Shared inventory sync
A sale on any connected channel updates stock on the others, so the same card isn't sold twice.
Marketplace Sync
One inventory. Connected marketplaces.
Connect CardNexus, Cardmarket, eBay, TCGplayer, Cardtrader, and Mana Pool to one inventory, with Shopify as the source of truth and CardSynced pricing data and supported listings alongside. Supported stock, listing, and order workflows stay together without duplicate spreadsheets.

- eBay, TCGplayer, Cardtrader & Mana Pool connections, plus CardSynced pricing data
- Shared inventory sync — sold on one channel, updated on the others

- Condition-aware listings per marketplace
- Channel-specific pricing rules
How the sync works
One brain, many storefronts
The hardest part of running a multi-channel card shop is keeping inventory accurate. Sell one NM Black Lotus and the same card needs to disappear from every connected listing before it can be sold twice.
Channel pricing rules
Set different margins and fee buffers per marketplace while keeping your storefront pricing independent.
Unified orders
Orders from the storefront and every connected marketplace land in one pick list with addresses, labels and tracking, so a single packing run clears the day.
Conflict resolution
When two marketplaces buy the last copy at the same time, we handle it cleanly with automated cancellations and refunds.
Condition-aware
Each condition (NM/LP/MP/HP) can remain a separate listing where the connected marketplace supports it.
API-based marketplace connections
CardNexus and Cardmarket use their official APIs with credentials from your seller accounts. Connection details and write scopes are validated during onboarding.
