Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureOur app allows merchants to combine and synchronize inventory across multiple product variants, helping manage stock more efficiently. Instead of tracking inventory separately for each variant, merchants can group selected variants to share the same stock quantity. This is especially useful for products that represent the same physical inventory but are sold under different options or listings.
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.
- Create groups of multiple variants that share a common inventory stock
- Set different stock reduction values for each variant based on inventory usage
- Automatically mark linked variants as sold out when shared stock reaches zero
- Inventory pools with consumption multipliers for variants of different sizes
- Pool health dashboard showing sync status, quantities, and warnings at a glance
- Hourly reconciliation detects discrepancies and lets you fix them in one click
- Safety buffer reserves stock to prevent overselling during checkout delays

How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Nov 2, 2026 for ONE, Oct 13, 2026 for PoolSync. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
