See every feature424 Inventory Sync keeps stock levels consistent across products and variants that share a SKU. When inventory changes from sales or edits, it mirrors available quantity per location to all matches—automatically. It’s lightweight and focused (no bells and whistles) with a manual “Sync now” fallback.
Duplicate product listings with the same SKU are common for unisex products, men's and women's pages. Shopify still deducts stock from only the purchased variant. Spot solves that same-SKU syncing problem without turning every location into one pool.
