HobbyGM vs List Perfectly

List Perfectly is a crosslister with a catalog of your listings that lists to eBay, Poshmark, Mercari, Depop, Etsy, Facebook, Grailed, Shopify and other marketplaces. It suits resellers who sell general goods across several marketplaces.

HobbyGM is 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.

What HobbyGM does

• Checks every listing in your store each night: titles, item specifics, and cards with no watchers three weeks after listing. (how the checks work)
• Fills missing item specifics from the title and adds missing search terms (parallel, print run, grade, team) to titles, in bulk, with review before anything is pushed to eBay.
• Flags listings whose title and item specifics disagree: card number, season, print run, autograph, rookie, grade.
• Compares each card's price with other sellers' current listings of the same card, matched on number, parallel, grade and print run.
• Sends offers to watchers in bulk, or automatically each night by your rules, never below break-even.
• Shows each listing's net margin after eBay fees, shipping and supplies, and flags cards that lose money or would ship cheaper by Standard Envelope. (fee calculator)
• Reads per-listing traffic from eBay, so you can see which cards get seen and not clicked.
• Covers sports cards, Pokémon, Magic, Yu-Gi-Oh!, One Piece, Lorcana and non-sport cards.

HobbyGM doesn't scan or identify cards, create new listings, list on other marketplaces, or look up sold prices for your cards. It works on the eBay listings you already have, however you made them.
