Pool inventory across variants to prevent overselling. Real-time sync with monitoring tools.
Shopify treats each variant as independent inventory. When variants share stock, you risk overselling and spend hours adjusting quantities manually. PoolSync creates inventory pools that sync to all linked variants automatically. Set consumption multipliers for different sizes (1oz = 1 unit, 4oz = 4 units). Orders deduct from the pool and update every variant. Refunds restore automatically. Includes a pool health dashboard, hourly reconciliation, and a safety buffer to prevent overselling.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows PoolSync: Shared Inventory on a store, it is there.
