Stop Overselling When Variants Share Inventory
PoolSync automatically manages stock levels across all linked products and variants — with the monitoring tools existing apps don't provide.
Shopify treats every variant as independent inventory. Your business doesn't work that way.
Manual inventory hell
Adjusting 20+ variants every time stock changes
Overselling during sales
Checkout delays cause multiple customers to buy the same stock
Silent sync failures
Apps break without warning. You find out when customers complain.
Built for merchants who share stock across variants
Material Sellers
Sell lavender oil in 1oz, 2oz, 4oz, and 8oz bottles from one 500oz master pool. When a 4oz bottle sells, pool decreases by 4 automatically.
Bundle & Kit Sellers
Sell beans by the bag and in a Coffee Lover’s Kit. When the kit sells, all component inventory adjusts automatically.
Made-to-Order Stores
One frame design, 20 fabric choices, 50 total frames. Any variant selling deducts from the shared pool.
