Precision engineering for comic shops.

We map raw grades, CGC-certified slabs, and variant covers directly into your storefront schema. No generic compromises.

Automated Grade-Mapping

Eliminate Sunday reconciliation. LongboxSync maps CB condition codes to Shopify variants with pixel-perfect accuracy.

Unified Cross-Marketplace Linkage

Shopify, eBay, and Etsy stay anchored to your ComicBase source. Sell a CGC slab on one, and it's delisted everywhere instantly.

Zero-Migration Deployment

Your catalog stays in your existing software. We layer over your ComicBase, CLZ, or CSV exports without a single data-migration headache.

Infrastructure you can trust.

Stop managing CSVs at 2am. We've built the enterprise-grade synchronization engine so you can focus on procurement.

Protocol FAQ

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 storefronts. Your source-of-truth remains untouched.

How does it handle graded books?+

We recognize CGC, CBCS, and PGX certification numbers and condition strings automatically, mapping them to rich Shopify metafields for SEO-friendly listings.
