Keeping store inventory connected to the marketplace
For business leaders managing manual processes, another sales channel adds inventory work. We connected HobbyMP with Shopify catalogs, stock updates, and seller publication controls.
A seller already has a store to manage
Selling through another channel can mean maintaining another copy of the catalog. Stock changes and publication decisions need to travel between systems.
We built HobbyMP's Shopify connection around the seller's existing store, with catalog import, inventory updates, and controls for how listings appear on the marketplace.
Connect the catalog to marketplace operations
Bring store products into the review flow
The connection imports Shopify variants and matches them against HobbyMP's catalog. New matches become draft listings for seller approval; existing mappings support subsequent updates.
Respect the seller’s publication decisions
Incoming inventory events update mapped listing quantities. The application also includes outbound inventory adjustments tied to marketplace orders.
Sellers can require another approval when sold-out stock returns. A listing deliberately held in draft remains under seller control when inventory changes.

Handle updates as an ongoing workflow
We added event records to identify duplicate Shopify notifications and background jobs to process updates. The integration tracks outgoing changes to reduce updates echoing between the two systems.
Disconnect handling archives connected listings. These mechanisms give the integration explicit behavior when the store relationship or incoming data changes.

Extend the marketplace into existing store workflows
The integration connects a seller's store inventory with the marketplace's catalog and approval process. It gives the product a defined relationship between external stock and local listings.
This work extends the original commerce application with the synchronization and operational controls needed to support another sales channel.
