The 2026 Comic Inventory Software Buyer's Guide.

Most comic inventory software was built before iPhones, and most reviews focus on the wrong axes. This guide focuses on what actually matters in 2026: how fast can you catalog, how accurate is the pricing, and how easily can you sell the books you own.

The contenders

• CLZ Comics: Mature desktop and mobile catalog. Strong on cataloging, weak on selling.
• ComicBase: Windows-only with the deepest catalog database. No mobile, no marketplace publishing.
• Key Collector: Mobile-first price guide and want-list. Not a true inventory tool.
• ComicHub: Newer mobile-first competitor. Limited marketplace coverage.
• Stash Management: Mobile-first scan workflow, AI slab/press analysis, 12 marketplaces.

The five axes that matter

1. Speed to catalog

How long does it take to add a book to your collection? Desktop tools assume keyboard entry, 30 seconds per book at best. Mobile scan-first tools (Stash, parts of CLZ, ComicHub) drop this to 3–5 seconds. If you have a backlog of 500+ books, this single axis dominates the rest.

2. Pricing accuracy

Static price guides update annually. Live-data tools like Stash and Key Collector pull current market prices. The gap is usually 10–30% on hot books, meaning if your tool isn't live, you're systematically over- or under-pricing.

3. Grading intelligence

Does the tool tell you whether to slab? Whether to press? Whether to clean? Only Stash currently offers all three. The math here is concrete. A slab decision is the single highest-leverage choice you make per book. And most tools leave it to you to guess.

4. Marketplace publishing

Can the tool actually sell your books, or just catalog them? CLZ exports to eBay (one platform). Stash publishes to 12 (eBay via API, 8 via CSV, 3 via manual logging). ComicBase, Key Collector, and ComicHub don't really publish at all.

5. Multi-seat for shops

If you run a comic shop or auction operation, you need per-user logins, custom SKU fields, and org-wide reporting. Only Stash's Shop tier ($200/mo) addresses this on the SaaS side. ComicBase technically supports it via per-machine licenses, but the workflow is dated.

Picking by use case

If you're a personal collector under 200 books

Use Stash's free tier. Mobile-first scanning, live valuations, slab analysis, no subscription cost. If you outgrow 200, the $5/mo Collector tier covers everything.

If you're a personal collector over 200 books

Stash Collector tier ($5/mo) or CLZ ($30/yr) are the realistic choices for cataloging plus live pricing. Stash wins if you care about live market values. And the Seller tier ($19/mo) adds selling across 12 marketplaces if you ever go that way. CLZ wins if you exclusively want a catalog and don't need pricing or selling features.

If you're a dealer or comic shop

Stash Shop tier ($200/mo) is the only true SaaS option with multi-seat and org-wide reporting. ComicBase remains relevant if you run a POS-adjacent shop on Windows and need the deeper catalog database, but it doesn't sell anything.

If you mainly track keys and want lists

Key Collector is purpose-built for this and excels. Use it alongside Stash if you want both a key tracker and an inventory tool.

If you run an auction house

Stash Shop tier. The only tool that integrates with all four major comic auction houses (HiBid, Heritage, ComicLink, ComicConnect) and tracks consignments through the realized-price cycle.

The honest summary

CLZ and ComicBase are mature catalog tools that have aged. They're fine if cataloging is all you want. Key Collector is excellent at its specific job (key tracking) but isn't an inventory tool. ComicHub is a credible newer player but hasn't caught up on AI features or marketplace breadth.

Stash is the only tool that combines scan-first speed, live AI pricing, and full marketplace publishing, which makes it the right pick if any of those three matter to you. If none of them do, the legacy tools are perfectly fine.
