Brand
Open it: Settings → Brand (brand admins).
This opens your brand record — its identity, plan, and selling channels. Edit the identity fields and choose Save.
Under How you sell you turn your selling channels on or off — your online store and/or in-person selling (Point of Sale). This is what makes the matching sections appear in the admin and on your storefront.
Internal infrastructure fields (cluster, shard, commerce-company links) are managed by the platform and aren’t shown to you.
