See every featureSeveral listings share one shelf of stock. Shopify tracks each variant separately so one sells out while the others still show stock. PoolKeeper gives those variants one shared pool. Set the quantity and how much each variant uses; every sale or restock resets the others to match. Multipliers handle packs and weight. Compare-and-set writes never overwrite a sale in flight.
You already created a pack in Shopify. Shared Stock Sync does not create packs. It keeps pack stock honest so you do not oversell kits. With 6 blue tees and 10 pink tees, a pack of one each can sell 6 times. A blue tee sale drops pack stock to 5. A pack sale deducts one of each. Link the pack to each product and quantity needed. Stock updates when inventory changes or a pack sells.
- Compare-and-set writes: never overwrites a sale in flight, so no overselling
- Multipliers for packs and weight: 6-packs, 0.5 kg bags, metres of fabric
- Full audit log of every sale, restock and correction, with before and after
- Hourly reconcile and a stock buffer keep every listing accurate
- Pack stock matches how many complete kits you can still make.
- When a pack sells, the products in the kit are deducted.
- When a product sells on its own, pack stock updates immediately.
- See calculated pack stock and whether sync is up to date.
