Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSell one item as a single and a 3-pack, in colourways with different names, or inside a gift box? OneCount keeps them on one count. Pools share stock across variants, with packs in units. Bundles show how many you can make and take their items when they sell. Decants count the bottle in ml. Sales, refunds and edits sync in seconds, checked against live stock.
Shopify does not expose per-location inventory to your theme, so shoppers cannot see what is on the shelf in each store. Zarbo Stock by Store writes the on-hand quantity at every location into a JSON metafield on each variant, kept current as inventory moves through real-time webhooks. Use the metafield the app creates, or point it at one you already have.
- Group any variants, across products, into one shared stock count
- Set units per sale, so a 3-pack sale takes 3 units from the pool
- Sales, refunds, restocks and manual edits sync within seconds
- Write on-hand stock per location into a JSON metafield on every variant
- Stays current automatically as inventory moves, through real-time webhooks
- Use the metafield the app creates, or write to one you already have
- Trigger a full resync of the whole catalog at any time from the app
