  • Whether it identifies cards for you or you type them in.
  • Whether it lists inventory to eBay and other marketplaces.
  • What it costs at a seller's volume.

The tools

1. CardDealerPro: sellers listing raw cards in bulk

Software that identifies cards from scanner or phone images, builds an inventory, and lists the cards on eBay and other marketplaces. From $9/month; 7-day free trial.

Inventory built from scans, listed to eBay, Shopify, Whatnot and CollX. CardDealerPro compared with HobbyGM.

2. Kronozio: card shops

An AI inventory manager for trading cards and other collectibles, with its own marketplace at kronozio.com and plans sized by how many cards you add and list on eBay each month. From $10/month; 7-day free trial.

Inventory, identification, eBay listing and its own marketplace, with plans from about 500 to over 100,000 new items a month. Kronozio compared with HobbyGM.

3. CollX: collectors who sometimes sell

A phone app that scans and values cards, tracks your collection, and has its own marketplace where collectors buy and sell. Free; Pro $9.99/month.

Free collection tracking with values, and a marketplace built in. CollX compared with HobbyGM.

4. Card Ladder: tracking a collection's value

A sold-price database and collection tracker for sports and Pokémon cards, with sales history from several marketplaces. Free; Pro $19.99/month in the app.

Collection values from sales across marketplaces. Card Ladder compared with HobbyGM.

5. HobbyGM: an eBay store you already have

A web app for eBay card stores. It connects to your store through eBay's official API, checks every listing each night, fixes titles and item specifics in bulk, and sends offers to watchers. Free to connect your store.

Not inventory software. If every card you sell is already listed on eBay, it works on that store directly.
