Setting up your Shopify account to properly pull in your inventory is a little different than most marketplaces, as Shopify allows multiple inventory locations within the Marketplace itself. Because Listing Mirror will be sending inventory to Shopify, you'll need to set up your Shopify Locations properly.
All this means is that the default location in Shopify must match the location selected in Listing Mirror!
If you head to Integrations>Channel Integrations and click in to edit Shopify, you'll see the Locations dropdown in the General tab toward the bottom:
If you click on this dropdown it will provide all locations currently assigned to your Shopify account, you'll want to choose the one that is default on Shopify, this is typically an address.
You'll also want to make sure that no 3PL (FBA, Deliverr, etc,.) are still showing in this dropdown menu!
Once the correct Location is chosen, Listing Mirror should be able to send your QTY to Shopify!
