required.
One card, four places. No typing.
You find the card once. After that, every place you sell knows it.
Six letters typed, six fields fill themselves.
Everything for the card trade
From the first card to the show checkout — one tool instead of ten.
Inventory without typing
Search a card, set condition and price — the name, image and market price fill in automatically.
Market & portfolio
Your stock like a portfolio: price history, gainers, losers, price alerts.
Show mode
Buy, sell, check out and calculate trades with an instant price check.
Trade window
Visitors propose trades; the calculator shows the value balance.
White-label
Your own domain, colours and logo — your shop, your brand.
Daily prices
Market prices from Cardmarket via CardNexus, refreshed every day.
One system for everything cards
Collect, value, sell – it all connects. Pick an area and take a look.

More in the cosmos
Three places where the collection book becomes a scene.
I built Cardmos because as a collector and dealer, I couldn't find a tool as beautiful as the cards themselves.
