Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureEasify Inventory Sync eliminates the chaos that causes overselling. Inside one store, keep duplicate SKUs, product variants with shared inventory, bundle inventory, raw materials perfectly aligned. With multistore sync, connect multiple Shopify stores to sync products, collections, inventory, orders, pages, blogs, metafields. Built for merchants who can’t risk stock mistakes, slow syncs, or unreliable apps.
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.
- Duplicate SKUs: Unisex tees, Blank & Personalized tees, Retail & Wholesale items
- Bundles (Set): Stationery, Top & Skirt, Candles, Perfume, Mixed Sweets, Gift Box
- Raw Materials: Roast Coffee, Tea Leaves, Herb, Spices, Salts, Baking Ingredients
- "Pack of X": Multivitamins, Beverages, Incense Sticks, Batteries, Flowers, Tops
- 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
