Sync unlimited product inventory levels between stores

Automatically synchronize inventory across multiple stores.


Connect, Copy, and Sync Products Between Multiple Stores


Keep a second store in step with your first — products, variants and stock, automatically.
Multi Sync keeps two or more Shopify stores in step, so nobody re-keys a catalogue twice. Edit a product in your source store and the connected stores follow — title, description, images, options, variants and prices. Sell in either store and the other knows: inventory syncs both ways, with loop protection so changes never bounce back and forth. You decide what crosses: filter by tag or status, choose which fields sync and which stay local, and set what happens when a product is removed.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Syntonic Multi Sync on a store, it is there.
