HobbyGM vs ZIK Analytics

ZIK Analytics is product and competitor research for eBay and Shopify sellers, mostly dropshippers and sellers sourcing new goods. It suits sellers deciding what products to source, rather than what to do with a store of one-of-a-kind cards.

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 ZIK Analytics does

• Competitor, product and category research for eBay. (source)
• A title builder, and scanners that match products with suppliers. (source)

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.
