How warehouse mapping works

A channel and SellingIO each have their own location list. Warehouse mapping tells SellingIO which warehouse in its shared stock model represents each location reported by the channel.

This relationship must be explicit before stock can move safely. A location name alone is not enough evidence that two records hold the same stock.

The mapping model

Each active channel location points to the SellingIO warehouse that owns the same physical stock. Within one connection, a SellingIO warehouse cannot be assigned to two channel locations.

A new connection can therefore be active while its warehouse mapping is still unconfirmed. That is a real setup state, not a connection error. Confirming the mapping tells SellingIO where incoming and outgoing stock belongs.

What happens while a location is unmapped

Stock from an unmapped channel location is not ingested into SellingIO. Inventory changes for stock without a usable mapping also cannot reach the platform. The connection's Warehouse tab warns about unmapped locations and recent skipped changes so you can correct the relationship.

Do not pick a convenient warehouse just to clear the warning. Map only locations that represent the same stock.

Channel-specific setup

For the TikTok controls and confirmation sequence, follow Map TikTok warehouses. That guide owns the procedure; this page only explains the shared model.

For Shopify, the first sync creates the product-to-listing links that later stock updates use. Warehouse mapping answers a different question: which SellingIO stock location backs the channel location.
