Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureLinkStock syncs products and variants that share physical stock. Use Stock Groups for duplicate listings, singles and packs, with explicit Units per sale. Connect existing set variants to component recipes with Bundles. Availability is calculated independently at each selected location. Review stock counts before confirming changes, preserve leftover units, and follow updates in activity history.
Variants sharing a SKU at one location are grouped on install, with nothing to map by hand. When one changes, every variant in the group is set to match, on a schedule or right away with Sync now. History shows each variant's stock before and after a sync, with any issue explained. Set a group's stock or SKU once from its panel, leave a group out, or pause syncing.
- Link products and variants that draw from the same physical stock.
