HobbyGM

Every card in your eBay store, checked every night.

HobbyGM is the general manager your card store never had. It reads every listing and finds the titles buyers can't search for, the specifics you left blank, the prices out of line with the market, and the cards nobody is watching. Then you fix them without leaving the page.

What gets checked

Four checks run on every listing after each sync. Every flag says what's wrong and what to change.

  • Titles buyers can find

    Each title is read like a card: year, set, number, player, parallel, grade. We flag the terms collectors search for that are missing — RC, the print run, the grader — and titles that waste characters.

  • Complete item specifics

    eBay's filters run on item specifics. Listings missing Player, Parallel, Graded or Autographed drop out of filtered searches, so we list exactly which fields are blank.

  • Prices against the market

    Every card is compared with other sellers' current listings of the exact same card: same player, set, number, parallel, grade and print run. You'll know when yours is the priciest copy on the page, or the cheapest by a mile.

  • Cards nobody is watching

    Listings that have sat for weeks without a watcher get flagged with a next step, from a markdown to a promoted-listing rate, scaled to how long they've been stuck.

Made for big inventories

Card stores run to thousands of listings. The app is built around that instead of a spreadsheet.

Background syncs
Syncs run on our servers every night and resume where they stopped, so a 10,000-card store never needs a tab left open.
A queue, not a report
High-severity flags come first, ranked by how much money is at stake, then by how long the card has been sitting.
Edit in place
Change a title or price and it updates the live eBay listing, with a record of every change you've pushed.
Pinterest boards by player
Group your cards by player, create a board for each, and pin listings to bring collectors in from Pinterest.

How it works

  1. Step 1

    Create an account

    Email and password, or Google. Takes a minute.

  2. Step 2

    Connect your eBay store

    You sign in on eBay itself and approve read access plus title and price edits. We never see your eBay password.

  3. Step 3

    Work the queue

    Your whole store syncs overnight. The dashboard lists the highest-impact fixes first, and edits go straight to the live listing.
