Synced. Priced. Listed.
LongboxSync pulls your ComicBase, CLZ, or HipComic catalog into one place, backs every book with PriceCharting market data, and publishes to Shopify on your terms. All in the cloud — nothing to install.

Built for comic dealers, not generic catalogs.
Raw grades, slabs, variant covers, and key issues are first-class here — because a longbox isn't a SKU list.
No more double-entry
Your catalog already lives in ComicBase, CLZ, or HipComic. LongboxSync imports it as-is — grades, variants, and slabs intact — and keeps your storefront aligned with it.
Priced with the market
Every book carries PriceCharting market guidance — price band, trend, and daily price history — so you can price with data instead of guesswork.
Publish on your terms
Nothing auto-lists. You choose what goes to Shopify, item by item, and edits to listed books push through automatically.
Everything you'd build yourself, already wired up.
Stop managing CSVs at 2am. The boring parts — OAuth, webhooks, rate limits, retries — are handled, so you can get back to procurement.
OAuth connect and per-item publishing. No API keys to babysit, no CSV exports.
Every item is hashed; only changed fields push. Fast syncs that respect marketplace rate limits.
Marketplace credentials sit in an encrypted per-tenant vault with full tenant isolation.
Import high-resolution cover scans and attach them to listings — your books look as good online as they do in the bag.
Simple pricing. No surprises.

Frequently asked
Do I need to migrate my ComicBase data?
No. LongboxSync operates as a synchronization layer. We ingest your CBIX or HipComic API data and project it to your storefront. Your source of truth remains untouched.
How does it handle graded books?
LongboxSync recognizes CGC and CBCS certification and condition strings, and maps grade and cert data into your Shopify listings — so slabs stay slabs, not just another variant row.
Will it auto-list my whole collection?
No. Imports are ingest-only. Publishing to Shopify is a deliberate per-item action, and auto-publish stays off unless you turn it on.
Where do prices come from?
Your price always wins. If a book has no price set, PriceCharting market guidance is there to fill it in — and nothing publishes without a price.
