FireCardManager vs. Kronozio
Kronozio (the Kronocard software) is one of the few tools that, like FireCardManager, treats inventory as the center of the business: flatbed scanning with “magic cropping,” AI documentation, eBay sync and sales reports. Kronozio also runs its own marketplace.
So this one is closer than most. Here’s where they line up and where they don’t.
The 30-second verdict
A solid inventory system with two-way eBay sync and very large listing runs. Monthly plans, with exports beyond eBay as a paid add-on.
Inventory plus listing to eBay and Slabs & Singles, Shopify and Whatnot CSVs included, and no card limits, for $59.99 a year.
What a year of listing actually costs
Kronozio publishes an entry plan; above 500 cards a month you’ll need to ask them. Here’s the comparison at the published tier, with and without the export add-on.
Feature face-off
| Kronozio | FireCardManager | Edge | |
|---|---|---|---|
| Price | $8/month entry plan for 500 cards; higher volumes not published; $24/month export add-on | $59.99 a year (or $39.99 for 6 months), 30-day free trial; unlimited cards | FCM |
| AI documentation | Included; Kronozio cites 92% accuracy on raw cards | Bring your own Claude or Gemini key: about $0.42 (Claude Haiku) or $1.49 (Gemini Flash-Lite) per 1,000 cards, paid to Anthropic or Google | Tie |
| Scanning | Flatbed or feeder with magic cropping and front/back pairing | Flatbed, ADF, overhead SV600 with auto-crop, camera, or images from any scanner | Tie |
| Inventory | Core of the product; spreadsheet-style editor and sales reports | Virtual storage boxes with box/row/slot, lot and collection boxes, search, Sold Log | Tie |
| eBay | Listing with two-way sync; very large runs | Bulk Lister with shipping profiles, offers, auctions, scheduling and templates; live listing view | Kronozio |
| Other marketplaces | Kronozio’s own marketplace (free to list, 10% commission); other exports via the add-on | Slabs & Singles direct (same SKU, auto delist), Shopify and Whatnot CSV, all included | FCM |
| Pricing data | Not described on Kronozio’s plan pages | Verified sold prices with a free CardSight key, or AI estimate | FCM |
| Where it runs | Desktop app with a Kronozio cloud account | Windows desktop; data stays on your PC | FCM |
This is the closest matchup in the series. Kronozio’s two-way eBay sync and big runs are real strengths; FireCardManager’s edges are price, included exports and sold-price data.
One batch, start to finish
A run of 100 cards from scanner to live listings.
- Scan on a flatbed; magic cropping splits the cards and pairs fronts and backs.
- AI documents each card.
- Review in the spreadsheet-style editor.
- Sync to eBay.
- Inventory updates as cards sell.
- Scan on a flatbed, ADF or SV600; fronts and backs pair and AI identifies each card.
- Cards are filed into box, row and slot.
- Update prices from verified sold data.
- Send the batch to the Bulk Lister and choose eBay, Slabs & Singles or both.
- Sales land in the Sold Log; a sale on one marketplace removes the other listing.
Which one fits you
Pick Kronozio if…
- You want two-way eBay inventory sync and very large single runs.
- You’d like Kronozio’s own marketplace as a sales channel.
- You list under 500 cards a month and only sell on eBay.
Pick FireCardManager if…
- You sell on more than eBay and don’t want to pay extra to export.
- You list more than 500 cards a month and want a price you can see up front.
- You want verified sold prices built into the same app.
Where FireCardManager falls short
- Windows only, one PC per license.
- eBay listings don’t sync back two ways the way Kronozio’s do; FireCardManager watches its own listings and sales instead.
- AI identification needs your own Claude or Gemini key.
- Pre-release software.
The bottom line
If you’re a flatbed-scanning, eBay-only seller under 500 cards a month, Kronozio’s entry plan is good value. Once you list more, sell on more than one site, or want sold-price data, FireCardManager covers it all for one annual price with no add-ons.
